Outer Limits 4x4 Board

ok guys i need some my parkers keep blowing fuses. is this a comom thing or someone had this happen it was only since i go it bogged. ive check bulbs, wiring, trailer plugs conections, everything seems ok no broken wires or bad connection going to take it to auto elecs next week just wondering if someone knows thing or two that i should check that i havent before it goses. thanks chris

does it have a trailer plug? if so is the trailer plug full of mud?

do you ahve anything else running off the headlight fuse - underbody rock lights, spot lights etc?

the trailer plug is full of mud but ive pulled it apart and separated each wire and taped it up. as far as i know there isnt anything else running of the parkers. my headlights, brake lights and indicators work. thanks anyway for the help. i guess its out with the wallet on to the auto elecs

all else I can suggest is mud etc in the tail lights or parkers themselves.

what I would do next is:

-get a multimeter. a $20 k-mart one will do.
-pull out *all* the lights that run off the parker fuse, ie tail lights and parkers.
-replace the fuse with the multimeter, ie pull the fuse out, set the meter to its highest amp range (10+ amps on a decent meter, more likely 2 amps on a cheapie)
-quickly cycle the parking light switch and watch the meter. (one second on maX)
-if the meter reads any current then you have an earth leak, ie a wire has rubbed through against the chassis somewhere - start hunting, use the meter to test for continuity between the +ve side of the parking light globe holders, and the chassis.
- if the meter does not read any current, then the problem is with one or more of your globes. start replacing the globes one at a time, with the switch ON, and see what happens.

I'd do all that before taking it to an auto electrician, he will troubleshoot it similarly anyway.

good luck.
