Re: 1998 EZGO TXT help needed

Motors operate over a wide range of voltages and a stock 36V DCS motor is happy at 48V. Get a super-duty 48V solenoid (MZJ-400), it operates at 36V, 42V and 48V. It also passes 1000A peak and 400A continuously, which is adequate for use with almost all controllers. 2. Unless the two thinner ones are damaged, they don't need to be replaced. All ten of the high current cables need to be replaced. 3. 2Ga cables have 59% less resistance than 4Ga cables, so less energy is lost to cable heating. However there are only about 15' of high current cables total in a DCS cart, so the power loss is fairly low. Specifically, ~37W for 4Ga vs ~23W for 2Ga. 4. The opening in the bottom of the cover has to be enlarged for the larger cables. However, this becomes a moot point if you install an Alltrax controller, the cover is not used with them. |

Re: 1998 EZGO TXT help needed
Thanks for the great info.
So the ten cables to replace are the five between the six batteries, the positive and negative to the controller and solenoid, and the two to the motor. What is the tenth? Is there another from the solenoid to the controller? JohnnieB, I don't understand your comment about only being 15" of high current cables in a DCS cart. Are you saying that I can make that cable bigger and the others smaller and get the same result? Thanks |

Another question, if the battery tray is designed for six batteries, where do you put the other two batteries when you go to 48V?

Note, the cable to A2 on the motor isn't connected correctly on the DCS schematic. I ought to go between the controller's B+ and A2 on motor. The short cable from the solenoid is also connected to the controller's B+ terminal. Electrically it appears to be the same point, but it actually isn't since armature amps are greater than battery amps when the controller's output is less than 100%. 2. Oops, I fumble-fingered the keyboard. I corrected it. DCS (and PDS) carts have a total of roughly 15 feet of high current cables. The max current flow on all ten cables is the same, so they all ought to be the same gauge. All cable(s) thinner than the rest will be a choke point for the system. 3. There are more than one way to skin a cat. Some people put the additional two 6V batteries in the bagwell. Some shoehorn all eight 6V batteries under the seat. Others use six 8V batteries to get 48V. While others only go to 42V and the seventh battery fits nicely in front of the driver's side rear wheel well. |

For the reverse switch. The only thing I had to do is replace the micro switch on the reverse side of my lever. When I would shift to reverse it would not always give me the reverse tone and would not backup. New micro switch fixed that issue. It was inexpensive. I understand the Micro switch was a weak link in th DCS carts... Skip Sent from my Nexus 6 using Tapatalk |

Re: 1998 EZGO TXT help needed
I also went with 2GA cables instead of the 4GA... The cost difference is not that much... Do the 2GA...you want a cart that is efficient as possible.
