Rex has a electrical Gremilin and I'm looking for ideas

So the oil light flickers and dings while the rpms needle drops. My engine RPM does not change--not loss of power. Occasionally the airbag light comes on at the same time. Occasionally all the dash lights flicker. It comes and goes. Maybe correlates to bumps but intermittently.

I've checked all the obvious connections (computer, harness, etc). All tight.

BTW Rex has a 5.7 AEV conversion.

I'm looking for ideas I can check. Thanks.

Shootin' in the dark here, but I'd chase down every ground, suspecting one is getting intermittent.

With the beatings you've put on Rex, the inertia of a wire might have been enough to fatigue one of its ends.

All I got. Sorry. Best of luck.

Why delay the inevitable?

I would check the lines going to the dash. If the motor is operating correctly but the dash is all hokey, could have messed up a connection there?

I think it is a ground. I checked everything in engine compartment, nothing made a difference.

I reach up inside the dash and moved/wiggled whatever I could reach. I must have bumped whatever enough to get it to stop. (For now).


Allan, I'll get rid of the jk crap soon.

I agree with others that a ground lug or wire is the most likely culprit.

Check the grounding terminals under the driver side dash near the clutch pedal. I've accidentally caught my boot on them before. Maybe you done the same thing and not realized it.

It sounds like you might have found it, but just in case.....

The main block ground on the 5.7 is located down by the starter, near where the oil dipstick tube is located. This ground is prone to corrosion (iron block). Remove the bolt and go at it with a 1/2" round wire brush (a plumber's wire brush used for cleaning copper pipe prior to soldering works well). Clean the ground lug as well. This is one of your main grounds to the 5.7.

Thanks Don. I'll go do it. I didn't really get it figured out. I just wiggled whatever I could in the dash. It was OK yesterday. This morning as I came off the freeway it dinged again.

Yes but intermittent. I don't have confidence in any correlation.

What are you thinking?

I still think its a loose connection in the wiring going up to the dash.

Just for fun, try taking it to the dealer. See what they have to say, and ask em if the warranty will cover it

I am pretty sure the dealer is well aware of Rex and closes the second he enters the lot

Pretty much! They like to get it and park it out front poser position. Work on it? Not so much.

I checked the main ground. It's good.

I am still getting the occasional ding. Now it does seem to correlate with occasional left turns and occasional bump. If I move wires around in the dash, then it changes the timing and occasion of dings. So an intermittent ground seems to be the culprit. But alas, I can't find it.

How does one turn off the ding? I'll gov look it up.

Update.



Fingers crossed. I found a ground wire in the front passenger fender that wasn't attached to anything. After reattaching, no more BS. So far. I hope, I hope, I hope….



(The dinging makes me crazy).





Edit update. Finally got it!..

A wire had broken and fell down inside the fender. It was hanging, bouncing around. Finally!!!!
