Throttle not working properly.i

[JCooper52]

I have a 26" fat tire bike and the throttle only works when the front wheel is turned completely to the right. Has anyone experienced this situation? Not sure what to check in order to get the throttle working properly again.

It sounds like a wiring problem. Turning the front wheel can put pressure on the wiring harness. Some ebikes, particularly with Julet throttle connectors, have had issues with moisture getting into the connector and causing corrosion.

Put the bike on a work stand or just raise the rear wheel off the ground (assuming it's a rear wheel drive). Locate the throttle connector in the wiring harness. Turn on the power and wiggle the connector while twisting the throttle. If it works intermittently, the problem is likely in the connector or adjacent wiring.

Make sure the drive wheel is OFF THE GROUND before trying this!

Be careful lining up the arrows on both sides of the connector prior to plugging them in too. If you don't and just mash them together you're going to end up with some really tiny bent or broken pins and that connector will never work. Don't force it!
