Hi Everyone,
I'm having a recurring problem with my smart battery charger, GPC 45 Max. Its trying to charge 2 Trojan 6 volt batteries, T 105s , wired in series yielding 12 volts.
I have a 50 breaker wired near the + battery terminal.
All was working well until recently the breaker is popping out when 1st recharging the setup.
FYI the charger is designed for fast charging so it has high output initially, then drops off after a few hours.
The breaker is getting warm if not hot most of the time but today it popped without getting very warm.
I'm using 4 ga jumper cable wiring so that should be ok with the 10 ft run to the batteries.
The only thing I can think of is the connections to the breaker is a set screw and its mashing down on a bunch of loose wires in the jumper cable. Maybe this connection is not solid enough?
Do i need to tin the wires to make better contact?
The charger gets up to 13.77 volts then the breaker pops.
Everything is rather new in the system.
