I had a friend who loved to spout E=MC2 theory about uncomplicated problems in his anchored 65' motor yacht. After enduring yet another rave about why his widely spaced parallel connected battery bank was misperforming, I connected my AUTOMETER 1000 amp carbon pile load tester to the end bussbar and cranked it up to 400 amps.
"Yahhhhhh! SMOKE!" he yelled.
As he raced past me, fire extinguisher in hand I yelled after him. "And there, is your problem"
For the next year or so before I moved away, I heard not one more peep about ground loops, and charger peak inverse voltages.
So, it's Take Your Pick
Discover a weak battery today and then allow time to deal with it comfortably
Or do Breakdown Maintenance at 200% the cost.
