(*^%%&$)&^^%$#&%&*(%)#7^ hate wiring!!

Well ok I cut into the wiring today to see what I could find and this is what I found..
At the switch the blue/red wire has juice

After tracing that wire as far as I could in to the harness all the while checking to see if it had power and it dose so.
At the plug I checked the blue/red wire

No power I trached this wire back in to the harness a ways and found this

these are all blue/red striped wires all tied together no power..
Any idea's at all?

 

[TexasNomad]

Well I don't know what I should do now maybe just splice in to anotherr wire?

 

[smokey]

That is exactly what I was thinking about posting. It would be best to find the problem area.

 

[TexasNomad]

ya I know but its some place deep in the dash harness some place when I opened on the harness I started finding lots of cut wires that I couldn't find the other side of So I think who ever owned this truck before me was doctor Von hack Oooslash..

Well if your finding lots of cut wires, then it might be a good idea to get in there and see what the heck is really goin on. Might be benifical in the long run, dont want to get your truck just how you like it, then it burn down in an electrical fire...

What year truck are you working on?
That dimmer wire when it leaves the head light switch goes to the fuse box. There it goes through a fuse and goes to all the dash Illumination.
If the ash tray light works then the fuse on the blue wire with a red stripe is good.

 

[TexasNomad]

No the ash tray light isn't getting power but the fuse is good....

Proven power on both side of it then?

 

[TexasNomad]

Yes I've test both sides of the fuse and it has juice.

 

[subford]

I will ask again then.
What year truck are you working on?

 

[TexasNomad]

Its a 79 f150

Well after more digging in to my harness I can't find whats the problem it makes no sense to me I can't find any where were the wire is broke cut bad brittle nothing the power just ends....... So i'm gonna just splice in to and get this thing up and running .

Sounds like a plan to me. Good Luck.

I'm having a tad of trouble here and there determining where things are at so I'm going to ask a ? based on one of my earlier posts. Did you ever check for continuity between the dimmer switch and the cluster and are the cluster lights grounded? And the light on the heater controls, does the brightness vary with the dimmer switch?

*If I understand things, I *think* you've got power to and after the dimmer switch and what I've just noted has not been confirmed.

I have read several posts that a similar problem turned out to be a bad connection on the back of the fuse box. The fuse had power on both ends but the wire coming off the back had none.

The diagram just above does not show this circuit but the one above it does.

ya the dimmer switch is good I took the one out of my blue truck and put it in there and same thing no gauge lights.. I've fallowed that wire all over the damn place under dash out side the dash and I can't what could be the source of the issue..

 

[TexasNomad]

Ok if i'm reading that right it shows two blue/red striped wires going/coming out of the Instruments plug mine only has one blue/red striped wire going to the Instruments plug...
