did you try using the new sender with one gauge to see how accurate it is??? i tryied using a t fitting one time long ago and it did not work
*Funny you asked--I bought two new Datcon marine heavy duty matching temp gauges and a guarenteed compatable dual station sender from the electronic specialist in the area.
Took them to the bench, hooked them up correctly and heated the water to 185 F. both gauges registered the exact same--145 F.* I then unhooked the second gauge and presto, 185 F.* Took the sender in and asked them to make sure it was a dual station sender.* The order catalog and the company tech on the phone*confirmed*that it was indeed a dual station and was compatable with the gauges that was purchased.
Tomorrow they*are going in the boat to see how they register--just maybe the sender requires the engine block for a ground instead of a lead from a battery. (?)
I read that the sender had to be in the block with the water running around it. Guess when a tee is used the water is deadheaded and doesn't give an accurate reading. I do have a second water sender tap but it's being used for the high temp alarm--really hate to lose that.
I'll let you know what happens-thanks for all the input.
