So my buddy did a frame swap, put the engine from an 83 xs650 Heritage Special into the frame from a 76. When he bought them the 83 was running, but being mechanically inclined he rebuilt the top end and installed the engine in the frame. He has no electrical experience and was busy so here the project sat, for 2 years in a family members garage.
Fast forward to now. I have a decent electrical background, but have just started dabbling in and riding motorcycles for just over a year. Both harnesses were sitting in a 5 gallon bucket with switches and "everything else." After about 4 hours with a multimeter and wiring diagrams I know what just about all of the wires on the harness are and have them with the proper electrical components.
I've done a lot of searching and figured out a couple of things but am completely at a loss with his coils. There are supposed to be 2 wires that connect to the main harness, but there is only 1 wire with a stripped end and no connector. I looked over both the coils and the splice points, to the wiring going to the breaker points, to see if there was a spot were a wire had been pulled out but I see nothing. Does anyone know where this wire should be coming from, or anything to point me in a direction? I will post pictures after this, they are on my phone and it isn't wanting to transfer to my computer.
Also the starter relay seems to be mia, he has a starter relay for a Harley but it is only a 3 post relay and this model uses a 4 post. Tried searching for the internal resistance of a stock relay but haven't been able to find it anywhere, would someone happen to know or be able to check the resistance? I could just solder a resistor on a wire and attach that on the start button post but I need to know the resistance.
He also wants to do a harness reduction/electrical minimization, but that can be addressed later getting the bike running is a first priority.
Any and all help/guidance is appreciated as I am currently lost in the sauce.
