mk1 gauge problems

[Jarred]

there is a voltage regulator that controls the function of both of the gauges, it's on the back of the instrument cluster. COuld be that.

is that the bit with 3 prongs and a screw to hold it down? or am i thinking of the old corolla dashes? cant remember

[Jarred]

yep, that's the one.

I'm sure having a quick search show net a few posts with pics about it, and it's replacement etc..

[GRN_VAGN]

be carefull with the prongs, some douche didnt screw mine down before i got it, so a wire from the headunit somehow wrapped around it and when i went to pull it out it snapped the regulator off... i just swapped to spare cluster i had.

Pretty sire my old corolla has same setup :S, cant remember, been a while.

All my gauges dropped out when the voltage regulator on the alternator "died", resulting in the gauge cluster fuse blowing.

IIRC., don't think the mk 1 has a fuse as such for the cluster. The tacho and speedo are mechanical, and the lights have fuses, but I'm pretty sure the voltage reg takes care of it, instead of a fuse. (also drops voltage too, as the name would suggest.)

Ahh, thankyou Jarred
Did'nt realise MK1's ran a mechanical tacho :O

[Jarred]

ooh actually. I think I'm wrong there, just mech speedo. Tacho would just run off a signal from the coil. Sorry!

Agree that it sounds like the Voltage Regulator. Get yourself a new one (they aren't that dear from memory) and replace by removing the instrument cluster. Be careful with the printed circuit sheets as they tend to weaken with age.
