Well, let’s start at the beginning. What year 150 is this engine? Does it have the 35amp alternator, or the standard 12 amp system?
Did you check the charge coils with an ohm meter? Is there any chance that parts have been mismatched/swapped around? In other words, did someone put a 12 amp stator under a 35 amp flywheel or vica versa? It seems unlikely that both charge coils failed in the same manner, but anything is possible.
Like Frank says, meters are always suspect. All the settings changed in the late 80s, so it is easy to get fooled.
Finally, you mention isolating the powerpack stop circuits, I just want to ensure you did this completely. In other words, pushing both powerpack stop leads out of their rubber connectors. Simply unplugging the Big red connector will not isolate the packs from each other.
