Re: Identifying 2000 TXT EZGO Model, Increasing Speed/Torque, Fixing F/R switch
You can fix your F/R switch with a couple micro switches. Or with a DPDT switch. Or you can in stall a reversing contactor and a switch on the dash for your Forward and reverse
Some of our sponsors here sell the reversing contactor http://www.buggiesgonewild.com/site-sponsors.php Quote:

Identifying 2000 TXT EZGO Model, Increasing Speed/Torque, Fixing F/R switch
Here are pics of the controller.
Seems like a Curtis replacement for this one: https://www.golfcartking.com/ezgo-tx...-oem-73144g06/ So definitely a DCS. Based on reading around the forum for previous successful DCS upgrades, it seems like my upgrade path will be: Phase 1: - Reverse contractor or DPDT (does it matter which when a beefed up controller/more amperage is in the near-ish future?) - Replace drum brakes or upgrade to disc (need to check that the current wheels have the clearance for disc kit). Currently the cart does not stop fast enough to safely add more speed/torque - DC step down converter that supports 36 or 48V pack Phase 2 (ScottyB order): - New 2G or 4G cables. - Replace any other cables that are in bad shape (research what gauge to use) - Alltrax 400 controller & solenoid - Better state of charge meter - show only voltage no LED bars (maybe one that can take 36, 42, or 48V?) I have a feeling this will provide sufficient power, if not, increase voltage/pack upgrade to 48V (maybe lithium?), and potentially a new motor. In terms of older components wearing and not handling these upgrades well...Should I be concerned with anything in particular or validating/replacing preventively other than brakes? Thanks for the continued help, exciting times. |

As for brakes yours probably just need adjustments. Take the hubs off and clean everything. Make sure the star wheels can turn freely. Tighten them to where you can barely g3t the hub on and reassemble. Once back together pump the brake pedal as hard as you can and it should finish adjusting. |

Reversing contactors are for Series Drive carts and you have a Sepex Drive, so a DP/DT-center off switch is the only option other than the OEM hockey puck system. Attached is a drawing of how to wire switch. Dick brake kits need 10" or larger wheels. Drum brakes are okay if they are in good health. Also, they have some help from regen braking in sepex drive carts. Phase-2: Replace all 10 high current cables. 2Ga is better than 4Ga. Unless the insulation is worn, the OEM F1&F2 cables are adequate. The fan is an option on the XCT48400-DCS and standard on the XCT48500-DCS, so check the pricing with fan. An XCT controller work at 36V, 42V and 48V. So does a MZJ400 solenoid. In other words, those two will run at 36V now and 48V later. A DVM type battery meter will work for any voltage from about 7V up to 99V, or so. The stock DCS motor has good torque. Get the rest of the cart set up the way you want it and then go with a motor based on that setup. |
