Hello all, new guy here. Trying to help my cousin with a problem. He purchased a 26" Fat Tire a number of months ago, its still under warranty but there are no service centers or locations anywhere near up that will touch most ebikes, let alone do warranty work on a specific brand, so we're trying to resolve this with ECotric's tech support and while they're nice enough and seem happy to help, we're getting nowhere. This started about a month or so ago, one trip to the next, his bike wouldn't move under power, pedal power only. Checked the battery, its charged and the display powers on and shows data like battery life and mileage (517 miles if that's relevant). Ecotric diagnosed a bad controller unit and sent him a new one, I did not assist with this, so I can't say for sure what was done. Didn't resolve the problem, so they said maybe a bad motor. He brought it to me and I swapped out the motor last night, still no electric movement.
I'd like to start from scratch and first see if the symptoms are familiar to anyone, or barring that, if there is a set of diagrams or assembly/disasembly instructions online somewhere so I can start troubleshooting components. I see the cable that feeds the motor for example, has a bunch of pins (yes, I lined the arrows up on the connectors when I reassembled it), but which pin does what and can I troubleshoot it with a multimeter? What about the throttle controller? Seems like a spring return twister with a simple cable, maybe its just come undone, but the way everything is covered and sealed up its hard to trace where the various cables go to and from.
Anyone have any thoughts? Troubleshooting flowcharts? Wiring diagrams? Some chicken bones and a voodoo doll?
Thanks!
