EZGO 48 volt golf cart troubleshooting

[@FarmCraft101]

Just found your channel because I'm having problems with my cart. Thanks for giving real information that is practical and useful. Thumbs up. I think I have a bad solenoid, and now I know how to test it. I was confused by all the posts having positive voltage. Why do they wire carts that way, where the controller is sending ground rather than sending voltage? I'm just used to control signals sending voltage to make things happen, like how relays are typically controlled in HVAC systems, and other appliances. It seems odd to have the voltage already there and send a ground instead, but there must be a good reason.

[@Golfcartwhisperer]

@@FarmCraft101 did you get it figured out. You can run a wire from the main negative to the small post on sol blue wire. But before you touch it hit the gas then touch and see if solenoid clicks

[@Golfcartwhisperer]

Your guess is good as mine. But I think it’s just dead voltage that really does nothing. But your right most relays and solenoid either have a hot and a ground not both then it changes.

[@FarmCraft101]

@@Golfcartwhisperer I did get it figured out, thanks. It ended up being the reed switch, which I just bypassed. Cheers.

Hey man. Still trying to get my ezgo txt 48v to. run. Switch is good, fr is good, reed sw is good, tow sw is good. Get 14v on white at its, no voltage on black wire at its. Voltage on red at mic sw. voltage on green wire when pedal is pushed at mic sw. SOL does not click. I have voltage going to SOL. 🙇‍♂️🤷‍♂️

[@Golfcartwhisperer]

@@lubywarren have you replaced the its.

[@lubywarren]

Yes

[@lubywarren]

Getting full voltage on black wire with full pedal

[@Golfcartwhisperer]

@@lubywarren I thought you said you are getting no voltage on the black wire that comes back from the it’s.

[@lubywarren]

Yes sorry. 14 v on white wire. None on black wire

[@JTCatfishkid]

I got no voltage at the white wire for the ITS. Also no voltage on green when I press the gas. What is the possible issue? This was following this video step by step

[@Golfcartwhisperer]

@@JTCatfishkid take your floorboard up and look at your pedal box to make see why going on down there. I have a video on taking the pedal box up if you need me to send you a video I will. Do you have any voltage on the black wire for the ITS.

[@JTCatfishkid]

I go no voltage on the white wire and no voltage on the black either

[@JTCatfishkid]

Misspoke in the first question. I got no voltage on white wire. Also got no voltage on black

[@JTCatfishkid]

No voltage on white for ITS. No voltage on black before I push the gas or after. Also no voltage on output post(middle) of controller when I push the gas. Am I right in thinking it’s an issue with the controller?

[@Golfcartwhisperer]

@@JTCatfishkid do you have voltage on the tow switch wires also do you have a reverse buzzer

[@mikeallen3646]

the ITS showed 14v and the return black wire was 14v with pedal not pressed and pressed... BUT on the controller the orange shows 0v when the forward button on but 50v when placed in reverse and the green showed 50v in froward and 0v when placed in reverse Now on the solenoid the yellow shows voltage when key switch on ,the blue showed 0v with and without gas pedal pushed. and both large lugs of the solenode has power constant pedal pressed or not. I by passed the tow switch. I dont know where to go with this.

[@Golfcartwhisperer]

If you have a stock controller, replace it ITS. What kind of controller do you have?

[@mikeallen3646]

@@Golfcartwhisperer just the stock txt 2014 48v controller. that grey wire your talkin about iswhite on mine if that means anything

[@mikeallen3646]

@@Golfcartwhisperer i changed the ITS and the micro switch but still didnt do anything. still 14v showing both side of the ITS . now on the solenoid the blue wire showed 0v. so i jumped the blue wire lug to battery ground and the solenoid finally made the clicking noise but the cart still did not move

[@Golfcartwhisperer]

@ replace the its the solenoid will not click if the correct voltage is not coming back from the edge ITS. Because it senses that the throttle is down and shuts down for safety.

[@mikeallen3646]

@@Golfcartwhisperer i did repalce the its.... so what do i do if the correct voltage is not coming back from the edge its

[@SandraPerez-vu1wc]

Hey Golf Cart whisper how’s it going a while back you told me to see if my key switch was bad. I could jump a wire from the small post in the solenoid to the positive in the battery to see if it would run the Golf Cart runs but it runs without pushing the pedal once I jump the post it just moved any idea why that would be ?

