Thread: Fuel gauge wiring

HowStuffWorks "How Fuel Gauges Work"

there are some variations but generally you had it right in the first instance

It depends on which Landrover you are talking about.

Your description is correct for Series up to 1967. For the rest of Series production, it also applies with the complication of power coming from a voltage stabiliser that has three terminals - voltage in, voltage out, and earth. 90/110/Defender (and, I suspect, RR + Disco) have the same general description except that the voltage regulator is incorporated in the gauge, so that this is a three terminal device - voltage in, sender, and earth. A further complication is that most (all?) senders in diesels have a warning light switch incorporated.

110 v8 have the fuel level warning lamp too John.

Hmmmm o k Let`s see. It has a classic range rover instrument binnacle muonted in the dash and a classic ranger rover tank and sender. So would it have the voltage regulator built in? It is or was a petrol tank and now a diesel tank, so won`t be any diesel warning lights.
