Fully Charge your battery and note the battery voltage
Check for loose, broken wiring.
2 Raise rear of cart and attach a volt meter between the regulator's red and black wires. (Or across the battery)
3 Start engine and run at mid speed, making note of the meter reading.
4 Reading should be between 14 to 16 volts.
5 If reading is above specs, check for a grounded green wire from the starter/gen.
6 If no rise in voltage, disconnect green wire from starter/generator ** and temporarily ground to frame. (It is important that you actually remove this wire from the generator. Shorting it when it is still connected may cause damage to the generator.
7 If voltage rises within specs, replace voltage regulator.
8 If the voltage does not rise then the generator is defective and the first step would be to check the brushes.
** It is important to place a thin wrench under the wire to prevent the stud turning and ripping the wire off the stud inside the generator

With volt meter measuring across the battery, with no pedal I get 13V
Cart on jacks in gear, Push pedal it drops to 12.6v and holds there no matter what the engine speed is
Located green wire and unhooked
Now my question is, do I run the green wire to ground or run a ground to the stud on the starter?
