My modified ego2 is nearly ready to road test. I have installed an alltrax "axe" controller and have a question about pre-charge. The manual and wiring diagram show a resistor across the high current contactor poles. I understand that this is to keep the capacitors charged so they don't weld the contactor closed when I turn the key. My problem is that if I follow the wiring diagram explicitly, the controller will be connected (through the resistor) directly to the battery pack even with the key in the "off" position, and I don't like the idea of a current draw while the scooter is sitting idle.
I'm wondering if, since I won't be using "go far" mode with the alltrax controller, I could use the lead from the "go far" position on the keyswitch to pre-charge. Would I still need a resistor in the circuit? Could I turn the key to "go far" to pre-charge, then to "go fast" to engage the contactor?
Also, I'm having trouble finding a resistor locally with the values specified by alltrax. how critical is it that I match these values exactly(250ohm, 10watt)? if it's possible to use a different resistor, should I err for higher or lower impedance? higher or lower wattage? what would the effect be?
thanks in advance for any help.
