I’m trying to figure out which two sockets of the four to my IMA battery, thru the wiring yoke of my Maxxvolt charger are the main leads to the battery. This so I can wire my discharge load thru the yoke. The four are in a female nine pin socket and numbered 3, 1, 4, and 7. Will my volt meter only read voltage across the main leads or will it show voltage across to the fan leads as well. Max volts was reluctant to tell me for warranty and shock risk reasons. Though I saw the plug solution as less dangerous than going back to the open battery and splicing wires. Does anyone out there know which of the sockets are the right ones?
