Hi all,
Anybody know (or would be willing to measure), the resistance, in ohms, of the temp sending unit for a '66 - 289?
With the connection to the gauge removed, mine measures 195 ohm's from the negative side of the battery to the top connection point of the sender, and also 195 ohm's from the bottom of the sender itself to the connection point at the top.
In other words, I am checking the sender two ways. - (1) the complete circuit from the top of the sender back to the negative side of the battery (which tells me the engine is grounded properly) and (2) the sender itself. In both checks, the resistance I get is 195 ohms.
Wondering if that is a correct resistance value - is my sensor good? I looked in the shop manual, and can't see any reference to what the resistance should be.
The measurement's are done at about 70 degree's.
THANKS, Dave
