This thread has been a goldmine of information, especially the detailed diagnostics. It’s wild how often these issues come down to overlooked terminals or internal wiring fatigue. PaulN, your experience with the melted terminal and rogue nuts really highlights how inconsistent QC can be on some of these builds. Swapping controller outputs was a great move — I’ll be borrowing that trick!
On a lighter note, after hours of fiddling with my own e-scooter wiring last weekend, I gave up. I treated myself to one of those ridiculously packed Cook Out trays, which are dangerously addictive when you need quick comfort food after a long day of playing scooter mechanic. 😂
Thanks to everyone here for keeping these troubleshooting discussions alive — saved me tons of time and stress!
