In the never ending saga to get my Blackcomb bike build with the Tmotor U-15 running properly, I put a Tronic 250r on it. Ran great for about 75 miles (FOC), no top end cutouts as with the Flipsky 75200, just a faint low-mid range shudder that I was trying to tune out.
Yesterday, ADC1 throttle pegged at wide open- fortunately while I was stopped with rear wheel lifted off the road. Seconds before i heard a sort of light metallic clinking, so stopped to investigate.
This is of course the most dangerous condition possible on an ebike (2nd being a battery fire). This controller has on off switch capability, and the button i installed next to throttle worked and shut it off.
In subsequent bench testing, the unit still turns on and off normally- blue, then blue+green led. Throttle functions ok until 1/2 open, then pegs at WOT and stays there- the separate ADC2 regen thumb throttle is still working normally and will kill it, or shut off switch must be used.
Again this was a sudden malfunction- was working normally. 15s battery pack, all parameters set within Tronic specs, ADC1 and 2 set to 3.29v max, all wiring and connections triple checked, Comm port JST plug tight, swapped on a brand new throttle- no change, zero smoke/heat/smells/burned components or obvious issues, further noises or other malfunctions.
Seems to me a board component failure. Opinions?
