 tc-30 warning light problem

The other day my battery, air, and oil light came on at the same time. It does this when I shift the high-low range lever into gear. When I switch to neutral the lights go out. It starts off dim then gets bright. Checked safety switch, checks ok. Anyone have any idea what would cause this?

Untaped wiring harness starting in back, then went to front by engine. Didn't find anything that looked shorted out. Finely retaped harness, everything seems to work ok now. May have same problem again, sure hope not.

Shorts can be hard to find. Hope you have it solved but if it shows back up and I do not know this tractor what happens is the light comes on and you turn on the tractor lights, does that affect the warning light? You may have a loose ground. Also with it not doing this in neutral but when in range I would look at that switch for issue with connection or back switch.

seemed ok for about an hour. Haven't had a chance today to look at it. But this time the power takeoff light sends it bright. Thanks for the input will check all ground connections tomorrow.

Took loose main battery ground to tractor frame, every things working like it should. Strange it would start tractor ok, but not have enough ground to mess up safety lights.

 tc-30 warning light problem

Thought I had it fixed, can not find anything wrong with wiring harnace. Have double checked all the switches, but the oil, air, and battery warning lights come on dim then get briter. I ohmed the diodes, but by my repair manual I am thinking that they are breaking down. The lights only come on when I shift in to hi, med, and low range. Anyone out there have any suggestions. New wiring harnace is around $750, but I can't find anything wrong with this one.
