86 Savage Electrical Issues
05/06/13 at 12:04:27

Hello everyone,
I am having a major problem with my 86 Savage. Whenever the bike warms up to running temperature I lose spark to my spark plug. I just got my baby back from the mechanic who has had it for 6 months and could not figure out the problem. I am about to tackle this project myself and if I could get help narrowing it down to the one part that needs replacing it would be greatly appreciated. I was thinking I might have to get a new main harness because that is the only part of the electrical system that looks bad to me. I don't know if this is relevant but before I sent the bike to the shop it would start turning over as soon as the battery is hooked up with no key in the ignition or anything. The mechanic never mentioned the bike doing so when he had it so I don't know. He only said that when he test drove it that it would lose spark when the bike heats up. Please help!

It could be a lot of things. The first thing I would do is wire a small light bulb into the red wire on the coil, and run the other end to a ground. The light should be on whenever the coil is getting power. This will show you if power is going to the coil.....and if any of the safety circuit is taking the power away from the coil as things heat up. If that does not change - then you need to look at the other side of the coil toward the igniter side......not sure how to test that...maybe there is a test process in the manual....I will look.

It seems as if another member had a similar problem last summer or fall. Anyone remember or possibly have a link?

I think that was the decomp controller that went bluey.
maybe "ghost start" will find something

here you go...

Maybe you could find a wiring harness on ebay and start from scratch. Seems that would be easier than sorting out that mess of wires.

Posts: 28668 Tucson Az Gender:	Re: 86 Savage Electrical Issues Reply #11 - 05/06/13 at 17:57:56 Jeepers!... that bike looks like it was parked under the pier for a while... Firstly,.. I'd jumper bypass the clutch, and sidestand cut-outs... (just to eliminate them from the power chain)... (you could put them back, later, after you find the cause)... It could be corrosion in one those switches... ...

Just being close enough to the ocean can do that from the salt air, usually happens when the protective clear coat is missing or even worn down to minimal. I grew up in a sea side community and had it happen to bikes and cars. Sad
