Stacyc 16 - Powers on, green LED, but nothing after

Premix4Life

As title reads:  Its a 16" Stacyc. Powers on fine and single beep occurs.   Green LED remains on.  Twisting the throttle does nothing.  I've replaced the throttle assembly with a new unit to no avail.  Same behavior with replacement installed. 

I'm on a few Stacyc FB groups but no one has experienced this specific problem...   Probably going to have to purchase an entire motor assembly but wanted to see anyone here has crossed this bridge.  Thanks in advance moto bros.

Ours has done this before and it was a blown fuse. Hopefully that's the issue for you.

Thought the brushless were also fuse-less.   I will def double check this, now, when I get home this evening.  Thank you for your comment.

Brushless ones also have a fuse. It's a 40A blade - get a pack from the auto parts store.

That's the high output brushless motor - no fuse on those. If it was me I'd get out the multimeter and start testing voltages with a battery installed or continuity on each wire. Check solder connections.

There's a chance that stator burnt up too; check resistance of each of the three phase combinations (1-2, 1-3, 2-3). If not balanced it's likely the windings burnt up. If balanced that still may not indicate a good stator, but without special testing equipment you'd never be able to test at home. Good luck

Thank you kindly, again, for the suggestions.  Ride on Brother
