Intermittant voltage gauge issue

[Sunnysidebb]

My standard voltage gauge has developed a fault. It reads about 10v for a while after starting, about 5 minutes, then jumps to the correct spot for about 13 volts. Ive checked the actual voltage and its spot on all the time
Any one else had similar issues?

I had that some time back as i use the Weber Marelli 145 amp alternator which doesnt fit in place like oe one and i had to adjust the tension of the belt to get it work properly..maybe it is just slipping belt like mine was..

Fuse box can make this problem, have seen this before

Thanks. Sound advice but the voltage using a meter was spot on all the time.

The dreaded fuse box, theres an idea. Not a nice one though.. I will have to drop it down and wiggle a few wires, which to any one else would look like a good kicking.
Thanks.

Any one else had the same issue traced back to the fuse box?

Power feed to voltmeter comes directly from relay 4 and fuse 2 in fuse boks.

Excellent. That should make it a bit easier. Will go straight to that and have a play.
Thanks.
