Oil temp gauge issue

[David Anderson]

I never followed up with a post on this.  I cleaned all my wiring connections and grounds at the wiring panel below/left of driver and reinstalled.  I also added another ground wire to the gauges.  They are all on a common ground.  I just returned from a 600 mile trip.  It solved my problem.  The oil temp gauge doesn't move when I turn on the lights now. 

It makes sense that there would be much resistance on those cable connections since the wiring is 1985 original.  Polishing them up did the trick.

Why do you need a engine oil temp gauge?  Isn't the water temperature gauge good enough?   I wouldn't mind a temp gauge on my Allison, but don't need one for the engine.
