No charging after 100 miles on new Compufire
So, as I commented in the Compufire install thread. I got my new Compufire unit last thursday. I was replacing an OEM unit that had killed a battery and was charging at 17.25 volts and climbing. I instinctibly assume that the stator was good judging by a high voltage dc output from the r/r.
Installed the new Compufire unit. Solder spade conectors to the stator and r/r wires. connected them. Cut the positive and ground wires from the r/r and connected them directly to the battery. All other connections were left intact, just cleaned up.
Installed a new battery, fired up the bike. 1100 rpm and 12.8 volts. anything over 2500 rpm 14.8 volts steady.
Yesterday went for a ride. The bike was running great. I did noticed that after 4000 rpm there was a tingling vibration felt through the entire bike that was never there before, but the bike was pulling really good and the voltage was holding steady.
After 100 miles, the voltage dropped to 12 (I intalled a car voltmeter ground to chassis and Pos to the coil relay 12 volt output. I stopped to check my connections and there was nothing wrong. Started up the bike and the voltage went up to just under 13 volts, for a few minutes and dropped to 12 again. Got home after riding another 20 some miles. This morning, I started the bike and went up to 14.8 volts. A few minutes later shot up to 15.8 and back down to 12.
Checked the stator, and there is about 1 ohm between leads, but it is also shorted to ground. Could I have caused this by somehow intalling the new R./R incorrectly (which I did not do)?
I hope I did not ruin the new r/r (after $200 and three week wait that would be a bummer). How can a Stator that has been running strong for so long, fail like this? Usually is the stator that fries r/r's and not the other way arround. Where is the logic here?
Thanks in advance guys.

Sorry.. Carry on! BTW, reading that again, you really should run an inline fuse between the R/R and the battery on the positive side..
