How do i replace headlight bulb on my fisher plow

First make sure you have a good cable feeding the solenoid battery terminal check with a test light if ok, turn the plow switch on and test both sides of the solenoid if there's battery voltage there check at the plow lift motor is it plugged in, if so check at the plow lift motor battery terminal and if it lights your light repair the motor....these motors are know for seizing or getting stuck if you take the cap off you can probably fix it, put a punch mark on the cap, barrel and end frame to ensure alignment when reassembled. I hope this helps. Take Care.

There solinoids on pump. Check wiring and grounds. Make sure all small wires are intact and in good condition. But most likely there's a loose corroded or green wire causing issue

This sounds like there may be a short on the passenger side causing the circuit to draw more amperage than it should, thus dimming the headlights. try using an amp clamp on the blinker wire at different spots to see if the amperage jumps up.

Most of the headlights do not unbolt to change bulbs. If it's a blown bulb you're trying to replace, look on the back side of the headlight housing. There should be a plug with wires attached going into the back. This plug should twist either to the right,left or up or down. Once you've twisted this plug out of the headlight housing you'll see the bulb you need to replace. Unplug the wire harness from the blown bulb and place it into the new bulb, being careful not to touch the new bulb with your bare hands as any oil or other contamination will cause these bulbs to blow as soon as they are turned on. Place the new bulb with harness back into the socket in headlight housing and twist into position.

There are "shoes" that go on the bottom of the plow so it stays up out of the stones. You will have to take them off to plow on pavement though.

YOU WILL HAVE TO GO TO FISHER. TRY TO GOOGLE FISHER AND SEE WHAT HAPPENS. THANKS MOTOR62500...

Sounds like pump is not working, check all fuild lines. Unless the plow is all electric, then the ground

I'm guessing that you have already checked to make sure there is power going to the plow lights. If not use a test light and make sure. The most likely problem is the grounds from the plow lights themselves to the frame. Take the lights apart and check and/or replace the grounds, wires inside the case take a lot of vibration and that can cause them to fail.Don't forget to check the bulbs to be sure they're good too. Hope this helps.

A poor ground. Check the ground wire inside the light housing itself and then make sure it is getting a good ground where it mounts to the plow frame. Hope this helps.
