Look at the fuse and see if the fuse is melted of smokey blown. Smokey looking plastic is a high current overload and indicative of a shorted connection or a commutator that is having problems in the pump motor.

In the short term, you could replace a higher amperage fuse, upping it no more than about 5 amps once to see if that is sufficient or if the problem is more than that.

If you wanna unplug your pump and install a fuse and drive around for a while, youll know it there is a short. With the pump unplugged the fuse should NEVER blow/melt, just as a hint.

BTW my Johnson pump is still ok on the stock fuse..........ENJOY

Thanks, I was thinking about trying a 15 amp fuse. If the wires aren't wrapped good with tape around the connections could that be the cause if they are getting wet? I think it might be the pump itself because it has worked fine for 8+ months.
