Why is boat engine blower burning out fuses ?

Question

i replace fuse, turn blower on and pops the fuse. THe ground on the swicth and the blower are tight

Answer 1

maybe you have the wrong fuse in it get a bigger one and see what happens

Answer 2

Yea as said above, check the motor and any filters. Also, my contribution is that I suggest you check the wires as much as you can because it could be shorting out, blowing out the fuse. good luck

Answer 3

The bearings are probably bad>Or need oil>Or fan shorted out>Disconnect the wires and see if the fuse blows>

Answer 4

there is too much current going through the fuse

Answer 5

the motor's pulling more amps than normal.

either something is blocking or caught in it and slowing it down, or else it's just worn out.

Answer 6

Disconnect the wire from the blower if it does not blow fuse then blower is bad if it trips then you have a short in wire. It may be easier to run new wire than to trouble shoot it. Good luck most blowes do not last a long time (2 or 3 years max)

Answer 7

Either the blower motor is bad, the wires sending current to it are corroded and causing to much resistance, or a combination of both.
