If I upgrade to 42 volts do I leave the solinoid hooked up the stardard way? I know I will have to add a 6 volt charger and move the standard charging system to only charge the 36 volts. will the 36 volt HD solinoid work. I am running a Beast motor and a 650 alltrax controller w/ 2 Gauge cables throughout. Plenty of tourqe but NO speed. Hopin the extra 6 volts will do the trick.
