electrical issues on older Kubota

[HakonJ]

Hi

I have an older Kubota (M5950DT) with some electrical issues. The rear lights on the left side of the tractor don't work at all. If I turn on the indicator to the left, a fuse for the indicator lights blows immediately. Blinking to the right works all fine, as does all the rear lights on the right side. Another fuse blows if I turn on the warning lights. The parking light, which share light "housing" (sorry for my poor vocabulary) with the indicator light, works fine on the front left side.

Is there a short curcuit related to the indicator lights? Could the problem with the fuses blowing be related to the rear lights not working on the left side?

How should I proceed to troubleshoot and fix this problem?

My guess would be that there is a short to ground (tractor frame) somewhere in the wire going to the left indicator light.

Thank you for your reply. It seems likely that there is a short in the wire you refer to. What I don't understand is why this would cause the brake and driving light not to work at all on the left hand side (unless this is a separate issue). Any clues? Are there any known problem areas when it comes to shorts in these types of wires?
