rpm and mpg?

[turbo87]

hi guys,

recently my rpm and mpg has stopped working since i tugged a few wires under the steering column. so today i took the whole instrument cluster out and the red connector isnt there, meaning i cant find were it has gone. iv looked everywere behind the dash. can someone help me locate this cable as to were it might be or were i can trace it from.

thanks

done some browsing on the net and read that it could be the batteries can someone confirm with me that this could be the problem?

it could be the SI board batterys, if its a VDO instrument cluster these are more prone to the batterys leaking, seems a coinsidence that they stopped when you were tugging wires

i did a similar thing and my car wont start anymore

[turbo87]

do you know what type of batteries they are AA ni-cads or ni-mh. really hope its something this simple

thanks

[Alex]

dont think you can replace them, as far as i know when they go, they leak and you will need a new SI board or new cluster

[turbo87]

ahh were is the best place to get a new SI board?

The batteries can be replaced, I've done several... Assuming of course that the batteries haven't leaked and corroded the PCB.

The batteries are AA style, but with lugs on the ends for soldering into the PCB, single pin on pos end, double pin on neg end.

[turbo87]

where did you get the batteries with the lugs?

[Gortour]

Maplin will do them, or CPC, Farnell, RS...

Cost me less than a fiver for the two last time I did one.

Brian Moore gives the source of the batteries in this thread

You'll need a soldering iron if you haven't got one.
