Hi All,
Some of you may have read my previous thread about repairing my A2B Metro that I bought as a spares and repair job. Initially I have disassembled the battery with a view of rebuilding the pack. I I think I have a pretty idea on how to do that, but in pushing the Metro round the garage I've discovered that the hub motor is providing a lot of resistance when you try and push the bike or just spin the back wheel.
As a test I hooked up the charger to provide 36 volts to the battery with the battery hooked into the bike (hope this wasn't a bad idea!) with the bike on the stand back wheel up. I gently opened the throttle and the rear wheel span for a moment and then stopped.
At this point I'm thinking that the best idea is to open up the hub motor (as per youtube videos) and take a look inside and see if anything has seized or there are any wires shorting out. While I'm at it I think that I will try and replace the original controller in the wheel with another one on the frame someshere, as I've read that a lot of V1 metros suffer from overheating controllers.
Before I go any further I thought that it would be a good idea to see if I could hook up the hub motor to a 36v supply and do a bench test. The connections coming off the motor are two big power supply wires and four smaller wires which are in a squashed square formation in the plug pins going to the motor.
Any help on identifying what each of the pins are and how to hook everything up for a bench test would be greatly appreciated. I have access to a 36v PSU.
I've had a surf round on the site but can't see this specific information apologies if I've missed it.
Thx
