It'* possible you are getting a partial ground.

Pull the wires off the gauge and ohm them like Bill suggested. Or park it and realize you finally blew it up.

If I blow it up, I'll know, cause I'll do it right.......the first time.

OK so I checked the resistances and following the AutoMeter tech'* guide over the phone determined that it is the gauges black box that is faulty.

The bad news is that this gauge is obsolete. I bought it in Dec/06, ran it for two months and now it'* obsolete.
Autometer tells me that due to low sales volume of this type of gauge, they don't sell them anymore. New temp gauges do not have an intermediate black box that sits under the dash to connect the gauge leads to and the sensor leads to. Ten connections in total.
The new gauge they sell is not the same as the one I have.

Autometer will send me a new black box but have told me that it will not be calibrated to the gauge so may not be accurate. :?

Now I am in waiting mode till the mail arrives.

Good to know it'* not the sensor so I don't have to tear into the engine again.

did they tell you HOW far off the calibration could be? Or is it safe to assume that it will be close, just not precise?

Shouldn't be too bad. You're most interested in the Delta temp between normal and spray anyway.

i assumed that it should be close..

and good point about the delta.

Ya that'* what I think. It might be off a few degrees but I just want to know when to spray. I should know how far off it will be because I know now what to look for in temps and when it'* cold I can compare to ambient temp.

I sure hope they send it by courier and not regular mail. It'll take forever to get here...... :(

December till now and its discontinued
They should send you a complete replacement or a hat and the black box for your troubles?
Too bad allmachtige does'nt work there anymore :P

All is good.

The replacement AutoMeter module arrived today in the mail. That was quick. Much Thanks to AutoMeter. They have great service. No questions asked......well at least not that many.

Looks to be just as accurate as before. As long as it'* within a few degrees, that'* good enough for my purposes.

Great to hear..

Any word on them if this one goes bad, what are your options?
