Ordered a new regulator from rmstator, Not sure of the quality of the item. I have aftermarket exhaust, so thinking stock location is ok at present. Been studying the wiring diagrams on whats been stated as per the coil rewire, and think I will do the same. Seems like the weak point would be the ignition contacts. considering the only other thing ran off this is the starter switch which basically just controls another relay contact.
Question on R/R mod wiring, One of the wires to it is a ground, the other seems to be hot with key on power, and the white one is 12 volt all the time, Im assuming you are grounding the black wire from the R/R directly to the battery, and the white wire are you disconnecting it and goin directly to the positive or are you splicing into it, I assume looking at the wiring it gets 12 volts from the fuse box. so it wouldn't be needed, so adding a 30 amp fuse inline at the battery with this wire gives it direct charge from the R/R. In the process of building a couple of stainless coasters to do away with the emmissions. Bike is a 91 750 my son purchased, ran but ran poorly, only has 5000 miles on it and he got it for 800 bucks, weve done a few things to it so far, have it running pretty well, but noticed the new battery seemed to be getting weaker, found the r/r to be corroded on its terminals and the plug looked melted, cleaned them up and the charging increased slightly, so decided to just replace it and ad a new connector and rewire directly to battery. I assume the key on power wire is needed to energize the R/R. kind of wish we would have seen this new updated mosfet set up before I ordered the new regulator. may just have to do it later.
