[AJD] Ammeter Question

[wb5cys]

I should have said amp gauge.  The amp gauge on my tractor does not seem to 
deflect at all.  I verified that my electrical system is charging, but I 
just don't see any movement from the amp gauge.  The tractor has been 
converted to 12V and a new gauge was installed.

Is there an easy way to verify a working amp gauge?

Thanks!

Cal B.
