The advice I gleened from my last visit to the site, has my little stuart P5 running very sweetly, thanks to all those that helped.
The same engine is turned over very nicely by the dynastart, however I am not sure how to wire it for charge? For example which wire goes where and should it have a cut out? I also notice on a previous thread that peter has mentioned the belt running on a sprocket, mine seems to run directly on the flywheel, I haven't seen any pictures to compare setups, so if anyone has any I would be grateful for a look. thanks |

Will ...I will send you a circuit diagram of the dynastart
As a matter of interest what was the cure for your P5 . It is always good to get feedback on things like this |

Peter, a circuit diagram would be fantastic, does it mention where abouts on the dynastart the wires go? Do you need email or can it be posted here? my email is [email protected] if needed.
The cure for the P5 seems to have been a bit of a combination of fine tuning. I tilted the carb back slightly, drained the crankcase and recleaned the sparkplug, she seems to be ticking along nicely eversince. I'm not quite sure which action was the cure, but I am definitely carrying a spare plug or 2 at sea! Also uped the fuel oil mix to that which you recommended. |

By the way peter, are you still planning on a clinker boat as I read in a previous thread. You were asking back then if wooden clinker needed to be in the water all the time. The 15 launch that my P5 is in is clinker - mahogany on steamed oak ribs. It sits on a trailer the majority of the time. I have treated below the waterline with "ISOFLEX" a synthetic rubber paint used in the building industry. So far the hull seems as continent as a fibreglass equivalent and looks more in keeping with her engine. |

Will, I have clinker boats on trailers and they seem to manage alright as long as they are protected from the very hot days we can get in summer here in Melbourne. My boat gets regular use about every month to 6 weeks and takes up quickly when back in the water. On the hot days I splash a bucket or two of water around to keep things damp. If used in salt water,I always leave whatever remains in the bilge after use. I drain it of fresh water though and store dry. Clinker boats seem to get used to being mostly dry and if you restore and repaint in that condition there should be little movemement after that. |

Will ,you should now have that wiring diagram. Re my boat ,she is Carvel hulled under cover and sitting on a trailer,............there just seem to be so many other things to do , priorities in order is the answer!!!!!
I am trying to get a little Stuart Turner R3M engine finished to take to the 10th National Rally in South Australia early next year.

Peter, Tim Mulvey has very kindly sent me a couple of wiring diagrams. Sadly I don't think either are for the dynastart I have, which is belt drive and Siba?? plaque worn. I don't suppose you have any photos of a similar set up?
Sad to hear that the boat isn't having much exercise. I came back from the Brisbane waters area last year, lovely place for putt putting! Is an R3M similar but smaller than a P5? |

I found a 3 page article on wiring and maintenance of a Siba Dynastart from the Feb 1968 edition No. 14 of the Practical Boat Owner magazine (UK) that I have emailed to Will. Its too large to post here and not the best reproduction that I scanned.
Others who want it can contact me direct. |

I have what I am told is a dynastart but may be a starter motor It is a Bosch 221 and has 4 brushes, a d+ and D terminals also a large terminal marked 30 can anyone identify this unit and confirm what it is. I would like to fit it to my Stuart P5 engine
Thanks

Hello chaps. I have just inherited a yacht with a Siba Dynastart on an ancient Stuart Single Cylinder 2stroke. Starts OK but no charge. What's chance of a glimpse of a circuit diagram? |

I have a Macwester 27 with a shoehorned Volvo MD2 in it which is started and charged by a Dynastart. The last one I bought was in Falmouth 18 months ago from Lucas Marine. It is an Italian make, and it has now burned out according to my local Lucas. I wonder if anyone has a wiring diagram to show which wires go where from the Dynastart to the regulator and switchgear. Any help much appreciated |

Hello, can anyone help please? I have recently had my old Stuart Turner P5 reconditioned and also added a Siba Dynastart MkII. However the Dynastart was not connected via pully to fly wheel nor was an adjuster arm etc provided. Any suggestions for the correct belt, v belt is suggested but the pully has a grove and fly wheel does not also where on the engine should the fixed end of the adjuster arm (when I get one) go? I have a leaflet but it is not clear. Thanks |

Cilla, Dynastart on my P55 runs off a pully (about 15cm diameter at a guess), attached to the front of the flywheel.
It could also run off the flywheel directly even if not groove as long as the dynastart pulley aligns it correctly. The only issue with running off the flywheel will depend on its size as if flywheel is large like on P55, it will turn the dynastart too fast.
If you send me an email I can send you a picture of my engine at the front showing the dynastart and pulley. |

David, thank you very much for the picture, I will take it to the engineer this morning he was considering making a groove in the fly wheel, but was concerned about ratios. Meanwhile the fly wheel which was moving freely a couple of days ago has decided to stop, total mystery.
John, it was from Fairways Marine cost including vat about £400. Try 01376 572866 but they are not answering at present, see the Classic Boat Website, news they seem to be having a bit of trouble at the moment, sadly. |

I have a siba dynastart which works great (on my volvo MB10 twin)driven by a belt wrapped round the flywheel (no groove)like my stuart P55 was on my last boat and the ratio seemed fine. However I would like to know more about the workings of the control box if anybody has details?? I have been warned that if the dyna is motored without the battery conected the control box is instantly destroyed! I have a wiring diagram if anybody still needs it. |

