Massey 8690 flashing 4wd light

[ricky_rascal]

Pretty much as in title. 8690 dyna-vt without any warning the 4wd light on dash is flashing and isn't going into 4wd. Not my tractor but I drive it. Haven't had time to look through manual yet but could it be something simple like a fuse? Any advice appreciated. Thanks.

Not had this happen before but whenever something weird occurs with mine switching off and leaving it a minute or 2 before starting up often sorts things out.

Had 7480 dyna vt doing this and it was the solenoid had given up. Although I think that put it into constant 4wd. The flashes should give you a code if you count them.

It just flashes constantly and doesn't appear to have a pattern to it. I'll take notice tomorrow just in case. It's not in 4wd.

Steve, yes a switch off and give it a minute solves a lot of issues and it did for this issue the first time it did it. As you'll guess it doesn't now.
