Reverse Polarity of Batteries
This spring I brought the batteries out of the garage after winter storage and hooked them up to my hybrid trailer. There is a sticker on the front of the trailer indicating the standard red for + and black for - just like a battery charger. Immediately it was obvious something was not right, with massive sparks and the melting of the insulation on the cable between the two batteries.
I looked under the trailer and sure enough the red cable is grounded to the frame. Some of the people that build trailers are ******** or on drugs. Don't assume anything.
Now the charger shuts off and restarts every 10 seconds on shore power. The radio doesn't work. Several lights like the refrigerator don't work. I am thinking about upgrading the charger which is a single stage old Magnetek 6332 and 32 amps. Any thoughts?