[@Golfcartwhisperer]

@@SandraPerez-vu1wc what type of cart did you have

[@Golfcartwhisperer]

@@TJSmith-h4s what’s wrong is the capacitors inside the controller are bleeding down so they’re are pulling voltage across the resistor to keep charged.

@@Golfcartwhisperer thank you for the quick response. I’ll let you know how it goes

Real quick, is there something that could have killed the controller I need to look for? Don’t want to throw a new one in it and have it smoke? Thank you for your help!

[@JTCatfishkid]

I got 2.73 volts on the black ITS wide when I push the gas pedal to the floor. Does that mean the ITS is the issue since it ain’t 2.9 volts?

[@Golfcartwhisperer]

That’s right. Hit the gas and give a ground to the blue wire on solenoid from the main negative. It don’t touch to the blue wire post until you hit the gas. Let em know what happens. And yes the its is good

[@Golfcartwhisperer]

Make sure the green wire on pin number eight while you have it in Forward has positive battery voltage with the key on in forward But yes, as long as pin 9, 8, and pin 6 have positive battery voltageand the its is reading right t replace controller

[@JTCatfishkid]

Red to main positive. Black to blue wire after I press the pedal. I got 3.3 volts. Just a note. With key off, red to main positive, black to blue wire I have full voltage. Turn key on and have 3.3 volts

[@JTCatfishkid]

Ground from main negative to blue wire makes solenoid click

[@JTCatfishkid]

@@Golfcartwhisperer yep. Got voltage to all 3. No voltage on output for controller

[@Tydog96]

What actually happens if it gets towed while tow switch isn't thrown appropriately? Also, can you expand on testing the middle post on the controller (m-?). Your meter had red lead on main positive, and then using black lead to M-, right? What voltage numbers are you looking for with pedal pressing? Solenoid clicks good as blue wire is grounding as expected and both large posts show main battery voltage (50v+). Thanks.

[@Golfcartwhisperer]

@@Tydog96 if you tow the car in run. depends how far you towed it and how fast. If it was towed a long ways. Then it tears the inside of the motor up.

[@Golfcartwhisperer]

If your M negative shows battery voltage when you hit the gas with the red lead B+ on the controller and the black lead on M negative on the controller check your motor. If you don’t have voltage, let me know.

[@Tydog96]

@@Golfcartwhisperer I do not see a voltage increase when peddle press with RedTestLead on PosBatteryTerminal and NegTesterProbe on the Middle Controller post (M-, goes to A1 on Motor). )Your video test at 13.25). It shows .576v prior to peddle push. Full peddle push results in about .000 voltage result. I unhooked motor (Shunt, not series) and tested with A1 jumped to F1 and A2 Jumped to F2. Connected 12v to jumped terminals and motor seemed to run fine. If I understand it correctly, the A2 motor terminal is always full battery voltage, then A1 accepts variable current from the controller post M- (middle terminal). Subsequently, Forward and Reverse is enabled via 12-13 volts going to F1 or F2. There is no reverse buzzer, but do not know history of cart.

[@Golfcartwhisperer]

@@Tydog96 does your solenoid click in and hold in while you have your foot on the gas or does it click in and out real fast while you hold your foot on gas pedal. Key on in forward.

[@Golfcartwhisperer]

When you hit the gas voltage should go from 0 volts to 48 volts at full pedal. If it doesn’t then replace controller. How far did you tow the cart.

[@JakeStoverOG]

I just checked everything in this video on my 48V ezgo, and I don’t have a solenoid click. ITS checked out fine (got up to 2.9 steadily), solenoid has voltage on all posts, and key switch & run/tow switch seem to function fine. I’ve already replaced solenoid, what else could it be? Thanks!

[@Golfcartwhisperer]

@@JakeStoverOG do this here. Run you a jumper wire from main negative to the blue wire on solenoid small post but don’t touch it to the blue wire until you hit the gas. Tell me if solenoid clicks
