Re: Ezgo Model 830 3-wheel cart- new to me and too slow...
I couldn't believe my eyes when I saw the pictures.
We have one of those death traps at work. It will haul two fat guys across the flat concrete at roughly 8-10 mph. At night, you can see the halo of blue sparks coming from the motor underneath. I swear it's only a matter of time before we burn down the entire airport. |

Re: Ezgo Model 830 3-wheel cart- new to me and too slow...
No blue sparks yet, but I'm trying!!! I'd love to see 10mph out of this thing with just me on it.
To upgrade to 36v... I only have room for 4 batteries. Would it be best to go with three high quality 12v deep cycle batteries, or is it possible to run 2-12v deep cycles with 2 of my existing 6v batteries so I have more overall AH capacity? |

Re: Ezgo Model 830 3-wheel cart- new to me and too slow...
check solenoids first if they are 24v then it would not work
i would test each one to ensure they are all working repair coil then see what your speed is again you can't mix batteries 3 x 12v batteries might work if solenoids are 36v |

Re: Ezgo Model 830 3-wheel cart- new to me and too slow...
Looks like the solenoids are marked 24v on the end, so buying 7 new 36v solenoids and batteries starts to look like a major investment on what started out as a cheap cart...
So I don't keep tying everyone up with rookie questions, is there any type of simplified explanation of how the system is supposed to work? I have the wiring diagram, but I honestly don't understand how it's designed to work (where should I see voltage during testing, what do the 4 different connections on the motor do, etc). Is there some type of basic explanation out on the web that explains how it works and basic troubleshooting? Thanks again for your patience! |

Re: Ezgo Model 830 3-wheel cart- new to me and too slow...
basically its key supply's power to go pedal ... pedal activates the solenoids one at a time they run power through the coils which burn off power to make speed slower when pedal is full no coils are used and you are at max speed
the key switches forward and reverse the micro switches in the pedal box tell solenoids to close allowing current to flow to motor the 4 post on motor make it go forward and reverse first fix your coil solenoid test Quote:

Re: Ezgo Model 830 3-wheel cart- new to me and too slow...
resistor coil is fixed... Was able to slot the remaining connector piece and reattach. See pics. Seems to drive the same as before, but now its now bouncing around loose...

Re: Ezgo Model 830 3-wheel cart- new to me and too slow...
Any chance it could be converted to a conventional resistor cart with a more robust wiper board and a single solenoid? It would allow 36 volt operation, which "should" result in a 3/2 increase in speed.

Re: Ezgo Model 830 3-wheel cart- new to me and too slow...
I'm all ears on potential options to upgrade. I'd really like to figure out how to get it to 36v without breaking the bank...

Re: Ezgo Model 830 3-wheel cart- new to me and too slow...
OK. Quick update... Removed all the wiring and tested each solenoid. They all worked fine and had good resistance readings across the main contacts when closed. Main Resistor bank is also fixed. During the solenoid testing, I managed to damage one of the small resistors that is connected between the control posts on the solenoids. What are these resistors for??
After putting it all back together it runs about the same. No faster... The 1st solenoid engagement is fine (fwd or reverse??) but the 2nd click causes the car to "jump" into motion. Is this because of the resistor? Also, still seems like the "3rd speed" solenoid has no effect on speed, and it also does not engage unless I hold the pedal down hard to the floor and it will click on and off if I move at all. Is there an adjustment for the pedal when the solenoids engage? Appreciate any suggestions... Thanks |
