a question and a big boo-boo to report.
first, did the post #'s change? my notes say post#3365 should start a pre-charge resistor conversation and it doesn't seem to be there. same with other post#'s. ???
second, i hate to admit it but i shorted the controller across b+ and b- connections. the caps were charged and i touched them with a wrench i was holding. it literally sounded like a gunshot and i thought i fried my cougar. it really sounded like something blew up but there was only a small scorch mark on the b- , the controller had no visible damage and it has since been operating normally. i think i might have blown a finger off if i had touched shorted these with my hand. i think i might have croaked if i had shorted these with 1 hand on each of these (through my body).
EVERYBODY BE CAREFUL WITH THE CAPACITORS! I plan on adding a 115v bulb across here so the caps will drain after my contactor opens. I'm looking for the posts where someone describes their precharge setup using a 115v bulb.
