MEP 003A

Battery volt meter does not work. Less then 3 volts on wire to volt meter with generator running. Batteries appear to be charging. Any thoughts, recommendations would be appreciated.

If you only have 3 volts on the wire to the meter, what would you expect to see on the meter? The meter can only read what is coming to it. 3 volts is not enough to make it read.

How do you know that the batteries are charging? Have you tested them? How? Have you charged them up? I would take the batters out, and load test them. If you do not have the test equipment to do that, take them to someone who can. Then you KNOW the batteries are good. Then install them, start the set up and see what you read on the charging circuit. On start up. A few min later.

Also, please change your location to the state you live in. Thanks.

My point in noting the voltage to the meter is to let folks know the problem is low/no voltage to the meter. It's obvious three volts won't move a twenty-four volt meter .
The batteries are charging because I use the generator every seven days to run an irrigation pump. They keep starting the generator for months on end; ergo, they must be charging.

The answer I'm looking for is why do I have low voltage to the voltmeter?

I would start by performing the test in the Sticky section: MEP-002a and MEP-003a DC Charging System Test

It may have been charging properly in the past & up until recently, but things do fail suddenly. Just good practice to eliminate that as a source of any issues first.

You could have low voltage because of a loose or broken wire.

Do you have the schematics and know how to follow them?
