Thread: Flathead dual temp sender-good idea?

Tweet

A better idea. Individual senders in the heads, wired to a two way toggle switch and then from the two way to the gauge. I have this in my T with a flathead. Works real good. This way, all you do is flip the switch to see each heads' temp.

Yes, I have reccomended that and it seems to not be good enough for most, I thought it was pretty good, but I guess you can't please them all

I like the idea. Once you've determined which cylinder bank runs hotter than the other, make that the "default" selection on the switch, and then check the cooler running side as needed.

Two senders hooked to one dial gives the reading for the hottest head, not an average of the two.

That would constitute resistance in a parallel circuit, right? When resistors are connected in parallel their combined resistance is less than any of the individual resistances. Since electrical temp gauges measure voltage, the reading wouldn't accurately represent either side.

Read the reply - not two senders to one gauge - run the wires to a toggle switch and ten to the gauge. it reads one side at a time.
