3.3 Installation Check List 

Before operating the vehicle, complete the following checkout procedure. Use buzzer code 

as a reference as listed in Table 1. 

 

Caution: 

  Put  the  vehicle  up  on  blocks  to  get  the  drive  wheels  off  the  ground  before  beginning  these 

tests.   

  Do not allow anyone to stand directly in front of or behind the vehicle during the checkout.   

  Make sure the PWR switch and the brake is off 

  Use well-insulated tools.

 

 

• 

Make sure the wire is connected correctly 

• 

Turn the PWR switch on.   

• 

The fault code will be detected automatically at restart. 

• 

With the brake switch open, select a direction and operate the throttle. The motor should 

spin in the selected direction. Verify wiring or voltage and the fuse if it does not. The motor 

should run faster with increasing throttle. If not, refer to the Table 1 code, and correct the 

fault as determined by the fault code. 

• 

Take the vehicle off the blocks and drive it in a clear area. It should have smooth 

acceleration and good power.
