I own a 4 speed 1984 Pontiac. It was imported ages ago and was not used that much. Previous owner sold it to me and it was in a perfect working condition, before the sale the owner repaired everything.
I drove it for a full month every weekend, even making trips longer then 100km's.
Then all of a sudden, I was driving and the engine cut off, I lost power and I had to park on the side of the road. later that evening I picked it up and placed it in my warehouse were I could check what was going on.
so : Lights still work and so does the radio. the horn. the 4 blinkers (wich show where you want to go, I dont know the word in englisch) work the rest of the dashboard does not work what does not work : the windshiels wipers, the blinkers seperatly (left/right) starting the car the voltage meter does not work
the strange thing is, the gauges are "stuck" on the postion when I was driving (so it shows me 20km/u , and xxx rpm)
what I already tried : testing all the fuses testing the battery voltage checking the cluthcontrolswitch on the clutch pedal
So it seems no voltage is arriving on the dashboard,
can you guys help me where to look further? Is it a shotcircuit? is it the ECM? is it a cable that is loose?if so where do I have to look?
There are a set of fused links (or "fuseable" links) that are connected at the starter. On of those is likely burned out. I don't know the values (in Amperes) of those links. I'm sure that someone here knows. Perhaps they will comment.
Edit - It's possible that the link has merely "fatigued" and broken, instead of burning. You might be able to repair such a break, instead of replacing the link. Don't alter the wire length too much. The rating of the fuseable link depends upon the size and the length of the wire.
While you are under the car, look for places where wires might have burned through or rubbed through, and caused a short circuit.
Welcome to our obsession! (I always tell newcomers that.)

Here's the basic wire diagram for the power supply circuits for your '84. Find out which circuit is common with all of your problems and that will narrow down your troubleshooting. I suspect it's a problem with the many connections at the starter like Raydar said.
Thanks so much for the replys I'll get under my car soon and follow the 12volt line from the battery, it all connects to S206,C50D,5RED Fusible link A .. So i'll check these out
no it does not crank over , not a sign ,completely dead, also no lights on the dasboard...
Does anyone have a picture or a explenation where I can find that Link? I already opended up the center console so I can see the ECM but it is all good. So the hunt for link I goes on
Fusible links A & B are attached directly to the starter solenoid (which is attached to the starter motor). Fusible links E & F are attached to the alternator.
Your fusable links are (probably) still good!...the wire has worn/melted through next to the link, which is the fat part in the wire....probably on the exhaust pipe. Get that soldered and covered up quick!
