XJ12 temp gauge with pinto water temp sender
 

Hi,

I liberated nice temperature and fuel gauges from a scrapped Jag XJ12. Any ideas how to hook up to temp gauge to the temperature sender.

I've experimented with a couple of configurations, but I either get no movement or the needle goes over to the far right.

Do I need to put in a resistor or something? Or can I get a sender which will "drive" this gauge correctly?

If it helps, the brass spade connector has at '+' symbol embossed on the plastic beside it.

I have (unscientifically) recorded the response from the pinto water temp sender. The results on a google chart are here.

This might help someone figure out how I should connect the gauge.

I used these gauges in a cobra kit that i built and i had the same grief. I have got a series jag manual here and all it shows is a live to the plus and the other wire to the sender unit. I had to get the sender unit from a Jag and re tap the hole in the yank engine to take it. The rev counter is fun and games as well, to get that to work we had to get a pulse wire from the alternator and adjust the trim screw on the gauge to calibrate , the speedo worked off a transducer so that was a ball ache too. Got round it all in the end but those budget gauges you see on ebay did look attractive in the end.
