Thank you for that. I have got the unit on the bench at the moment and am trying to see if it works with a battery supply. I have 8.5 ohms on the Stator coil and 1.4 ohms on the rotor segments which seem to be ok when you rotate it by hand. Goes on and off of course but when it come to rest it is always about 1.4 ohms. Seems reasonable to me but the rotor resistances may be a bit low. What you think? The set up was - wire to the stator coil - through the coil and then the other side of the coil was connected to the first brush and the other brush connected to a wire coming out and also to the shut off switch in the top. Can't make head nor tail of it at the moment. Cheers Colin All those measurements seem correct to me Colin so I would say the motor is not your problem!

I have got it running on the bench so at least I know that the motor is ok. Test run for 2 hours and warm but not hot. So happy with that. All I have to do now is work out the switch and what it does. Not sure about the quality of connectivity in the switch contacts so it is apart at the moment. Not too worried now it all now as at least I can connect another temporary switch and run the motor if this switch proves to be unrepairable and then I can use the car if it rains. Does anyone sell the switch ? Cheers Colin

Hello, Thank you for the advice. I found out that the contacts were not making very well in the switch so soldered a bit of solder on the bases and scraped them smooth and flat. I also drilled two small hole in the ends of the switch so I could push the contact shuttle across and back with a small screwdriver to prove it was going all the way. Also useful for some switch lubricant when I get some. Worked ok and now the switch is positive in action and continuity. I put the motor back in the car as needed to get about. The motor is only working one way at the moments as haven't worked out how the switch changes the polarity of two wires. But at least I can see where I am driving. Lucky really, as the next day my son's BWM threw it's diff and I had to go and tow him home and to the garage the next day. Rescued by a 44 year old car !! I will report in when I have finished the window wiper job. Cheers Colin

Colin, I hope you will be posting some photos of the P5B towing the BMW.

Well, slightly of track here, but I have been considering the action of the wipers. I, and it seems some others on here are not too keen on the parking feature. I have added another switch in place of the wiper rheostat that is the right shape and when operated (on - release - off) runs the wiper while you hold down the switch. I find it very useful if there is a bit of drizzle on the screen. It also saves a lot of use on the original switch. Anyway, I saw this Rover for sale and it's quite an old one but been converted to V8. I notice that the wiper arms have a "kick" in them, I assume so that they sit at the bottom of the screen, which would suit me. Did the early ones have a "kick" in them. Does anyone have a D reg Rover 3 lt to see? Cheers Colin

All P5's and P5B's had the same off screen parking arrangement carried over from P4's and had the same wiper arms - early saloons had shorter wiper blades

Cos I quite like it like that in the picture. I think that the Arms are stainless so they would flex into shape I suppose.

May have been adapted - its difficult to see but could be off another car entirely.

I have a D reg 3 litre and the arms have a bend just before the blade is attached. Is this what you mean by a 'kick'?
