my water temp guage hasn't worked since i got my zed last month.(72) the other day my neighbor pulled the wire from the sensor to inspect it and it looked clean. next day i noticed the guage reading about 1/4, then just a suddenly it quit workin.the p o said he never had a problem with it.now it's intermitently workin and not workin.any suggestions, thankyou very much in advance.p.s. when i had the safety inspection done i tld the mechanic to check the guage. he said he had it workin for a while and that all my guages were a lttle screwy.

SOunds like either the connector is loose (squeeze it gently to make certain it's secure to the sending unit) or the wire is broken (less likely). Other possiblity is the sending unit is bad, but I'd expect it to fail completely, not intermittantly.

If Carls suggestions don't clear it up, remove the sensor, clean the treads on it and the threads it screws into, and you will have probably solved the problem, years ago I had the same chase going on, and it turned out to be corrosion in the threads!

That's a good idea too. If you have to remove the sensor, be very careful, steel threads in the fitting, are threading into an aluminium housing. Easy to ruin one, the other, or both.

A little anti-sieze is a good idea on any threaded device going into aluminum.

Don't use too much anti-sieze though. The sensor needs metal to metal contact for the ground. That is why the corrosion on the threads was causing a problem.

while looking for anti-sieze gook($14) i came across electrical contact cleaner($5). thought i'd try the cleaner first,disconected the wire and sprayed both contacts. fired up the zed and temp guage is working. keeping fingers crossed hopeing it's a permanent fix. glad i tried plan b first, cheaper and easier. thanks guys
