Default 1204 controller, half-speed forward full speed reverse

New 1991 ezgo with 1204 controller has issues. What can be done to reverse this condition without swapping wires on the F/R or S1 and S2 on the motor?
This controller does not have the 4th wire (orange) to unplug as the 1205 does. Another thread mentions swapping the 2 wires on the F/R but that the handle position is reversed.
Thank you.

I was hoping that might work but wanted confirmation from an expert first.
Thank you for the response.

Swapped the leads S1 and S2 at the motor but handle positions are reversed as I suspected they would be. Also the buzzer is annoying!
Thank you or your input anyway.
What actually controls the 1/2 speed reverse mode on the 1204? Would reversing the 2-pin connector on the controller have any affect?

Leave the S1&S2 switched and now switch the A1&A2 leads. That should get the F/R switch and motor direction back in sync.

If your Marathon has a pot-box type throttle, disconnect the two wires between the pot-box and the F/R assembly to get rid of the 1/2 speed.

What happens is that a microswitch on the F/R places a 5K fixed resistor in parallel with the 0-5K pot, so the controller only sees 0-2.5K rather than the normal 0-5K.

Thank you for the explanation regarding the pot box. Just what I wanted!
I did return the S1 and S2 to their original positions so I will leave the A1 and A2 alone. I will disconnect the 2 wires between the pot-box and the F/R assembly to get rid of the 1/2 reverse speed to simplify matters. Evidently the micro is defective?
I'm really not interested in 1/2 speed!
Thanks again for the explanation,
Dennis

After all that, the micro is ok, I reconnected it and 1/2 speed reverse, removed it and full speed reverse just as it was explained by JB. Don't know what the real problem was but it was way torquey/speedy in reverse, and now it is working as it should! May be an intermittent problem.
Thank you
Dennis
