    I was just getting ready to make my intro here soon when this popped up. I have a 1993 VFR750F that I traded my old Triumph Bonneville for, its been pretty badly abused, missing side fairings, etc.

    Anyhow, on a three hour ride from Chicago to Peoria, the regulator/rectifier gave out, the gauge lights went bright right before the ignition died. I immediately pulled over and disconnected the battery, which was screaming hot, I couldn't touch the rectifier, and the ground terminal on the R/R plug was badly melted. I managed to get a good battery at cost, and overnighted a Rick's Regulator through Dennis Kirk, after that, the bike would crank, but not start. The ignition fuse was blown, and blows every time the shut off switch is switched from off to run. We pulled most of the covering off of the harness in search of burned or shorted wires and haven't found anything. Could the ICM box be the issue?

    EDIT: OK, so now everything with a plug on the harness has been disconnected, and most of the tape-wrapping has been stripped, no burned wires so far, the fuse won't pop if you unplug the ICM and switch the bike to run, but it blows as soon as the ICM is plugged in...Enough for me to buy an ebay ICM I think, are there different ICM's out there? as far as a California p/n and a 49 state p/n?

    So, any suggestions would be much appreciated, also, I found a clean looking 1992 harness on Ebay, it almost seems like it would be worth the money to eliminate one more possible problem, will a 1992 harness fit?

    Thanks, Fozzie

    Wow thats also a new one. Dang it could be, obviously its after the power is on, Doh! it could be just about anywhere, yea I know not much help, but no fear, I do have something else to think about. Did you get the new plug from Dennis Kirk too? Thats a biggie if it doesn't make good contact it will cause you trouble later on, don't ask how I know. 92 harness should work from what the shop manual says.

    Thanks for a quick reply on this. I didn't get the new plug, the old one was beyond salvaging, so I used individual spades :rolleyes: being absolutely positive that the polarity was right.
