Hey guys. I have this problem (well alot of them
). But this one in particular is really bothering me. And would like to figure it out. Like the title says my gauge cluster is acting wacky. Just to make it easier/diagnose these are what each of the gauges are doing:
Engine Temp: Doesn't work 99% of the time but once in a great while it will come on for a short while
Fuel Gauge: Always reads full; awhile ago it used to read fine down to 1/4...
Clock: I can only remember this working when i first got the jeep, ever since it just doesn't work.
Oil Pressure: This seems inaccurate, only because it moves around even while not touching the gas. It will go from 40-60 just at idle.
Voltage: This is the only gauge I really trust. It seems to work as normal.
I have tried testing certain things, but i really don't know where to start or what to test to make this easier to figure out.
The following things I have tried:
I test the plug for the gauges with the following results:
Pin #1-Purple-Not Sure
2-White/Black (2wires)- Power
3-Black-Ground
4-Lt Brown/Black-Not Sure
5-White/Black-Power
6-Lt Blue/Green-Ground
7-Pink-Not Sure
8-NONE
9-NONE
10-Orange/Black-Ground
11-NONE
12-Orange/Black-Ground
Those where all tested with a circuit tester and test light...
Also I checked out the plug going to the temperature sensor, it wasn't getting power, but had a ground.
Also I tested the grounds on the engine and for the fuse box in the engine compartment. Good.
I tested them by attaching the power end to the battery and touch the grounds with the tip to see if they light up. Is that the correct way of testing?
Any help would be greatly appreciated
PS: I probally should have added that its 91' 4.0L YJ...
