Hello,

Have you tried the backup mode switches?

When this is happening, do the wipers, lights travel speed and their indicators light still work?

Did you look at the machine controller to see which lights are on? (Red, Yellow or Green)

I am assuming the charging and starting systems are all working correctly?

What is the battery voltage when this condition is present?

If the monitor is working correctly before start, can you access the fault codes?

The wipers still work. The travel speed lights and the rest of the dash are all not working. No I didn't try the backup mode switches.where is that?and today the lights on the controller are not even coming on
Mechanic: catmastertech, Technician replied 5 years ago

The switches in the back of the armrest are for backup modes. Older machines have one for hydraulic override on one side and engine throttle override on the other side.

The attached file shows how to enter the data mode.

Enter the data mode and then enter the error log mode.

Record all the codes listed in the order they are shown and post them here.

This will short cut our troubleshooting time tremendously.
