Started up the GT after 3 weeks sitting and the oil pressure and tach are dead. Any thoughts on cause?

:confused
 
 
Let the car run and charge up battery. Then turn off and restart and they may come back. If not welcome to the guage failure club!
 
make sure your battery is putting out over 13 volts,, aroud 13.2 minimun..

I don't think any FGT battery will put out 14 volts, but the if the car is running the alternator may do that. A 6 cell lead/acid batteries will be about 12.7 to 12.8 volts tops, but the car should run between 13.3 to 14.5v.

If you just charged the battery it can have a higher voltage for a brief time. Just put a small load on it and test again. e.g. hit the brakes for a second to get rid of the excess charge.
 
Yup, they are wonderful guages alrighty.

Be careful what you ask for. He COULD make an error with the decimal, too, ya know! And if I were him - I WOULD!

If I had $100 for every mile you drove I still would be poor! I guess I would have to say you are one hell of a environmentalist, I don't know anyone that puts out less green house gasses from the autos tailpipes than you.

Can say that much for his "HUMAN" tailpipe. Lots of gases come out of there on a daily basis. He has polluted this forum with 12,023 of them as of this very moment! :)
 
ROFL!!!!!!!


"Green" Pockets! :rofl from Washington! :rofl


.....and Shelby you beat me to the punch!

Well good news ! I recharged the battery, cleaned the terminals (they looked clean to start with), reassembled the + & - post terminals, restarted the car and all the gauges work fine now. I am so thankful for the suggestions from you guys - terrific to have such great help!
Thanks again!!! Jim
 
Keep an eye on the battery or consider putting in a diehard.
 
Also, consider sanding contact point of ground terminal to frame; its threaded and dialectric grease is ok too
