Thread: 81 RRC voltgage

Hi Stu,

Does your meter read correctly (12-13V) if you hold the two leads directly onto the battery terminals? If not, the meter is faulty. If so, the wiring is crook (What voltage readings do "six o'clock" and "three o'clock" actually mean? Perhaps a photo of the face of the gauge would help?)

If the meter seems to be OK directly connected to the battery, the easiest fix might be to run a new twin-core cable from the battery terminals to the meter in the dash. Voltmeters should draw negligible current, so light twin-core speaker wire should be OK.

The other meter you tried - sure it wasn't an Ammeter? Ammeters present basically a dead short when connected between +12V and earth.

Thanks Ian.

Will check that and get more info.

Cheers

Finally had a chance to look at this. Yep, if I hold the gauge wires on the battery it swings from left side throughthe arc to right side. In the middle straight down is "Normal" according to the gauge.

So.... anyone have a Smiths gauge they'd like to get rid of?! Also maybe an Smiths Oil temp gauge too? (I assume they were original) or can I get away with using other gauges but using standard transmitters/ switches?

Thanks
