I have a Minnkota 4 bank charger. I've always had bank 1 extended to charge a battery in the back of the boat
For the last 3 years it was ran with 18AWG wire I supplied. Today I re ran the leads with 12 AWG hoping it would allow more amps and faster charging. I cut the old wires out and ran the new 12 AWG. Turned it on and Red light! Polarity is correct (double and triple checked), inline fuse was removed though. Could the charge sense the absence of a 30amp fuse? Would is not like the 12AWG? I'm lost now
