Symptoms: good 15a fuse, working(barely) cigarette lighter.

So far, I figured out it could be the fusible link behind the cigarette lighter. I tore the dash apart to find it, but I couldn't.. Does anybody have a picture laying around? Google wouldn't show anything, and I wasn't able to find one. It may just be because the PO ghetto rigged the stereo/audio, but if I can restore the 12V to its full power, my compressor will thank you!!

I appreciate any and all help, guys!

 

Just what gives you the idea there is a fusible link in the lighter circuit??

It is possible it was added in 89 but why looking at the EWD for 88 there is none.

It would mean taking the dash apart to get at it to replace.

No telling what someone might have cobbled together

These lighter sockets corroded with age a good cleaning with a fitting brush might solve your issue or a new socket.

Have you read the voltage with a meter??

If anything was open you would have no voltage at all.

 

Numerous searches through this forum confirmed that there are fusible links, and they are known to blow/burn when overloaded, ie compressor, converter, etc. I wasn't questioning the cause because it seems to be pretty well documented. I just can't find the actual "fusible link".. I've been told it resembles a bit of solder, 2 wires connecting to themselves, and a little brown wire, none of which I could find.

Any other ideas?

 

Well there is no fusible link just for the lighter.

If one was open other circuits also would not work

If the fuse has voltage your fusible link is not open.

They are in the engine compartment fuse block or in line in the wire from the battery to fuse block.

Just how are you testing the voltage from the lighter socket??What voltage are you reading???

With battery voltage I have never seen any of these sockets work in these older trucks . They just corroded over the years or wear enough good connections are impossible.

Why not run a heavy duty circuit for your compressor .

It only draws 15 amps at start up.??
