Dont laugh. I picked up one of those little Coleman solar panels for a $1 at a yard sale. Thought I would use it to top up the riding mower battery.
I put it in the sun and measured voltage at the two pin SAE connector and it showed 14 volts at the correct polarity.
I then attached the battery clip adapter via the SAE connector and measured at the clips. Same voltage but REVERSED polarity? The connectors and clips appeared to be wired correctly withe the positive side of the SAE connector going to the red clip. There is a 7.5 amp inline fuse on the positive side of the clip and fuse tests fine.
I am scratching my head how the polarity is getting flipped. HELP!
