16 voltage high verify voltage \>86vdc, if higher,  
run lights to reduce.

This happens just after the charger shuts off and the surface charge has not bled of the batteries. This is a normal situation and no fix is required.

The cart should run when the code goes away. Should only take a few minutes to bleed off the excess charge.

Did you find a solution? Mine is doing the same thing you are describing. It happened after I pressure washed it. I tried the headlight suggestion and no luck

Any batteries will work.  
A shop will generally only work with “approved” parts.

The shop suggests that new batteries will fix the high voltage code?  
I’ve been wrong before. Will they guarantee it will clear the code? It sounds like they are parts seller/swappers.  
Measure the voltage at P1 on controller. About 86v triggers the code.

If voltage is ok, controller is bad. IMO  
Take a battery out of the string to see if you get a low voltage error. Won’t fix anything, I’m just curious.