I am currently in the process of bringing life back to a P66 which has not run for twelve years.
I have succeeded in getting the engine to run and while in gear and thus under load, it runs superbly. However, when I dis-engage and allow the engine to idle, the revs go very high.I have been told by "An expert".....that this signifies the crankcase oilseals are gone. My feeling is that this would give too high an air ratio to fuel and thus it would stall... I would appreciate the advice of the genuine experts...The owner and I are determined this little gem of an engine is staying, but would like sensible advice from you if possible...
Thanks |

Same engine......P66 is fitted with an overslung alternator. While this charges the batteries very well, the owner would like to use the "Dynastart" found in the forward locker to start the engine.I feel there is a way to mechanically fit and run both, but is it okay to allow the dynastart to continue turning after start, without connecting its output to the batteries. The ideal situation is to start on "Dyno", and charge using the more efficient alternator.......Your views and any advice would be very welcome... |

Paul,
Check to see that the Choke/Starter Cam on the linkages is off. Silly as it may seem. In Neutral it will cause the motor to race. Also check that the Carby Butterfly shaft is not worn. If it is then air can leak around there and also cause high idling speeds. Just an observation. Very rare for P66's to have bad Crank Seals.. But.. Standing can make them hard and loose tension. Recently fired up a P55 that had been standing for 17 years. Cleaned the points and plugs, run some oil down the Cylinders and Loaded up with fuel. 3rd pull and she was away.. a little smokey but running. Great motors.
Cheers, Dave. |

hi Paul!
Being belt driven the dynastart is always turning! The charging circuit should still be okay even if not wired! They only charge when field circuit is excited! You need the regulator for this & to stop it 'cooking' the battery! If your got one great! otherwise you need a 15 amp regulator, hard to find

I can highly recommend the DVR2-S solid state regulator available here:
http://www.dynamoregulators.com/dvr2-series.htm
We put this in to replace our ageing mechanical regulator on our P5M and it does a great job.
It'll only produce 8 amps continuous but that's been more than enough for our purposes.
You'll still need a starter relay if you want to use the dynastart to start the engine, however.
Hope this helps. |

Strangely enough the regulator(bosch) out of
the earlier VW Beatles (12 volt) is perfect for the
job. You can get them from the auto dismantlers cheaply(condition unknown,no warranty)
Or you can still buy them new but expensive (aud $300) Part # 0 190 350 063.They even come with the
wiring schematics on the out side of the regulator

I'd be wary of VW regulators! the cutout is to high at 22 amps and can burn out your valuable dynastart! Aftermarket replacement regulators for US lawn tractor,golf carts with dynastarts are the way to go! we have bought of ebay motors and used without problems!

Paul- dont think think the dynastarts fitted to these engines can put out much more than 11 amps, so a burn out seems unlikely.
I did look at dynastarts for golf carts (looking for a cheap source), and I did not see any engine driven units. So is the golf cart Dynastart the manufacturers name for an electric motor? |

hi George- the problem is that they don't cut out early enough to stop the generator from heating up and burning out! voltage regulators protect both generator and battery. The dynastart is a generic term for a starter/generator as the Americans call them. Bosch made them in Germany, Siba in England & Delco Remy in USA. Yamaha, Kawasaki also make them for their golf carts but are expensive so aftermarket replacements are the cheapest option! Most of these are still belt driven. P |

I was getting loads of motors thrown at me when I googled for buggy dynastarts, thats when I got confused.
I googled Yamaha and got back from ebay a new dynastart for £123 !. Thats much better than the price wanted for a "marine" variety. Could be just what I want. |

We have a 7-1/4" gauge railway locomotive driven by a Villiers 197cc motor fitted with a Siba Dynastart. The motor can be started in either the forward or reverse direction. However when running in forward direction, the dynamo only produces 1 or 2 amps (which is insuffient to operate auxiliary equipment); when running in reverse it produces about 9 amps (which is correct when the starter has just been used). Is there a way of correcting this, so that it charges properly in the forward direction? |

Yours is a brain teaser Nick as dynastarts fitted to Stuart Turners are wired internally such that, regardless of whether you have a positive or negative earth, rotation is always in the same direction. Thinking back to Fleming's left hand rule, the relationship between Field and Current is preserved hence Thrust is only ever in one direction.
I can only suggest that the feed to the commutator in your dynastart must be independent of the supply to the electromagets- hence the ability to start the engine in either direction (do Dolphin engines use the same starting mechanism? If so, they're still alive and well in St Austell, Cornwall and worth a buzz on 01726 824 726 to find out how they do it).
From what I understand of dynastarts, they are reliant on the magnetic field being produced by electro magnets. The same magnets are used to provide the force to start the engine. From the syptoms you describe, I think the 'field' voltage (used for charging and hence a low current supply to the electro-magnets) may have failed. The 1-2 amps you see when running in one direction is probably generated as a product of the 'residual magnetism' in the electro-magnets. |

If it's a starter generator it should be the same as this.
http://www.ihcubcadet.com/forum/messages/106/36617.jpg
Yours may not have the L terminal, this is to compensate for a load, don't worry about it. |
