I have inherited an old 48v eBike that has seen better days.... and is not currently running.
1. battery was replaced not long ago, voltage test fine, so that's probably fine.
2. original display-throttle was crashed on several times and was highly suspect, so I've tossed that and bought an inexpensive twist grip throttle
3. I don't need PAS, fancy display or brake interlocks.... just twist-grip 4-wire throttle
4. I've wired up the new throttle, but bike is still not working.
Q: how can I tell what *should* be measured coming from the controller output (with *some* throttle) to make sure the controller is ok ?
I am attaching picture of controller/motor connector; 3-phase wires and 6 contacts around the outside
Q: I do have a variable voltage/current power supply.... can I jumper to hub motor connector to make sure hub motor is ok?
Q: if the hub motor is bad, can I keep the existing wheel, and buy 'just the guts' of the hub motor to keep repair cost down?
