Please replace the controller If the voltage of the accelerator changes normally .
D. Quick determine controller failure.
Pull out the plug of the accelerator. If the controller still reports a fault after power on. Then
there is fault controller
Controller fault light is always on. No walking. Then need to check below step one by one:
1. Measure whether there is voltage output 0-5V from the accelerator (Between J1-1 and
Negative pole)
2. Short-circuit the J1-6 on the 14-pin plug of the controller with the 7th line on the 5th pin,
and turn the accelerator after restarting the truck to see if there is walking
3. The brake locked, Remove the brake (keep the brake cable connected) turn the
accelerator after restarting the truck to see if it is normal
4. Remove the brake disc (keep the brake cable connected) Connected The motor M1
and M2 directly to the positive and negative poles of the battery. And observe whether
the motor rotates normally. If not, is the motor failure
5. After all, above test finished and all result are normal, then it should be controller
problem.
Turn the Multimeter to 24V DC, insert the pin into J1-1(Accelerator 0-
5v speed signal)2(Negative). Turn the accelerator after Power-on.
And observe whether the Multimeter reading has a linear change of
0-5v voltage
