Dave AI2V is correct, the negs go to B- not chassis ground. Usually the clue is that the cap can is isolated from the chassis either by a non-metallic mounting wafer (twist on cans) or a cardboad or paper insulating tube around the can (clamp type). Manufacturers would not go through the added expense of isolating the cap only to wire it back to chassis. PL
