OK. It ain't a slant six. But there are some really knowledgeable automotive folks here!

I'm working on a 1956 Western States Fire Engine. It has an American Bosch Generator and Regulator on it. The PN of the Regulator is RGR 1960 E115

Does anybody have the specs for the regulator? I need the gaps and procedure for getting it set up. As soon as it loads, voltage goes to 22 volts, and it pegs the test bench out. The bench reads up to 120 Amps. The Regulator is supposed to run at 15 VDC @ 60 amps.

Any help appreciated!
