I wouldn't have thought so, Chris. Pretty sure the sender is rheostat based, so putting 24 volts through a 12v sender would give incorrect resistance readings to the gauge. Resistance being equal to volts divided by current.my fuel gauge is playing up, the reading keeps going up and down and generally settles on near full, as the wolf is 24 volt is it a standard defender sender unit to replace.
Thanks
Chris
I'm no electrical expert mind, Chris.Thanks, I need to track down a new sender, may be I will find one at Newbury landrover day tomorrow.
I think rheostats are designed to try and keep the current constant. So, I would have thought if the voltage was different it would create values the gauge wasn't calibrated for. @Kwakerman might be able to shed some light on it.I went to Newbury Land Rover show to day and I asked several military people there, some said 12v and some said 24v, one guy told me to see if I could get a number of the fuel sender unit and he would tell me what it was. One man there who had military vehicles said you will be told you need 24v but a 12v will be fine, all confusing really. I did buy a very nice military tool kit though.
