 Topic: 8030 Idiot lights
Posted: 08 Feb 2025 at 9:34am |
8030 FWA Powershift. When I turn the ignition switch to the "on" position, which dash lights should come on? None of mine light up. When I push the test button, all the lights do come on. Can I assume that the sending units are bad? When running, sometimes the trans oil pressure light will come on intermittently.
The tractor is pretty new to me and starting to go through it and address some issues. Thanks in advance!

The volt lite far left side and the engine & trans pressure lites. I found the white wire harness that plugs into that assemble on the back side of it can cause trouble. Dave

A factory service manual is your best bet. It tells exactly how the warning lights work and how to test them If you are not familiar with the tractor id get a operators manual too

Do you mean the harness that plugs into the back of the lights?

Already have both factory manuals. Tractor is at my mechanic's shop. I will get him to check the wiring harness out.
