Electrical help needed

Ok so heres the deal, I've got an 83 650 maxim that was chopped by a previous owner. While his welds were great, and the bike rides and generally runs perfectly, but while he was chopping the frame he also chopped the wiring pretty badly. Ideally I need to make a new wirring harnes for the bike, but thats just not in the plans for right now, so I have to deal with what I've got. The biggest help I could get right now would be a quick primer on this bikes electrical system, there are alot of components missing from my system, and while I know it will run in its current configuration I'd like to know what I do and do not have in my system. I've been reading through the post here for awhile now and realize that there are some cats on here with a really good knowledge of the maxim/secca motorcylces and was hopping someone here could help.

 

The easiest solution is for you to pick-up or borrow a workshop manual and review the Ignition, Charging and Safety Circuits.

If "What you've got" is some odd behavior ... starting and "Neutral-related" ... you need to do some mod's to fool the safety circuits to behave normally.

Not often recommended.
But, if you are really chopped right down to brass tacks ... we'll have to set you up with the work-arounds.

 

Here's a link to some wiring diagrams:

ok, a few more direct questions. There is a wire running from the hot on the selinoid to the fuse box, which if i am right seems to feed across the fuse, then back feed the other 3 systems on fuse box, which are all wired into a common wire on one side of the fuse box? This can't be right

Also the rd/wht wire that runs out of the selinoid into a relay (along with a baby blue wire, and a black and yellow wire) it then runs out and up to the engine kill switch. Is this right?

 

The hot from the one fuse feeds into the key switch, which then back feeds through the brown common, each fuse then goes to its respective circuit 1. brake lights, 2. CDT, 3. the engine kills switch(this is the return of the wire that runs from the solenoid to the relay to the stop switch)

I dont know what the other two wires in the relay are for, Im reinstaling the harness after stripping the bike, it ran as is before dissassembly, but now the bike wont turn over, it will if i jump the solenoid, but i've used that as a key before and it gets old. I've double and triple checked all the connections and know everythings in the right place because all connections were individually labeled (i've played that game before), I'm pretty sure that I blew the relay yesterday when I did hook a couple of wires backwards (and i was jumping hot across all the fuses out of frustration), The thing is the relay is 58 buck from yahama, and I dont have the time for ebay, does this sound logical?

 

Did you check out the link flooglebinder gave ya? That's a link to the schematics, print them out, that should answer all your questions.

 

I have a complete '82 650 Maxim harness for sale it you need one. >PD<
