Replacement controller for XB-500 shunt mod help

I toasted my old controller in a stupid way. doh!

I recently purchased a new controller for my XB-500 and it has a different case (larger) and the PC board is mounted in such a way that the MOSFETs are secured with screws that are not easily accessible.

When the end cover of the controller is open, there is a large resister where the shunt wire was on the old controller. I do not know if this is a replacement for the shunt wire or if this is a totally new PCB design.

  1. Any one have any ideas?
  2. Has anyone shunt modded a replacement controller?

I ordered the controller directly from Xtreme which directed me to Green Max Distributors Inc to complete the purchase.

I am inclined to try to rip the new controller apart but I need the scooter with the better weather ahead.

All I need is a little more power on hills, not any more speed.

Thanks

I think I figured this out.

The controller appears to be the same one the is used in the XB600 and the mod instructions for the xb600 shunt looks like the correct mod.
