I've inherited a PGM III of unknown status. What is the best (and safest) way to determine if it is working? (stock loom except for wire splice) I've read about how things like frozen power valves can blow PGMs, but I'm wondering about the other direction, if popping this in can possibly blow something downstream. Do I just put it in and see if the bike starts/runs or is there more to it than that? Thanks for any help. Happy New Year.
