|Wipac Series "A" impulse magneto
|Posted on Friday, January 22, 2010 - 09:57 pm: ||
I am looking for a copy of a manual for a Wipac Seies "A" magneto. I have just purchased a Stuart Turner P66 and I am going through the learning process of trying to figure out how everything works. When I purchased the engine it had been sitting in a shed for many years and no wiring was connected. I am not sure where the centre cable from the distributor cap attaches. From pictures I've gleaned from the internet it appears that it should attach to the lug on the back of the cap on the magneto, however the cable is 600mm long and looking under the magneto cap there appears to be nothing but a small bronze clip. Any thoughts on the subject would be most helpful. To date no spark, but I'm working on it.
If anyone is able to email me a copy of the Wipac manual I would really appreciate it. I've already gleaned lots of useful info from the technical section. A fantastic, valuable tool.

OK. I've just spent the afternoon running through the set up proceedure. I identified my Wipac magneto as a "Type A1752D" which has a (broken) projecting lobe at the rear of the plastic cover and push in leads. After removing the broken insulating material from the lobe I was left with an exposed "pin" (see attached photo).
The ST manual states that with this type of magneto that the spark occurs as the points close.
However, I observed that my points were closed until I heard the impulse click and then they were immediately open.
The manual then states "turn the flywheel back slightly until the points open ..." - I didn't need to as the points were already open.
My magneto is acting more like the High duty magneto described in the ST manual.
The photo I have attached shows the magneto as it is now. At this stage I dont even know if its complete.
Can anyone advise. Many thanks, Ken.

The main problem is that it is missing the Coil which sits in the space above the Rotor, between the two posts. There is an end cap which fits over the Rotor Button, (held on by the 2 clips) and a short lead to the single terminal on the main cap and 2 leads that go to the spark plugs. Without the Cap and the Coil it is useless.

David had new Wico A twin mag last time I spoke to him, it wasn't too expensive either.
He regularly goes out of the country, so you may wait for a reply.

Firstly I would like to thank everyone for all the kind offers of help and advise. As luck would have it I managed to locate a Wico mag locally and burgled it for parts and built a good one from the two, so I now have a very healthy spark. To date I have not yet fitted the impulse mechanism to the mag so it is still un-tested on my P66. I will keep you all posted on progress. Next mission is to strip and clean the carb, then a service of the water pump.
Todd, thank you for your generous offer to bring spares with you to NZ. At this point in time all is well, but I will be in touch with you at a later date. Enjoy your time in NZ.
Thanks again. Ken
