I think that you will find that the clutch circuitry is all same, same for all R22's.
You can bypass the problem usually. if it is not just a blown fuse as ivor points out.
You should have in your kit a short piece of wire to short circuit the malfunction when next you recognize it, so as you don't cop a large bill from ol' mate engineer who has to drive way out to where you are, on a sunday arvo, and do exactly what you can do with your bit of wire, until he gets it back in his hangar on a sober monday!
Get some friendly advice as to how to engage the clutch with the wire, and you need not worry about being left out bush.
Get good advice, because if the actuator motor is smoking it would not be a good idea to then smoke the rest of your electrics.
