bilge pump blowing fuses?
one of my bilge pumps keeps blowing fuses when the switch is in the automatic mode. the on mode its doesn blow the fuse but doesn't work either. How can I determine if the fault is in the switch, ground or positive leads?
96.5% of all electrical problems on board boats are caused by corrosion/loose connections. Wiring inspection every couple-three years is a real good idea, more often in salt water.
Only thing you can rule out from your description, is the pump ground wire must be ok.
Possible you have two problems -- a faulty helm switch, *and*, a faulty or blocked pump *or* direct short to ground in the pump wiring.
If you want to do your own boat maintenance, an autoranging digital multimeter is a real handy tool, walmart has one for $25 -- not the best, but good enough.
Kilo is steering you in the right direction -- you just have to methodically take components out of the circuit until it works -- except don't take the fuse out the circuit -- if it *is* a direct short to ground, you'll be looking at melting insulation with fire not too far behind.
If changing fuses while troubleshooting gets to be too tedious, you might find it convenient to temporarily bypass the fuse with a manual reset circuit breaker (two, maybe three amps, tops). Should be able to find 'em at a car parts store.
