    Need wiring help on a "81 185s

    Ok, I just scored a "81 185s for $25. The problem is it's been sitting for years, and someone stole the pull start and the cdi box(the little box next to the coil?)and rats have ate all of the wiring that was accessable to them. I have a repair manuel for it, but it dosn't list what color wires go where. It feels like it has good compression, but my compression gague does not fit the small spark plug hole, so I'm trying to figure out how to make it run without spending a bunch of money. Can enyone give me a wiring diagram of what goes where, or how to hotwire it to see if it even runs before I go spending a bunch of money on it? Any hely is greately appreciated. Thanks Dough

    It should show you a wiring diagram in the back of the manual, if not, check here, do a search for service manuals, and you will get an idea. If it is in that kind of condition, you have to expect to spend a little money on it, it not going to repair or replace worn parts on its own.
    It may be easier to buy a complete wiring harness, and CDI if the wires are that far gone. I have seen wiring harnesses on ebay for that model sell for about $10 or less. Just keep an eye out on there if you think you need one.

    Yamaha I don't think you understand my problem. Even If I buy a cdi and wiring harness there is nothing to plug it into. I would need the pigtails off off everything electrical to make a harness work. I need to build my own wiring harness.
