Does the S4 use a voltage stabilizer?

Recommended Posts

My temp gauge has started to meander dependant on throttle load a smidge. I know the early cars had a voltage stabilizer to stop this that can, in time fail. Does the S4??

Wiring diagrams show one?

I can't find a stabilisor in the diagrams for the SE or S4. The regulator on the alternator should be sufficient to keep the voltage well withing working range of the (modern) instruments. You could check the actual voltage at different revs to confirm it's fluctuating or not.

I have made many mistakes in my life. Buying a multiple Lotus is not one of them.

AFAIK only Smiths gauges use a 10V regulator, but external to the alternator's.

I can only suspect an earthing problem then to affect more than one dial.
