Temp In Relation To Gauge

<< < (3/3)

67FBGT:
Thanks Scollist! I will test my temp sender unit and see what's what.
Interesting the Mustang Monthly comments about the ammeter, as in being basically a fire risk. I had heard that and disconnected mine long ago as it never worked anyway. Would be nice to get it going though, maybe converted to a voltage gauge instead.

scollist:
Here is the resistance wheel I was talking about - it goes in place of the sender unit.

Unfortunately it looks like Jaycar no longer sells them though. Bummer.  I'm not sure if any of these would be an alternative - https://www.ebay.com.au/b/Resistance-Capacitance-Inductance-Decade-Boxes/183485/bn_55158878.  The other option would be to make one using a potentiometer, a piece of board to mount, and a couple of alligator clips - if you know the upper and lower resistance I'd assume that points in between when rotating would be linear (but I'm no expert here).
