Hello experts!
I've had BBSHD installed on Specialized Fuse 6fattie just over 2 years and it has been perfectly reliable, it hasn't failed at all even when i sometimes abuse it hardly.
It started some intermittent power cutting randomly couple weeks ago, after i washed the bike with hose (yes, stupid, i know), of course the battery was not installed.
There was a little water in power cable and after drying, worked again perfectly like 300 kilometers.
Couple days ago it started to work weirdly again.
First gearsensor started to work intermittently, i disconnected that and after couple kilometers PAS stopped working in 1 and 3, worked like step 1 when in 5. Throttle worked flawless all time.
I disconnected the battery and waited like 15mins, after that PAS worked again, until after like 10 kilometers it suddenly put 100% power with any PAS level. Again reboot, and worked rest of my ~25 kilometer trip.
After couple hours stand, bike worked again perfectly about 20km trip to my friend, we had couple hours fun evening and when i started to go home, bike worked badly like 150 meters giving intermittent power all time and died. I stopped and disconnected everything, leaving just Eggrider and throttle, motor still not running.
It started to "jerk" like 1/10 rotate of chainring every time i turned Eggrider on and no power to motor.
When i got home I tried DCP14 display and it did show Error 12H, after that whole system cuts off when i push throttle/pedal and battery shows red/green leds, it just "jerks" that small movement to chainring and dies. I can turn whole system on, but it dies instantly when pushing throttle/pedal.
Bike is also very, very jerky to push backwards, about 3-4 times harder than normally with BBSHD. Forward pedaling works normally.
That jerky resistance when pushing backwards is weird, there is no power/battery in bike so broken controller should not be involved to that.
Battery is ok, it works in my brothers BBSHD setup, but i think my motor/controller is broken..
And update:
This is going more mysterious.
I did disassemble whole system from bike to get it to table for closer inspection.
Every wire and connector seems perfect, no bents, burns, broken insulate, nothing.
I did tear down for motor and rotor, stator, every electronics, windings etc. looks like brand new, also nylon gear looks like it's not even used., no signs of water or rust anywhere.
System turns on, but still no life in motor, i tried also with brand new controller, 2 displays (eggrider v2 and DCP14), and with 2 throttles, mixing them together, still nothing.
New controller shows an error "30H No signal", old controller doesn't show any errors, both shows battery voltage right.
Now it doesn't die when throttle is pushed, it just don't do absolutely nothing, not even chainring "jerk", also no more red/green over current leds in batterypack.
I have no idea what is going on, i think i'll order new main harness, just to eliminate that fail option. If that doesn't help, i don't know what to do.
Any ideas?
