[DeTomaso] Temp Gauge Rise

[JDeRyke at aol.com]

Yes- check ALL the grounds and if you have one, use a GOOD VOM to check 
your cooling system which should show less than 70 millivolts output betwewen 
the water and ground. The check will not work with a cheap VOM. This will 
help localize the grounding problem to a single circuit. It may be that your 
oil pressure "changes" when you turn on the headlights too.... Good luck- J
