Agreed on the Trojans. (Can I borrow them for a week to experience what I'm missing?
)
If the contactor controller isn't totally fried, I'd at least want to try it before yanking it out to put in a PWM unit. More than a couple of people who have owned these cars on the EVDL weren't completely happy with the "upgrade". One guy even reverted back the contactors.
Plus the contactors are 100% efficient, which is nice. Anyway, you probably know all this already.
