So I know it's a dumb question but here goes I dual motors and batteries as well as throttles. When connecting battery to controller you get the spark right? Well one battery does the other don't, I've changed bms went from 52v to 36v I get voltage from charge and output wires but plugging to controller of either gets no spark using xt90 for connecting any speculation is worth trying because it was working...HELP oh using 18650 cells 7a max 2.5ah nominal don't that matters just through it in for reference.
