I have my dash fascia removed whilst doing some work and the rear demister switch touched some metal andthere were some sparks. Now I have lost mfa and rev counter, clock is still working. I have checked fuse 21 and it is fine. how badly have I screwed up this time?
sounds about right, just tried the 30 second fuse pull but no joy, also noticed the handbrake light is out too so that has probably blown too. I am so f****ING ANNOYED WITH MYSELF
ah ha! 'warning lights' totally ignored that when i read the fusebox guide last night. Yes 16 has blown thanks RJ
Whats the problem when you have this fault but no blown fuse? I one of my Mk2's has a dead MFA and Rev counter, but i swapped int he other cluster and it works fine. I have read something about the voltage stabiliser or something, but can't find a lot of info about how to fix it.
this is how you test the voltage stabiliser, you find it round the back near the top passenger side of clocks screwed to a metal heatsink plate: To test the voltage stabiliser, connect a voltmeter between the terminals shown (see illustration) with a 12 volt supply to the remaining terminal. A constant voltage of 10 volts must be registered. If the voltage is above 10.5 volts or below 9.5 volts renew the voltage stabiliser. id also be checking the pcb traces carefully, make sure non have been damaged.
Hi rubjonny this is the exact same issue I have. I swapped out my voltage stabaliser for another one I have and the issue hasnt gone away. Any help would be great!
It has started working again but intermittently. Could this be a short ? I followed the red/black wire from the starter motor until it goes through the bulkhead should I be following any other wires?
if they're motometer ones this might help: https://clubgti.com/forums/index.php?threads/motometer-cluster-mfa-repair-fix-found.288785
