Attempting to help my brother with his 2007 Grizzly 700.
He's rebuilt the servo with new motor, and purchased all new relays for the bike.
Tested the switch, its good.
We can manually set the bike to 2wd and time the servo, install it on the bike. Using the switch, it will engage 4wd. After that, it will not respond. Cannot set back to 2wd, unless we do it manually.
Metering the motor plug at the diff, I've got weirdness on 2 pins, that read 9.8 volts and do not switch with the switch. 1 completely hot 12v and 1 switched 12v (with the 4wd switch). A couple of grounds on the other end of the plug.
Anyone have a pin-out or some such, so I can figure out which wires are frayed or broken?
