I opened mine yesterday and found mud and water ingress
, one of the outer cables exiting the housing is short and not giving a very water tight entry/exit, tried a fix by packing some Shimano grease around the cable entry on the inside and once put together again used some sealant externally around the wire exit.
Today I rode 52 odd miles and the pas gave up totally
after about 12 miles and the throttle worked ok then decided not to
and then finally after riding 10 miles with no power the throttle worked again
. The main issue is the pas and believe it must be a sensor pick up or magnet issue with in the motor somewhere in the main body that houses the windings.
Debris removed from inside housing
.
Debris ingress on inside adj to wireing entry/exit.
Light corrosion showing on opposing hosing cover
.
Total mileage approx 260 or about 7 rides worth just under £1 a mile.
Now I've opened it warranty is most likely void so next will be to remove circlip and remove the motor but will speak to Tony 1st. Otherwise if no luck will scrap it and plump for a 36v Q128c 201 with a 22a controller and run it at 10s and also at 12s which should give about 250/260rpm.
