Check generator

Postby AZ Gary » Sat Dec 05, 2020 7:19 pm

I have a 61 cub with a 6 V charging system. The ammeter doesn't show any movement, when the tractor is running. How do I determine the generator and regulator are working properly, or maybe it is the ammeter meter that doesn't work.
Thanks in advance

You could try using a volt meter and check volts on the battery + and - with it off and see if the volts are higher while its running

I like this tester/ meter. It checks the battery and the charging system and is easy to read.

Here is a post on how to use a voltmeter to go through your system

If your battery is charged the ammeter will read 0. Turn on your lights with the engine off the meter should go negative. let is sit for a bit. Start the cub and turn the lights on to see if it charges.
