DADS50,
I attached a ground to the sender side of the gauge, but got nothing, and then tried to the sender itself, and still nothing.
Yes, I initially misunderstood the instructions, and attached the power to the F side. Could be the problem.
As concerns a previous comment about the needle. I too noticed that the needle just seems to 'flop' around. Didn't seem right, but then again, this is my first. So, I don't have anything to compare it to.
