Re: [FWDLK] 57/58 PLYM fuel and temp question

[Curtis French <cmf392@xxxxxxxxxxx>]

A lot of the 50s and 60s fuel and temp (or even oil pressure) gauges had a bimetallic coil inside the gauge that was heated by the current running through it from the sending unit for that gauge.  The expansion and contraction of the coil makes the pointer move.  It doesn't move immediately in response to the increased or decreased current coming from the sending unit, but eventually will as the coil warms up or cools off.  Makes for a pretty slow responding gauge.  Not so terrible for a fuel or temperature gauge, but pretty dumb for an oil pressure gauge, which is why my Charger has an aftermarket mechanical oil pressure gauge hung under the dash.

Hello List

I wonder if anyone has had this experience,,,,,,,,

 

I have just noticed that occasionally ,,,after the ignition is turned on ,,or even the accessories,, there may be up to a 5 second delay until the fuel level or temp gagues register.

 

I checked all grounds and the 'ACC' pole of the ignition switch,,,,all is fine.

 

I drove around the neighborhood this beautiful morning,,,,had a ball,,,,,she ran like she was new,,,everything was fine,,,,,, turned her off,,,let her cool down for about 30 minutes,,turned on the ignition,,,,,,about 3 seconds till the gages came to life,,,yet radio and blower were instantly on.

Am I in a time warp?

Has this happened to anyone??

 

Thanks for the help
