I struggle with th eignition on my old engine... How can I repair/get a new rectifier to a 4,5 hp (1976) Mercury (it´s a Thunderbolt Ignition syst.)?
I have an old but it used to be very good Mercury 4,5 hp and last summer it died. I managed to buy used parts via ebay for the ignition system (rectifier)+coil.
I managed to get a spark yesterday, but I get really funny measurements from the rectifier and the maintenance handbook does not lead me right. However, I guess that the rectifier might be faulty. At least some of the diodes in the rectifier are faulty I conclude.
Since there are no new parts I have to rely on used or build new ones. I would like to replace the diodes but then I need a blueprint for how it is once made. Can you help me on that or any other good idea how to solve the problem?
