2182 charging problems ?

[John Halper]

I have a 2182 that has never showed any problems. Went to start, and nothing. Put a voltmeter on battery & only 8 volts. Has only sat for a week. Put another battery in & it started up just as always. Put voltmeter on battery & it's jumping up & down. Not steady at all. As high as 18 volts. Where to look first & how to check?

Are you using a digital volt meter? If so, try an analog meter instead. Some digitals won't provide a true reading in these systems.

Starting at the battery check for bad grounds.
