Help troubleshooting Zapino - No power to wheel

[gge5]

Hi all. I'm trying to troubleshoot a friend's 2007 Zapino scooter. He recently purchased it from a previous owner. They claim it was dropped on the right side while the power was off, and now power won't go to the wheel.

The error LED in the instrument panels flashes 1 and 2 repeatedly. - -- - -- - --.

From the user manual:
First flash 1 time and after a pause then 2 times again
problem with connection of throttle, broken wire is loosened

We thought that the throttle might have been damaged from the fall, but I checked it with a multimeter. The throttle is sending a signal (0.8V - 3.0V). The headlights and tail lights all come on. The battery sits at 64.5V, and this is a 60V SLA scooter.

He says that, at one point, the wheel spun up when it was powered on, but the speed was uncontrollable. It truly seems like a stuck throttle, but my multimeter test disproves that...

I'm thinking of checking continuity of the throttle cable to the controller. If that checks out, should I open the controller to look for damage? Has anyone opened a Zapino controller?

Any other ideas on how to troubleshoot this?

You are on the right track. Perhaps 90% of problems with an ebike or scooter are bad connections at a connector. Look for contacts backed out of the housing in particular. After that, look for broken wires, cut wires, etc. A wire can be pulled apart with the insulation looking ok. So continuity checks can narrow down the area to search.
