Odd electrical gremlin

Post by Peter-S »

I took the 2.8 to Duxford yesterday and all was well getting there. Coming home, waiting in the queue to get out I realised the fuel and temp guages were not working although both gradually crept up to the bottom of each gauge. The dash charge light was also glowing and got brighter when I touched the brakes. I was thinking voltage regulator at that point. As I headed off down the road and got on to the M11 I realised that the indicators weren't working either! I was now wondering if I had any brake lights which worried me a bit so I pulled off at the first services. At the roundabout both dead guages suddenly went to the top so I tried the indicators and they worked. By the time I was parked the guages dropped to sensible readings. I did a quick check of fuses and connections, all seemed well, all lights worked so I headed home and didn't have another problem.
As everything works I don't know what to look at to save it happening another time. Any thoughts any one?

I hate electrical issues like this but as our cars are so old now anything is possible, my knowledge on auto electrics is limited but as you have checked everything that is visible then perhaps it's something you can't see:

Printed circuit on the rear of the cluster damaged in some way?
Multi-plug that goes into the cluster making a bad contact?
Corrossion on those 2 plugs that go from the engine bay into the car?

This is where I would start my search mate, good luck 👍

Hey Peter,

Just looking through our good friend, Clockwork Orange' wiring diagrams and I wonder if you gave fuse 7 a wiggle??? Could have been this looking at the diagram!!!??? We do know our fuses are a bit, erm.... erm.... yep, like that!!! :xd: :xd: :xd:

Best of luck, cheers,

John....

I've had the issue of the fuel and temp gauges reading full before, I gave the fuse board a clean up and haven't had it since

I also remember taking the car to an auto electrician many moons ago for a different problem that I couldn't solve, took him ten minutes and said I had done everything by checking the earth's and the fuses, but that the connections on the bottom of the fuse board were quite often a problem as well. He cleaned it up, dabbed an extra bit of solder on the offending fuse and voila

Thanks for the input chaps.

I shall clean stuff and hope all is well as indeed it was for 100 miles home after the problem elected to fix itself!
Using the car today and all seems fine, so long as it stays that way until the Mot that I must arrange soon.

Did you know that the run from the Jct below Duxford to the Stansted Jct, where the services are, is the longest section of motorway between Jcts in the UK. Bit ironic for you I guess.

Looks like Uncle Taff has bragging rights on this one.

Checking a couple of things this evening prior to booking an MOT I realised that the electric fan wasn't working unless the engine was running and even then it seemed a tad slow. It should run with the ignition on but wouldn't so I checked the fuses. Taking the fuse cover off the fan started running then stopped. The feed for the fan comes from fuse 7! Wiggling the fuse and the fan worked OK. I remember putting the fan on at Duxford in case I was in a queue for a long time and I guess the poor connection was drawing too much current to allow the rest of the circuit to work properly. I turned it off at some point once I was moving which is probably why everything started working again soon after.
Hopefully that is mystery solved!

It's confusing that's what it is.
According to the map the M26 is only 10 miles long in total? Joins the M25 to the M20?
However, I have found a section of the M20 that is 14 miles equalling the M11, ironically between Jct 8 & 9, same numbers as the M11.

I have discovered that distance between Junctions 1B and 2 on the M25 wins! It is well over 100 miles, travelling anticlockwise. :D

Hi Peter, it’s highly likely that you have corrosion on your fuse holders and when damp gets on them it’ll give you the issues you had. Like the others have said it should be a simple case of a clean with fine sandpaper or if it’s a dry joint (a crack on the solder) then a soldering iron will sort that out in a flash. Just make sure there isn’t any petrol leaks about ;)
