My Dad has a John Deere 425 that he got 20 years ago or so. It's reasonably well maintained, but recently got a an issue where it just won't start. Stranger yet, the dash panel won't light either (With the operator in the seat and the key in the usual position where the dash lights up). The LED's on the chip that has the fuses won't light either when the key is turned.
We did a continuity test on the fuses and they're ok. The battery voltage is also 12.6, so... reasonable. The contacts are clean and were just doused with contact cleaner after being wire brushed. And the entire thing was blown out by air compressor just to make sure before cleaning.
Not sure where to go from here. Any advice would be great!
Thank you so much!
