Thanks for the correction Bobn1957. I meant amps as in the flow of current rather than force.
Last weekend I hooked up a battery charger/tender to problem discharged chassis battery for 6 hrs then disconnected it for 4 hrs. The separate multimeter read 12.8 amps. Will continue to monitor the battery each week w/o cranking the engine to assure me it is indeed holding a sufficient charge.
After fully charging chassis battery a couple of times I checked and now battery is consistently reading only 12.0 volts. Looks like I will be changing out all batteries next year.
