Hey everyone, having a weird problem with my 2014 E4, cart was running fine for years, today it came off the charger and went to take it for a ride. It moved approximately 4 feet and completely shut down, I cycled the key and it briefly displayed code 51 reference the controller low voltage, all the batteries are holding at or around 13.x volts and the dash reads 99%. Any ideas? Thanks in advance for your help.
Where are you at now? Completely dead?
Key switch possibly? Look for battery volts at contactor coil and controller P1.
It moved approximately 4 feet and completely shut down
Can you expand on this a bit? Does this mean the dash display went totally dark? If not, the cart may have been showing a code as to why it shut down. Cycling the power may have been a good attempt, but it loses the original cause of failure and sometimes replaces it with another. This leads to running down the incorrect path.

-51 Capacitor volts are low before the line contactor closes.
Not simply a low battery/low voltage error. (That would be a code -15)
This is a “Look Ahead” check that makes sure the caps are charged before it commands the contactor to close. If not charged enough, there may an inrush of current that can damage your controller.
Sometimes this is triggered when you flip the MainDisconnectSwON, the KeyON and press the pedal within a short time.
Was this a one time event? or is this a repeatable/consistent error?
When exactly does the error show up? (at KeyON, or when Pedal Press).
I believe the caps get charged off P1 on the 23p Main Harness connector through a small resistor/charge circuit inside the controller. Sometimes this goes bad and needs repair. This might also be simply a loose connection on P1.
Has there been any changes since the car was working properly?
Have you been having a lot of weather/rain?
It shuts of, I can pull the ebrake and recycle the ignition and move it a few feet again until it repets
Yes sir, the dash goes completely dark and the cart beeps.
We had experienced a heavy rain and the car was outside and uncovered.
I am unfortunately out of town until tomorrow when I can get there to mess with it. This is all coming from information while speaking with my wife.
I had her face time me and so she could check battery connections and terminals on the cart to make sure everything was tight.
It is almost functioning as if it is a loose connection that makes it completely lose power
Two very important clues here.
This sounds like a key issue. Either it is on the edge of ON/Off. A super observant driver might even notice a -11 on the dash if it comes back on without fumbling with anything before they roll to a stop.
Do you have a big wad of keys on this ring? Sometimes the swinging action will simply rotate the key towards off.
To test for a sensitive/failing key switch, you need to remove the plastic part of the dash pod behind the key so you can get to the wiring for inspection. (sometimes the little push on connector might be loose).
Then spend a trip (or two) driving around with the key switch jumped.
Just tried to drive golf cart and it went around the block but then shut off and gave error code 88, it started back up and shut off a second time and it said 11 and then 88 again
-
Did you do anything with the key switch?(as suggested above)
-
Was the beep also present when the car shut down(display dark)?
Or have the symptoms now changed? -
When you note the 88 on screen, is there also a tiny little yellow electrical plug on screen also?
The -11 is set because the controller rebooted and detected that the pedal was pressed when it woke up. Lift foot to clear and press pedal again.
I have not had the chance to get down there to mess with it yet. However, it is allegedly back to normal operation now after 24+ of shutting down… I am assuming something got water logged in heavy rain and has since dried out.
Any recommendations on checking on anything there?

You are kidding, right?

No, I mean, ensuring things are seals to prevent issues from happening again.
