I have a 1999 CC regen 2 cart. My question is...I am replacing almost everything on the cart and I upgraded to 2 heavy duty solenoids with diodes and resistors on each. On my cart, the main solenoid has an "energy displacement coil". Do I need this coil if I am running a resistor and diode on the solenoid? My guess would be yes...but I just wanted to check with people who know much more about these things.
