Title: temperature gauge wiring Post by: FC229 on February 28, 2011, 09:15:14 PM Hi All,
I have a VDO temp gauge and sender I would like to fit to the wagon. It has a 2 pin connection, one marked B and 1 marked S....(sensor??) Can anyone tell me what to connect to the sender / sensor, and what the other goes to? The Gauge I have currently has 1 power, 1 to the sensor, and 1 earth. I can only assume the gauge earths through it's mounting. If anyone has something similar and can point me in the right direction I would be most appreciative, not sure if trial and error could wreck the gauge?? David.

If there are only two pins, I would assume earth is through the gauge body. S for sender and the B for power, not sure what B would actually stand for though ??? Title: Re: temperature gauge wiring Post by: newman on February 28, 2011, 10:26:42 PM Battery ??? can't think of any thing else.

Only two pins needed, as suggested one to battery +ve, one to sensor, sensor body is earthed. There's your circuit. If it's VDO then they typically use a 30ohm sensor. Unusual for it not to have a backlight though?

The sensor limits the current through the gauge.
