My 67 R60/2 is showing high voltage, ~10vdc, at the battery at revs above idle. Background...a while back the gen light starting coming on at high revs. i replaced the brushes and a local shop cleaned up the commutator (more on this below). seemed to solve the issue then the gen light started coming on at lower speeds. after some checks on charging system per the Doug Rinckes paper i decided to replace the original VR with an electronic VR. again seemed to fix the problem (maybe five mile ride) but next time out all the lights blew out (except for gen light). i checked the voltage at the battery and found about 10v. checked installation of new VR connections, all per instructions. while it seemed a long shot that the new electronic VR was a dud, Vech graciously offered to provide a second one at cost. didn't fix the issue, still high voltage at battery. voltage across the battery is 6v at idle.

Any ideas? could this be a problem in the stator field coils or in the armature? i believe the guy that checked out the armature only polished the commutator and did not turn it. the insulator sections are still below the contact surface.

Your Regulator

Your voltage regulator is either mis-wired, mis-adjusted, or just plain faulty. Since another one did the same thing, I'd be checking my wiring over very closely.

EVR

Is this what you have?

EVR

I don't have the instructions with me but....the installation is similar to that shown. four wire connection: yellow wire to field winding yellow wire originally connected to old VR, blue wire attached to 61 (positive brush), red attached to a 51\30 post, and brown wire grounded under an EVR mounting screw. The old resistor was removed per installation instructions.

Charging problem

Did you resolve your charging problem
What kind of voltage regulator are you using with the colored wires SPI ?
