Elect Water Temp Gauge Installation Problems???

I have a Sunpro electric water temp gauge I am trying to install. It has three posts on the back. Positive, Ground and Sending unit. Pretty simple hookup, one wire for each. But when I turn on the key, the meter pegs out at the max 280 degrees. The car has not even been started and is cool. Any ideas, or could I have a bad gauge?

Re: Elect Water Temp Gauge Installation Problems???

not positive on that particular guage, but with most, a reaction like that means the wire to the sender is open (not connected) it could be backwards with a temp guage tho.

Try this: pull the wire off the sender, stick a peice of wire or a paper clip in it, and ground it. Turn on the keysee what the guage does, take it off ground and see what the guage does. If you can make it move this way your wiring is good and the sender is then bad.

What I have done trying to troubleshoot is this. The put the positive to a fuse, ground to a ground. Then with the key on, touch the wire that is hooked to the sending unit to the appropriate terminal on the gauge, and it pegs the gauge at 280.

What kind of sending unit? It has to be for gauges, not a idiot light. As Jim said , what does the gauge do without the sending wire connected to anything, and with the key on?

The sending unit is the one that came with the gauge. I mounted it in intake as instructed by the instructions. If you don't have the sending wire hooked up, the gauge is at zero with the key on. If you touch the sending wire to the post, it pegs to 280 with the key on.

Re: Elect Water Temp Gauge Installation Problems???

then I think your guage AND wiring are fine.

Check resistance from the post on the sender (with the wire disconnected) to ground (alternator case is good) if it is zero, the sender is bad, or incorrect for the guage

Checked the resistance, and the meter does respond with resistance from the sending unit to the alternator case. Now what?

Re: Elect Water Temp Gauge Installation Problems???

What amount of resistance? A high amount, ie, 5K or more, for a colder reading.

Midscale of gauge may be 200 ohms.
Should have less than 1 ohm from sender body to ground, intake, and less than 1 ohm to alt case.
