That's what I thought. If it's not hooked up, pump has no power. If I ground it to anything ( body, chassis, even pump bolt ) blows the fuse instantlyI think that is a ground stud, but then you shouldn't have voltage on it that would blow fuses. Maybe there's a short in the harness. What happens if you just tape it off?
Started raining and snowing hard so I called it for the day to go plow. If it's not hooked up, pump has no power. If I ground it to anything ( body, chassis, even pump bolt ) blows the fuse instantly. Something funny's going on, considered just running a separate relay and toggle switch to the pump bypassing the skid harness wiring and calling it a daycould be positve check with a probe
Aftermarket pump not oem but everything looks near the same. I kinda thought about it being miswired. Need to try and disassemble the pump wiring and see what the deal isyou say that the pumps are some what different are you sure that it is the correct pump ? If so the only thing I can think of is a bad or factory miswired motor ( like polarity reversed) or harness is in a reversed condition.
Harness is 1 red, 1 black, then 1 black that went to the ground stud on the old. I tried ground that black wire to other grounds. Not touching it with the redu blowing fuse cause u touching red with ground
