Combines Duetz Head Temp sender

The one on my V8 is a slip-on. Did you try "squishing" the thing a bit for a better fitIJ

Yes, If nothing is available, I'm going to replace the end, clean the sender, and see what happens. It seems to be a poor design to me.

like Trent, I squeezed my connector down a little so it slides on nice and tight and haven't had any more problems with it.

If you unplugged it and the light went off you have a problem , if you unplugged it and the light stayed on and the alarm finally went off thats ok temp. I would hate to run with one not functioning. The alarm works on a value of ohms not grounding like the other ones. If the suggestions of crimping the tabs a bit diesn't work there are after market outmotive clips that are positive connections. Would take a little research or a trip ro radio shack possibly.
