Outer Limits 4x4 Board

has anyone had this in there GQ??? iv got a 88 swb on pet. only does this when cold. and then fixes its self whe the car is warm. idel is steady and not eratic. just the needle. Whats going on???

i would first: remove your cluster and check for any dry solder joints on the back of the tacho.

dunno if this is any help but my L24 powerd mk does the same thing i found it to be a loose connection in the fuse pannel..by just tapping the fuse box it rectifies its self havnt had time to fix properly tho
Cheers Bourkey

yep mine does the same thing , only now after a year it does it when its warm sometimes too

just get used to it or put an aftermarket one on the dash if its annoying ya

Could be worth checking the connections on the rear of the alternator and perhaps checking the brushes don't need changing.

Had this on my disco once, one of the leads works loose which causes it. Had a BJ40 that when that was doing it. We were heading away so I wanted to replace the brushes before going and they were just about non existent.

Fixed it

Had the same prob with mine 2.8t fitted with a 4.2 t changed the gauge and now is good.

Mine did that once when you talked on the CB as I had run my aerial lead through the same hole in the firewal as one of the wires to my after market electronic ignition. Moved the aeria through a hole on passenger side and no problems again until this summer. Erratic needle on tacho was due to a wire in vicinity of coil that was scotchlocked, had it soldered and problem went away.
