Here’s a good thread explains it well

How to test voltage regulator/stabilizer

I need to test the voltage regulator/stabilizer in my 1970 IIA. I guess the first question is which to I have? There's a black box on the engine side of the bulkhead that clearly says "voltage regulator" but inside the dash behind the instrument panel there's something that looks like it could...

Does that just regulate the charge voltage to approx 14v but the little one behind behind the dash drops the 12v to 10v just for the fuel,and temp gauges to read accurate

Dont honestly kmow but alternator vehicles dont use the old regulator, charge goes to battery and fuse box.

Had the same problem yesterday. Checked the thermostat all ok. Refitted everything and bled the heater box. Took about 3 mins until the water started dribbling out of the pipe. It then started gushing out. Problem solved. Bad airlock. Temp now fine.
Worth a try.
