Look whats back. Jayden's jeep visit #2

It has not been long since Jaydens Sarge Jeep has been in my garage. The 4 wheel drive conversion worked great except for a few flaws.
- The hot glue spacers did not work
- No forward/reverse
- Steering seemed to be dysfunctional

Time to fix the first issue; No forward/reverse. Instead of the regular on/off switch type pedal I will be installing a pulse width modulator (motor controller) and potentiometer pedal. I will also be running it at 36v and wiring the motors in series/parallel so that each motor is over-volted to 18v


 Here is the potentiometer pedal that will replace the stock on/off pedal


 Here is the 36v PWM
 
I have laid out the 3 batteries with the controller and charger
I plan to build a camo canvas canopy to cover the rear batteries.
 
I will be running 14 gage wire from each motor up to a connection bar under the hood that will then be wired to the 36v controller in two parallel 36v sets (Right and left). I will be using 12 gage for each motor set and 8 gage for the power cables. For the forward / reverse switch I will be using 4 automotive relays. 2 for forward and two for reverse. They will be placed after the PWM so they should not short like in the original version.
 
That's all for day #1 of visit #2 for Jaydens 4x4 power wheels Sarge Jeep.
