The controller is a 450 amp series controller which is what your Medalist would use. The only thing I'm not sure of is the throttle input (the last 2 digits "04"). The data sheets on line don't drill down far enough, you will need to call Curtis to find out what input it has.
Keep us posted on what you find so we all can learn.
Thanks for the heads up HRC but I'm still confused or maybe just blind.
The data sheets I looked at only take the model down to 1204S-54xx, with no designation for the xx digits.
My thought is the last 2 digits indicate the throttle input.
I agree the standard input is 0-5K but it also says "Standard Throttle Input: 0-5k ohms ±10%
Is there a way to determine what these last 2 digits mean?
can you post a picture showing the conection area?
if it has three big hook ups on the top and the one in your cart now has 4, you can eliminate the short A2 wire from the F/R switch to the controller. Then you just need to be sure the small wire hook ups are compatable (same number of pins to wires ect...)
If I understand you right, this is what you are wandering?
Someone double check me on that info, I don't want to lead you astray
