Temp gauge problem fixed

Hi all,

Thought I would fill you in on the latest in my long running temp guage problem (see my preious posts on this topic). If you find your temp gauge is erratic this may be of interest. It's a bit long winded so bear with me.......

About 18 months ago the temp gauge on my 145QV started behaving erratically, the reading would often go up if you turned the headlights on for instance. It was looked at by an Alfa specialist who could find nothing wrong and said it must be the instrument cluster (300+) eek! I could not afford this and could not find a second hand one, so lived with the problem. It came and went and was worse in the summer (dry weather).

In the autumn the alternator started playing up, so a new (recon) was fitted (after a four week wait ). However after this was fitted the car was still not holding charge and not starting well. I was having to charge it overnight regularly. At the saem time I was driving round with the tempo gauge off the top of scale once the car warmed up.

The problem was eventually traced to a bad connection on the earth strap at the gearbox end. This was so bad that the strap was very hot to the touch. Once this was sorted she started beautifully and has been great ever since. It also fixed the temp gauge problem .

So, if your temp guage starts behaving strangely, it may be the start of a problem with earth strap connections.

Apologies for going on, but thought you may find this of interest!!!!!

I would have thought that this was good advice for anyone with an Italian car - every electrical fault that I've had so far with my car has been either dirty connectors or poor wiring / earthing wink

the only pain in the neck is having to hunt the damn things down....

cheers for that
