I recently installed a new temperature gauge on my 1845 skid loader. Upon turning the key, the gauge immediately moves up to the bottom line. However, when I connect the ground wire as instructed, it maxes out. I'm curious if the gauge may already be grounded in the panel or if there's something I'm overlooking. The gauge features three terminals – one for the sender wire, one for the hot wire, and one for the ground wire. Any assistance would be greatly appreciated. Thank you, Norm.
Have you tested the sending unit to ensure its functionality? You can refer to a table in the manual or search online to find the recommended ohms readings for different ambient temperatures (best to check when the engine is cold). It is possible that the sending unit or its wire may be either open or shorted.
Disconnect the sender wire and connect the ground wire instead. If the gauge does not show any movement, it could indicate a faulty sender or a wire short circuit. Remember to troubleshoot both the sender and the wire for accurate diagnosis. Steve
I will inspect the sender to ensure it is functioning properly with all-new wiring. Thank you, Norm.
The temperature gauge is now functioning properly without the need for a ground wire. It seems that the gauge is grounding itself when installed in the housing. If it had a rubber seal, the ground wire would be necessary. With a new sender, new wiring, and the new gauge, everything seems to be working smoothly. Thank you, Norm.
Answer: Answer: The issue could be due to the gauge already being grounded in the panel or a potential grounding issue within the wiring system.
Answer: Answer: The three terminals typically include one for the sender wire, one for the hot wire, and one for the ground wire.
Answer: Answer: It's essential to check the grounding connection, ensure proper wiring of the sender and hot wires, and investigate if the gauge itself is functioning correctly.
