The wiring diagram I made probably looks simular to an Ace 90 because I was basising it off of an Ace 100 B+ haha. I agree with what you said 100% but only problem I have is the brake light/turn signals are LED and must be run off of DC. I think the one improvement I could make is instead of combini...

So here’s what I got for a wiring diagram....I think this should work

Thanks Roger that’s a lot of useful information! However it does bring up a couple questions...First off does the headlight have to have AC Power? I was able to make it light up both low and high beam using just a 6V battery. Then if I have a on/off switch directly on my headlight and a low/high bea...

Hey guys, I have a 1972 Ace 100B+ and am trying to figure out what the yellow, blue, green, and black wires that come out of the magneto and go to the keyed switch do. I have a wiring diagram but in the process of making a custom wiring harness since I’ve added turn signals and a new control switch ...

Al that actually ended up being sort of the issue surprisingly. The spark plug wire broke at the tip so I just cut it off and moved the cap down alittle bit and got 5.1k ohms in the secondary. Still no spark from the Champion J4C spark plug though...now at the next hurdle

Al, thank you that was very useful. I was able to measure 2 ohms on the primary but wasn't able to get a reading on the sdconday. I didn't have a time to really dive into but will look further in the next couple days.

Thanks everyone for the help but no need for kill switch as no fuel is being introduced at the moment just trying to get spark from the spark plug when grounding it outside of the combustion chamber! Is 2-3V enough coming out of the magneto at the connector just before the coil?

Here is the same wiring diagram with all the extraneous bits removed. All that is left is the ignition circuit - without the main switch. tech_Acewir IgnitionOnly.jpg Ed Ed, from this picture would you have to jump the black and blue and the green and yellow coming from the magneto in order to have...

Hey guys need some expert advice as I'm pretty new to hodakas. I've been fighting a spark issues for a while now. I'm trying to figure out if it's something in the wiring harness or something mechanical. I currently measure 2-3V leaving the magneto, is this enough? If not then it's either the igniti...

Thanks everyone! I'll take it back apart and double check the magneto here in the upcoming weeks.

Alittle background, I recently was gifted a Ace 100B+ that was found in a barn. The engine was filled with water but has been completely rebuilt. Now I'm trying to get it to fire up but have no spark. I am getting 4 Volts at the spark plug connector (Very low) which points me towards the ignition co...
