Not having a speed sensor is the issue with your current (DCS) motor.

The XCT-PDS controller uses the motor RPM information provided by the speed sensor to optimize the field mapping and regen braking and max RPM limiting. Unlike the stock PDS controller the XCT-PDS will run more than just at low speeds without a speed sensor, but it runs slower than it does with a speed sensor and doesn't have as much low end torque.

A XCT-DCS is designed for the DCS motor and will perform better with the motor you have than an XCT-PDS, but the jacks on a XCT-DCS don't match the plugs on a PDS wiring harness. However, a PDS to DCX wiring adapter adapts the PDS plug to fit a XCT-DCS controller. The problem being the XCT-DCS doesn't have a jack for a speed sensor if you or some future owner decides to upgrade the motor and all aftermarket sepex motors have speed sensors

Basically it is a Hobson's choice situation.

As JohnnieB suggested I would get a new motor w/ a speed sensor and go back to the PDS wire harness. Sounds like someone had a DCS motor kicking around and slapped it on the cart. Not hard to come by DCS motors... I have a DCS motor sitting in my garage with no home. I also have a PDS motor keeping it company with no home... 5kw AC motor is replacing it. :D

All DCS (and PDS) cars i've seen have shunt wound, not series wound motors, where the 'S1' and 'S2' say 'F1' and 'F2' instead.

DCS was EZGO's first attempt at a regenerative braking golf car. a series wound motor is incapable of regen braking. I don't even know what would happen if you put a series wound motor in a shunt wound car.

I’m thinking I’ll just get it running for the summer and tear it all apart and replace a lot of things and go with an upgraded motor this winter. I started going through all the wiring yesterday and see what all for sure is damaged. Have to test all the switches and start ordering more parts.

The DCS sepex motor had studs labeled S1 and S2 that were the same size as the A1 and A2 studs, so they can easily be mistaken for series wound motors. In fact, when a DCS motor is mounted, there is no way to tell if it is a series or sepex except by the part number.

I checked the part number given in Post#1. The OP has a DCS motor.

So what would be a good motor to look at for a future upgrade. Will be ridden on paved roads small to mildly steep hills.
