Error code 74 on 3520?

[HuskerInVA]

I'm getting an intermittent error code 74 on my 3520. If I shutdown and restart it goes away. Any idea what a 74 is? Code list in manual only goes to 72.

This indicates that the "Display Mode" switch is stuck on. This is the switch above the turn signal. See if there is debris stuck in it. I guess a short or bad switch could also cause this.

Husker:

A couple things, like Roger said, check the switch. If that doesn't do it, check for loose connections, I have been having some problems with my 3520 and in the process of troubleshooting them I have found a couple of plugs that weren't fully locked together (one had come almost completely apart and was giving me an error code relating to the cruise control and MFWD). If all else fails, contact your Dealer, as Deere has been having problems with the clusters and has been replacing them under warranty.

Good Luck,
BILL
