Combo Oil and Temp Guage.

[peter t]

Hi,

  All excited and ready to go for a drive and now the oil/temp guage is not working. I checked the book and it states that if this happens the voltge regulator is not working. Checked fuses and power to senders/switches and bought new oil switch but no go.

 

Any answers will be greatly appreciated.

So both functions don't work and all other gauges are ok? have you tried grounding the temp wire (yellow one where the thermostat lives) by unplugging and grounding, then switch on the ignition? It should go all the way to hot if all is well.

I have no power at all at the oil switch and intermittent power at the temp sender. All fuses are OK and fusible links are OK. Alternator is new rebuilt but may need checking. May have to check power output of alternator tomorrow.

      I grounded the temp wire as you indicated and both guages go all the way with ignition switched on but drop back to zero when started after repluging the wire to temp sender.

Does anyone know what this is. It is located  on the relay mount under bonnet.

dont mean to state the obvious peter... but im pretty sure what you've got there is a flux capacitor?? otherwise known as your external voltage regulator

Thanks Benny, it just didn,t look like what I am use to or what is in the book.

i dont think that its the original but it is a suitable replacement item!! If its stuffed here are some from the MSA site-

Check there is no corrosion around and in the temp sender in the thermostat housing. Its a pain to remove, but good to clean as it grounds through the housing. Can you get another oil pressure unit to test?

Hi Peter. The voltage regulator they refer to in the manual is actually internal to the gauge.

Try doing a swap if you have a spare. Mine went a couple of weeks ago.

[peter t]

Think I have it sorted. Both guages go to full when earthed so that would indicate the guage is ok. Swaped guages with spare and the same thing happens. Put new oil sender in and no better. Tried to get temp sender out and it would not budge. Finally broke it off and got it out with and easyout. So much corrosion I very much doubt there was an earth. Now I have to wait untill next week for a new one. Will keep you posted on the out come when part arrives.
