Can someone with a multimeter or some knowledge help me out?
So my taillights, front parking lights and dash lights, on 1 circuit, keep blowing the fuse.
I broke out my multimeter and started checking for wires grounding.
On my fuse block, fuse #9 that keeps blowing, I have continuity to ground on 1 side which I think is correct.
right?
However, when I pulled apart the rear brakelight adapter at the rear of the truck, the brown wire (taillights) I have continuity to ground...
on BOTH sides of the plug adapter. The male and female connector when separated I register is connected to ground.
The turn signal and brake light wires have no continuity to ground and they work fine.
This is likely my problem right?
I have wires grounding in multiple spots?
If you've Gog a meter, what are you getting?

Oh, good point.
I did not unplug the harness from the bulb, that is what I coulda been reading.
Ya. I need to completely isolate the circuit and recheck, then start "hopscotching"
Til I find the issue

ok, what scale/meter are you using? is it an M on the scale? That would be 10 meg ohms, if so it is not grounded. Is the fuse blowing immediatley? If so, I'd suggest unhooking everything on the circuit, power up the curcuit, and individually plug in the electrical connectors till fuse blows. That will give the problem.
I use it every day for work.
a UEI phoenix DL289
It may be megohms, not sure.
It has an M fallowed by the ohm horse shoe thing like this: MΩ
Oh wait, no I am thinkin of milliamps.
you are right, megohms.
Sorry again. you know, the mentally handicapped thing
