Has anyone had problems with error code 71 showing up??
I have had 2 spare batteries and after a short while error 71 shows and battery won't connect
Original battery is fine
Any ideas anyone please
Haibike hard seven 4.0 yamaha motor.
Second yamaha 500w battery purchased for longer rides was ok for 2 rides then showed error code 71 and wouldn't connect. Original battery is OK.
Shop where I bought battery exchanged it for another , same again 2 rides later with second battery showing error...
