4020 gen and oil light on dim when tractor is off

Posted by dweitzel on May 08, 2013 at 19:42:53 from (208.102.68.119):

The gen light and the oil pressure light will stay on very dim after the tractor is turned off. It seems that this is intermittent and sometimes the lights are on, other times they are off. If they are on dim, BOTH lights are always on?

I believe the gen and oil light are both on the left battery circuit, but one is on the light switch and one is from the key switch? Any ideas where to start trouble shooting these?

If I disconnect the positive from the RIGHT battery, both will go off. If I leave the right battery connected, the right battery will be discharged after a couple of days.

Sometimes the light switch will light a couple of lights, but most times it does not work any lights.


Any ideas how to start trouble shooting this problem?

Thanks.
