Do these fuse links tend to be covered up? ie under the plastic wiringing loom covers. When you say small tootsie rolls, bigger in diameter than 2mm.  I'm having trouble seeing any Tootsie rolls under my hood. [/QUOTE]

They look like wire, and do tend to get wrapped in the harness with everything else. Usually they are short, maybe 6 inches long, with a crimped connector on each end.

I'll see if I can get a shot of one for you tommorrow, and post it here. They can sometimes be a little farther up in the harness, so some untaping might be needed.
I think I have wiring diag. for '78, so I'll check it, also, for locations.

Thanks heap for your help guys. It's been frustrating, I've been hanging out to get it back together so I can drive it, it's been a long time.

Here's a couple of fuse-links.

Drivers side, looking down to the outside of the master cyl.


Top of firewall, right next to the windshield wiper motor.

You'll notice, in the first pic., a wad of 'lectrical tape on one of the wires. This is where someone has removed a fuse-link, and spliced the wires back together. (red wire-to-yellow) The big, black "blob"(tootsie-roll) to the lower right of that is a fuse-link.(red wire/orange wire) This may be where your blown link(s) are.
The second pic. is two links, just to the pass. side of the wiper motor.
There are more of these comming up from the starter, but I don't have a car in the air to get pics of those, but they will look just like these. Happy Hunting! Adams' Apple38697.8204398148

Thanks for those photos

I have definitely not seen any of those Tootsie Rolls on my Vette. They sorta stand out dont they. Next weekend I'll have a better look in the engine bay and may unwrap a few engine bay looms to see what I can find before I go removing my dash again.

I was thinking back to how I could have stuffed this part of the circuit. Do you think the head light switch and immediately associated wiring would have anything to do with those circuits? (heater fuse and turn sig) I replaced the headlight switch cos I stuffed my original one (vacuum and switch) as I found out when I put it back together, I had a little smoke come out from the headlight swicth/connector area. The old swich was pretty beat up to begin with.

The only other thing I think I shorted a while back was the cigarette lighter 12v cable onto a metal frame which supports the centre console. I have since insulated that cable while working.

One other thing, should I have got 14 odd volts from the solarnoid, when I measured it the other day? Is this just an effect of the internals of the solarnoid. Dont forget you are talking to a relative novice here. That may have been a stupid question

I am now an expert at removing the seats, centre console, dashboard, carpets and installing heat shielding etc and putting them back again. Though expert might be a bit much considering I created some electrical issue as a result Oh well

Thanks again for your help guys. Until next weekend.

Cheers

The headlight switch shouldn't have any effect on the heater or turn sig. circuit.

There should be 12.5(avg)volts at the starter solenoid, unless the engine is running. Then you should have around 13-14.5v.

The shorted cig. lighter could be the cause of the blown fuse-link. Does it work now, or not?
I need to get the wiring diag. to see whats what on your year. I'll check that out...

I've just ordered a laminated wiring diagram for my records and use but that probably wont be here for a few weeks knowing the post, and it's nearly Christmas.

My engine wasn't running when I got 14 volts on the solarnoid, I only noticed it cos it was high. I'm pretty sure I had my multimeter on the right setting. I'll check that cig lighter voltage again to see if it is still there, I haven't done since pulled it apart.

At least this is all practice leading up to maybe one day fully restoring one. I'll need a bigger garage for that though.
