New 3 phase voltage regualtor
I'm in the process of replacing the stock voltage rectifier on my 1982 GS750E with a new and improved unit. See the difference in fin size and wire gauge. I have pre hooked up the unit and ran the motor and everything worked. Voltage at 3,000 rpm was 13.66. Now I have to trim the wire down to fit.

The Compufire is a good unit. Be sure to run your stator wires straight into the R/R, bypassing the stock harness. Also, make sure you run the ground back to the battery and check for voltage loss along your power output wire circuit on the way to the battery. If you are losing more than .25 volt on the way to the battery you have issues there. Oh, and your system should put out 14.5 volts, or near, at 5000 rpm. Any less suggests either poor wiring or a weak stator.Ed
To measure is to know.

Hopefully you got the Compufire SERIES regulator.
They make more than one model, not all of them are the preferred series type.
(A Polaris regulator would have been a LOT cheaper.)

Doesn't matter for me now, as the Compufire has been pulled and replaced with a Polaris.

Finished the installation today, got 14.36 volts at 4000 rpm, seemed good. I read somewhere in the past that the stock system ran hot, and my 82 GS certainly has run hot in the past. Whether my oil temp gauge is accurate or not, it is certainly alarming to see the temp needle up in the 310 degree range on a warm day. So that was a major reason for the upgrade.
I took the bike on the freeway for a test ride, the weather was around 70 degrees. I rode into stop and go traffic, then when traffic cleared up I took her up to 75mph and stayed there for awhile. In the past that would have moved the temp needle to the upper portion of the gauge, but on this trip the needle stayed in the 260ish neighborhood. So far so good.1982 Suzuki GS750E

Nessim might be along to say you are mistaken and should replace the R/R to make sure you are not mistaken.
