Title: 460 No oil pressure or water temp gauges
Post by: twistedmac247 on August 25, 2014, 06:22:29 PM

New thermostat and oil pressure sensor. But my gauges aren't reading could someone tell me how to wire them up properly? There in only one screw on the top of both sensors

From what I know and remember wiring up gauges...positive negative and signal. The one wire on the sensor is gonna be your signal. Make sure you have juice going to your gauges then you need your signal from the sensor to the gauges.

Common problem on boats is a good ground. Check your grounds on your gauges first then power source

Yeah the guy that had the boat before me had some pretty janky stuff going on with the electrical I'm having a feeling I'm gonna have to end up reworking all the wiring in the boat.. Even tho I don't that that's a bad idea.. But I'll check into that first hopefully that's it. thanks!

You could have the wrong senders. Also, don't Teflon the threads on the sender, it won't allow it to ground. What gauges do you have?

Your gauge wires are hot and ground and you have one wire to the senders... You might just have a broken sender wire... Unhook it from the gauge and the sender put power to one end of the wire and use a test light at the other end if you have power good wire if you don't run a new wire !!!
