MFA Problems

[rubjonny]

yep thats the puppy, you can see the mountin screws on it, plus the clip either side that allows you to open it and reseat the pcb

Cheers. I'll take a look in a minute. If it looks OK I'll get some other clocks. Does it matter if the new clocks are 120mph rather than 140mph ones? Will the sensor be the same is what I mean?

Thanks for your help. I feel more hopeful about it now.

[rubjonny]

yeah it'll work fine

Peel, which pipe did you find disconnected on yours?

Sorry mate only just spotted this. Day off work tomorrow to do some Golf stuff so I'll post up a pic asap...

Thanks Peel. I have a feeling the speedo sensor rubjonny mentions is the most likely cause of the problem but it's good to check everything at the same time.

I've had a look and can see the sensor, which appears to be screwed in properly so I'll now have to take the clocks out and take a closer look.

I changed that on mine as well runnning out of things to change!

Also your oil temp gauge is buggered, or the wiring to it has snapped, or just a dirty connection between the 2.  The oil temp sender is the small one on the oil filter housing with a black/green wire, to test if it the sender or wire, remove the wire and earth it to the block.  If the gauge shoots to max you know its a sender issue or the connection needs cleaning up!

How do I go about earthing it to the block? I've just been out and have cleaned the connection, which was quite corroded. Just not sure how to earth it to the block now. I know I need to warm the engine up first but may as well ask the question now.

Makes me wonder if it's worth taking out the clocks at all then. If I get the oil temp working I may not bother.

just touch it to something metal, engine block, chassis etc. the battery -ve would do if it can reach!  Trouble is holding it there while you check the mfa oil temp gauge...

Exactly. May just get someone to hold it there whilst I check the MFA. So, if I still don't get a reading when the connection is on the block does that mean the wire has snapped or could it be something else?

if still nothing then you got a breeak in the wiring or a problem with the dash cluster
