Hey guys and gals. I've been working on my friends 2007 big bear IRS. Unfortunately after 3 different people got their hands on it and only made things worse every time. After months of finding just crazy problems everywhere. I'm finally at the point we're its almost 100% !!! But I'm getting a short somewhere between the 4xW switch I believe. I managed to by searching the internet like a fiend, got my hands on an official Yamaha wire harness for the year and make. But I don't have the numbered component list and to be honest. After hours of going through and making everything so it's easy to reference. If anyone has a picture of the referenced components. I would be forever in your debt. I've spent hours marking up the blown up diagram so it will be easy, for any possible future repairs. Please and thank you. Here's a picture of what i have so far. Unsealed it in plastic so oil and crap won't spill or get smudged. This damn things worth it's weight in gold. Thanks Jeff 2007 Yamaha big bear 400 IRS. YFM40FBW

Background,
This winter (Dec.) I was plowing and everything just died, just quit. No lights, no pull start, No nothing. I've had this problem before and I changed the voltage reg and it ran fine for over a year. Then this. So I changed it again, thinking this was the same problem. Tried to start it and a small pin hole in the CDI appeared with electrical smoke.
Months go by and I finally decide to just replace parts (I'm Horrible at electrical issues). I changed the stator, new CDI, new Voltage reg, new starter solenoid, tested the starter (prefect), charged the battery.
Went to start it and the solenoid rapidly clicked. All the dash lights on, headlights work. Pull stared it and it fired right up no issues. Looked into the rapidly clicking starter solenoid and it was not enough juice in the battery. Took the battery completely out and hooked up a jump box to it turned the key, light on, everything looks good. Pushed the starter button and it fired right up ran great. Turned it off to test it again, Turned the key and nothing. No dash lights nothing. Took the jump box off and pulled started it. Started it right up. Re-hooked the jump box, still nothing.
Any Ideas?
