Gas gauge/generator issue 1947

[fairviewfarm]

This is a strange one. I had my generator rebuilt using a re manufactured armature and NOS or NORS field coils. Now it charges well BUT I noticed when I am at higher speeds the gas gauge shows more gas than I know I have in the tank. When I slow down the gauge needle falls back down to the correct level.
Is there any relation to the rebuilt generator or not? I don't remember seeing this before I had the generator rebuilt. Also I had a new USA made voltage regulator installed prior to the generator rebuild. Any ideas are appreciated.

Hook up voltmeter and go for a drive it could be overcharging

Just because you have fitted a new voltage regulator there is no guarantee it is set correctly or working correctly. Needs to be checked by an auto electrician who understands the settings. The cut out, voltage regulator and current regulator all need to be correct. Regards, Kevin.

When I took my generator to an old school auto electric shop, the owner told me he wouldn’t do anything to the generator unless I brought in my regulator. He went on to tell me that he had too many people bring their rebuild generators back complaining that the rebuild was faulty, when in fact, the problem was the regulator.

Yes sir! A sure sign of a guy that knows what he is doing.

Thank you all. Though I had the same idea, I had nothing to back it up. I will see my rebuilder Monday and put it in his lap. I will ask him to test it. Can the voltage regulator be adjusted to reduce the charging rate?

Regulators are adjustable, that is why the gen and reg should be tested as a unit.
