Hi d8veh, The test I have just done sounds similar to yours, and was suggested by Neptune following testing with a multimeter, and then with a "brushless motor tester". He also suggested a final test connecting one lead of the test lamp to the motor casing, and the other to each phase wire in...

GT85 is a bicycle maintainance spray, "lubricator, pernetrator, and water displacer with added PTFE" according to the tin!

Update. Rigged up a test lamp, got a glow from A-B B-C A-C. Difficult to connect to hub shell whilst spinning it , but holding a bare wire on to it, or on to the axle brought no light! Motor is now stripped again, and sitting on a radiator, will leave it there for a few days. Any...

Hi Shemozzle, Good idea, I will separate the motor again, undo the Phase wires and test continuity as you suggest, whilst the motor is "drying out". I have a feeling that all will be well with the wiring, as there in no external damage and apparantly all was working fine until it was...

Hi Shemozzle, I have managed to borrow a small 3 leg gear puller which should do the job. First time I did it, put two wheel nuts on the axle and banged it down hard onto a block of wood whilst holding the sides of the rotor. I still have the bruises from when my hand slipped! Eventually, when...

Just replied to your earlier post! I will read your post on alternators, but I have a gut feeling that water/damp is still at the root of this. There was a considerable amount of rust on the stator and rotor magnets and the central shaft, so what the water has done to the joints is anyones...

Thanks Dave, as you and Neptune have suggested this is something I will try over the next few days

Neptune, thanks again for the advice. I will take the motor out again and leave it to dry out with gentle heat over a few days. The marking on the multimeter is 2m, so I presume this is Megohm. I will do the test lamp, takes me back to messing about with cars in the days before ECUs and...

Tried this today. Set the multimeter to 2k (lowest setting). Connecting probes together gave zero. A-B, B-C, C-A all gave reading of 0.001. Highest setting is 2m. Touching probes together again came to zero. Each phase wire read 1.0 when "earthed" to the motor shell (its back in the wheel)...

Thanks again, I thought it was strange that I was getting no reaction at all from the tester. the knowledge on here is fantastic. Will keep you updated tomorrow!

Sorry for the crap typing! should read OK and Neptune!

Thanks Dave, I hope so too! Following another thread on here on replacing sensors, I got some SS41s as replacements from Conrad Electronics. If all else checks out OKJ as per D8veh and Nepyunes suggestions, I will have a go a replacing them!

Thanks Neptune, I will try this tomorrow, and put the results up on here. The motor was badly waterlogged when powered up again, but I did think the windings would have survived. IF this proves to be the case, I will have a go at the Hall sensors!

Thanks d8veh, No I didn't know that. I was following the instructions that came with it, which say "turn the motor clockwise, along the normal advance direction" for both "winding of the motor" and "Hall of the Motor" tests. May well be an incorrect insruction, I will try this in reverse...

Hi Shemozzle, Some days are better than others! Got the stator plate out with liberal amounts of penetrating fluid, and cleaned out all the rust. As luck would have it I had ordered a brushless motor/controller tester from China, arrived this morning. So I reassembled everything, took some...

Well Shemozzle, you were right, the cover is pressed on, and I managed to remove it by placing the plate over a 4" underground soil pipe connecter,( a perfect fit and very strong) and tapping firmly. The water damage is worse than I thought. The end of the bearing the plate pushes on to has a...

Thanks Shemozzle, I really appreciate the offer. I am hoping that the problem is water damage (eg the Hall sensors have blown due to being wet when powered up), as apparantly the bike was working fine until the death of its owner. The front wheel was exposed to three months of summer rain, so...

Yes, SWXB of course, rubbish typing! I was thinking of trying that sort of approach, but dont want to do any damage! The wires come through the axle on this side, so will only have the one nut to work with (without disconnecting all 8 wires in the connector). I got the motor separated by a...

Thanks Wurly, No it only operates in sensor mode unfortunately. I have read that water is one of the enemies of the sensors?

Hi all, My first post on here is a plea for help! I have recently caught the ebike "bug" after buying a Raleigh Dover panasonic crank drive bike for my wife and trying it myself. Fantastic machine! I bought myself a much used and filthy dirty Torq 2 a couple of months ago (spent all the money...
