The bottpm-line question is, would a professional with the right tools need two and a half hours to reach the conclusion that a hub motor does in fact work? Just how long does it take to try every combination of wires?
This is the full entry logs for the work done by the ebike shop (with in-house techs) I used. I wanted them to diagnose my hub motor and see why it wasn't working. Now, where I come from $80 an hour is a lot of money but I'm willing to pay it if the time is well spent. So the question I have is, where you come from (the ebike world), does anything seem unreasonable or unlikely about a circumstance where this amount of time is required for this effort? Is this the typical amount of time it would take any ebike professional tech to accomplish this? Is "2.5 hours" or "two half hours" closer to what you'd expect?
November 15, 2018 - Customer brought in a rear wheel hub motor, battery, controller and throttle, parts from 24V X-treme eMtb, off of bike frame (bought 2 years ago). Throttle is not original or from X-treme, customer thinks battery and throttle are okay. Please diagnose.
November 26, 2018 - Technician MC connected up motor, controller, throttle and 24V surrogate batteries - does not work. Tested motor with Lenz law and tested okay. Li battery is sitting at 28.5V, unable to load test. Negative battery lead on controller is worn, possibly damaged. Throttle wires have been cut and repaired, and have tape around them. Is 3 pin throttle; do not have another 24V 3 pin throttle to test. Tried connecting 3 of 7 pins from another throttle but does not work. Recommend replacing controller and throttle. 2.5+ hrs.
(the rest is parts, 1 controller and 1 throttle.)
Is this reasonable or excessive time?
