1970 Chevelle 396 HEI Ignition No Spark

Thank you for the information Bewy. I will test the pickup with a multimeter and see what reading I get. MV8, this was converted to HEI from points a while ago by a shop. I'm not entirely sure if it'll spark/run if a jumper is added to the HEI directly from the battery. Should I try to get a long alligator clip and connect one side to the positive of the battery and the other side to the BAT connector on the distributor? Thanks guys
