Fuses blowing, wires melting... It has been on a parrallel circuit for my trolling motor, which at this point seems to be fried. This 24 volt system is also rigged to an onboard triple bank charger, which seems to be fine. It melted the wires for the other 12 volt system so bad it fried my Garmin.
They found the problem immediately at Wally World and said that, Excide was the ones to pay up. I called Excide but the lady I need to speak with comes in tomorrow.
I hope they pay... that stuff is expensive.
ANY TIME YOU FELLAS BUY BATTERIES, HAVE THEM CHECK POLARITY TO MAKE SURE NEGATIVE IS NEGATIVE AND POSITIVE IS POSITIVE.
Good troubleshooting.
