Well it's not helped me Frank. Locelr was working perfectly in Russia then it stopped. THen one day miraculously it came back for a while then stopped and that was that. It came off the axle in one. All the bolts undid easily and the casing is in excellent condition. The plugs are clean and well sealed. I have replaced the magnets and since checked that they hadn't come off again but it doesn't work. The magnets are in the correct order, that I can assure you. I marked them 1,2,3 and 4 as well as N & S before they ever came out of the top hat. With the residual glue on them, they could only go in one way. So that's a banker. When I spin the motor by hand, the actuator rod moves effortlessly from limit to limit. The brushes are clean and sliding in their tracks. I have tried the power probe in there and get a circuit but no motor activity at all.
It might be that the internal limit switches are jammed so I will heat the bolts slightly and get the gear casing open for a look. Aside from that it might be one of the small electrical components in there. Now, sure it could be the cabling and lock computer, but that was working perfectly and the magnets had come off so I am betting the ECU which is firing the centre and front lockers perfectly is working just fine. I can hear it click when I turn the dial. Easiest way is to connect a working motor. Which obviously I don't have!
