I still think you have either burned up your TOD engagement solenoid or the clutches themselves. Just my two cents... I would do as I said and test your solenoid resistance... and if that checks out ok, double check that all plugs are clean, dry, and plugged in and if that fails... pull the TOD and tear it down. Just what I would do... then again, this is coming from a person who keeps tearing things out of his VX! lol

Good Luck!
