good job...
yes sometimes its the simple things that get ya ;o)

Fixed it!
Found a loose cable at the controller.
I find it amazing that you can get so many codes from a loose wire...LOL
Thanks for your help :)

The serial # of the truck is:
F807N01532B

The battery is new and charged with no bad cell's.
Checked all of the wiring under the battery, motors and control panel.
The truck is dry also.
I will post a serial number when I get to work in a few hours.

There is one thing here that is strange and that is that the battery indicator on the dash never goes to full, it is a few bars down from full. When the key is turned on all bars on the dash come on, so I know they are not burned out.
The battery voltage is set correctly.

By the way, this truck has a AC2 Zapi controller for the drive and pump. Pump motor is DC as it has brushes.

first things first
serial number please?
secondly, is the battery charged fully? what state (condition) is the battery in? make sure its charged fully and all cells are in good condition.

Run a load test and check each cell and make sure you donot have any failing cells. Faulty cells can cause low voltage under a load and can cause random codes being triggered.

Check the cable tray where the cables go under the battery to the rear of the truck to the control panel. Any corrosion? Cables eaten up from acid corrosion?
Too many codes showing up

has this truck gotten wet (from rain or some other source such as pressure washing?)
