Curtis 1205 Controller Problem

Run 2 wires off NO terminal, green wire to J1 and another wire to J5 ?
Then jump from green/white wire from forward micro to common on reverse switch.

I am confused on how You have that wired.

The Controller J1 terminal needs +48v, if You ran that to the Throttle the Controller would Fry, so did You re-purposed the Green wire and it is not longer connected to the Black wire that goes to the MCOR?

Throttle Type=0 is a 2 wire throttle that only uses the bottom side of the MCOR, so that would be: Purple and Yellow to J2 and J3

I've been messing with this cart so long, I 'm starting to confuse myself.
This is how post 30 should read:

Since that post I was able to use 3 throttle wires. The green and yellow are wired opposite the wiring diagram. I now have green wire on J3 and yellow on J2 and purple to B- Red wire to J1. Throttle setting 1. Sorry to confuse.
Green wire runs from reverse switch to J3.
Can I run another wire off the same micro terminal with the green wire to J5 ?
Run 2 wires off NO terminal, green wire to J3 and another wire to J5 ?
Then jump from green/white wire from forward micro to common on reverse switch.

You either have a different Controller or different firmware and have been instructed directly by Curtis to wire it that way.

If either one of the above is correct, use your information.

However, if You are using the Controller I posted a link on post #10 (Curtis 1205M), Throttle types: 0, 1, 3, 4 and 5 are 2-wire throttles.

The original Club Car "reduced speed reverse" wiring circuit when using a 3-wire throttle inserts a 5.1kΩ resistor in series with the Top of the Throttle.

The reason for that is that a 3-wire throttle provides a "voltage" signal and not a "resistance" signal.

The 5.1kΩ creates a voltage divider which reduces the maximum voltage signal the MCOR can return on the yellow wire from 5v to about 2.5v.

If You re-wire the Controller to use the MCOR as a 5kΩ-0 (2-wire type=1), You need to remove that 5.1kΩ resistor from the circuit or you will have half of the throttle travel be a dead-band when on reverse.

If You re-wire it as a 0-5kΩ throttle (2-wire type=0), than the Green wire is not used at all and You could re-purpose it to bring +48v when the FNR is on reverse to Controller J5.

Is someone from Curtis telling you that you need to wire all 3-wires from the MCOR for throttle type=0 or 1?
