Chuck, Gerald is correct dash gauges are for entertainment, and you know everything is working
and your wife forget to pop a bag of popcorn for the main event. I agree with Ed, look close at volt meter,
for loose connection on one side of volt meter or bad wire. If you can get at volt meter again again
check across both post. One thing a volt meter will tell you what condition your battery is in, amp gauge
will you the charging circuit is putting out. Could it been possible to have low battery for some reason
you are seeing two different readings. Dave Atherton Retired Cat Mechanic
