Throttle Power Not Working

Just bought new Ecotric 26” Fat Tire a month ago. While riding today, the throttle power stopped working. PAS works fine. Checked connections, no visible issues. Throttle then worked while lifting back tire, got on and nothing. Got home, thoroughly checked all wires. Throttle won’t work at all, even lifting back tire.

Bad throttle or bad connector. Worst case, intermittent controller. Own a voltmeter?

If you can show it's a bad throttle, then you can try to get a new one from Ecotric.
