2000 Ezgo TXT pds wiring question

[ebro]

Hello, I am looking at the PDS wiring diagram from cartaholics and there is a wire shown that i do not have. It shows 4 wires coming from power harness going into the top of the controller..F1, F2, B-, and A1. The only wire I have on B- is the wire to the - terminal on the batteries which is shown separately so this cant be what they mean. What is the additional wire that goes to B-? could it be a ground wire? Help and thanks.

Interestingly some ezgo carts produced between 2000 and 2001 can cause confusion due to their mixed components. These particular models may feature an F&R switch that resembles the DCS system but are actually fitted with a 10-pin PDS controller. This anomaly can lead to misunderstandings when trying to identify the correct system. The PDS, a more advanced regenerative system developed, offers greater flexibility allowing the adjustment of performance settings using interchangeable "chips" or Molex connectors, which was not possible with the DCS system.

To determine whether your ezgo golf cart is a Series or Sepex (regenerative braking) model and, if it's Sepex, whether it is a DCS or PDS version, you can follow this attached guide with pictures for clarity.

For identifying Sepex (Separately Excited) carts, the key components to examine are the controller and the Forward & Reverse (F&R) switch. The DCS was ezgos initial leap into regenerative braking technology. This system integrates regenerative braking but is known for its limited modifiability; altering or bypassing the regenerative feature requires replacing expensive parts. DCS carts usually have an F&R switch that appears similar to those in non regenerative carts, but they are equipped with a distinct controller specific to the DCS system.

The PDS is ezgos subsequent regenerative system which allows for more flexibility and programmability. PDS carts can be configured with four different levels of regenerative braking via specific "chips," which are actually Molex connectors with different wire loop combinations. These chips allow users to select various performance parameters to suit their driving preferences. Hope this helps clear a few things up for you, if you need further assistance feel free to ask!
