That's a good sign, I'd say. Have the vendor send you a replacement for the one that is defective.

Well hopefully that problem is fixed. Unfortunately the quality of aftermarket parts for these trucks is marginal at best.

Have read the solid state 12 volt Bosch regulator units for a '72 VW work (for 12 volts obviously)

Good catch! I should never try to think or type before coffee! It is only a generator cutout. I think I was getting ahead of myself when I was talking about hiding it somewhere.

It sounded like a good idea

This should be my last question on the generator/regulator issue. Does the paint need to be scraped off of the firewall where the voltage regulator is attached so there is bare metal-to-metal contact for grounding purposes?

It needs good ground, yes. There is probably already a separate ground wire from the battery that is attached to the regulator to ensure this. Voltage regulators get confused without a good solid ground reference, or high resistance, corroded connections.

Best to check voltage output at the battery at 1500 RPM, you'll want to see between 14 and 15 bolts, depending on temperature. Then turn on the headlights and heater blower and measure again. Voltage will sag a bit but it should hang in there above 14
