Well at first I thought that the bilge pump on my challenger was fried due to it not coming on at all. First thing, I checked the fuse to notice it was blown, and I installed another one. Still no pump. So I removed the pump out of the holder and touched the fan, and all of a sudden it started spinning. But then it wouldn't stop unless I unplugged it. I have read that there was issues with a relay, diode, and the auto bilge switch on these things, but I cannot find any of them. Is the auto switch the black box on the other side of the pump? I seen were a lot of people are just removing the auto fuse and running it by the switch. Help me please.
