......Update
The steering column's taken abit of a back seat this week as I've been sorting out my workshop.
I had the roof replaced the other week as it leaked like a sieve, and so FINALLY I've been able to sort out
a work bench and some shelving etc. inside and get the rest of my tools, paints and spares etc. out from storage.
At last, a retreat I can finally - well - retreat too
The other reason the steering column has taken a back seat is because we need to get the paint matched for it.
So because of this.... we started on the dash instead
This was something else that needed a good sort out.
When in the car, the only thing that worked was the Ammeter
After stripping it apart we briefly put a live feed direct to the other 2 gauges, and hey presto, they worked a treat
Temp and fuel both started to go straight to the full / hot positions, so there's nowt wrong with them
So, why didn't they work while in the car all wired up
Well I guess the fuel gauge was simple........the tank was empty
This doesn't explain though why the temperature gauge, oil light or turn signals didn't function
So our little investigation continued......
The little voltage regulator on the rear proved to be good, as did all the bulb holders and bulbs.
So a check of the circuit board was done, which proved to be where the problem lied........
After giving us the run around for a while, we ended up testing sections at a time for continuety.
It showed up that all the faults were in roughly the same area under the black coating.
After rubbing it away we found a series of hairline cracks across the copper routing.
1 route had a section missing of approx 1mm. No wonder nothing worked!!
There was no visible damage to the board at all. No warpage. No scratch marks or anything like that.
Haven't a clue
Do any of you guys have any ideas???
Have you ever had this problem with yours before?
Was it a problem on these circuit boards of these years?
Anyway, after warming up the soldering iron, we did the repair.
After more continuity tests, all circuits proved to work fine.
After cleaning up the outer casing, and a few coats of paint dabbed over the solder for protection, she's good to go
To Be Continued......
