Maybe someone here knows?

I have an old Bobcat 444 that I repowered with a Briggs 23hp Vanuard engine. My question concerns the charging system. If I attach a battery tester to the battery I can watch the voltage rise as the system recharges the battery after starting. But the 30-0-30 amp ammeter I have in line doesn't show a thing for charging. It does show a slight discharge when starting. Could it be the ammeter is just too "big" for the system and that I maybe need a smaller ammeter, like 15-0-15 amps? I know on my old generator tractors if you stick a more modern 60-0-60 amp ammeter in the line it hardly registers at all, but a 20-0-20 will jump all over the place.

It's all magic to me! :oops:
 
It probably is too big.

The B&S engines came with several charging options, none are very high amp.

It could also be wired wrong. There should only be one wire on one side of the amp meter, that one coming from the battery. All the other wires, and the charge wire from the engine should be on the other side of the amp meter.

If I were going to make a change, I would replace the amp meter with a volt meter.

That would involve tying all the wires on the amp meter together. Then come off the ignition side of the switch to power the volt meter.
