Electrical issues

Hello everyone,

So I have currently put the 86 shadow on hold because I need to take the engine out. 😞

In the meantime I came across an 85 that I figured I could use for parts. When I got this bike I was told it had electrical issues so I dove into this head first.

When I turn the key I get nothing. No headlights no dash no starter button. I bought a multimeter and started checking bolts as I've read other posts. When testing battery I have 12.8-12.9v. When tested to the starter relay I get the same.

I removed the headlight to get to the wiring harnesses. Tested main wire from harness to ignition and I get 12.8v. Tested the br/w and br harness and I get nothing. Both with key in on and off position.

So... bad ignition? If not... where to go from here?

As always thank you guys for the help!!

Kill switch, Main switch, Grounds etc... Connections Aughtta be clean & Tight...
Be sure to Check them battery connectors @ the both ends for corrosion and good tight crimps...

I'd say check ignition key switch its self. My 84 has a small issue where the ignition switch is a bit warn, I have to juggle the key sometimes to get any power. I'm procrastinating on changing it out because ATM all my locks on the bike are still matching the original key lol

I would start by opening up the small black fuse holder for the 30 amp main fuse. It powers the whole system. It is a funky old fashioned thin metal strip screwed onto the holder and on mine it was corroded and barely touching the end. Put an inline fuse holder to eliminate that as a weak spot. Jump across it first to see if everything lights up.
Here is how I changed mine.
Check the 3 yellow wires while you are there .

I just thought of one more thing. I saw a fellow here had posted an electrical problem and his connector at the fuse box on the dash had bad connections and burned the 2 main bus bars to the ignition switch. This is what the fuse box and buss bars look like.

Progress!!

So I took the ignition switch from the 86 and put it on the 85. Voila! I get power now.

Now when I push the starter button it turns over. It won't start.

So I think the choke is the problem. The lever won't move so next step is to trade Cooke levers between the two bikes.

Gotta tell ya I was so happy to hear it trying to kick over with starter fluid! 😁
