Installed 3 output isolator. Per instructions removed and bypassed the solenoid connection to go directly from Alternator B+ to isolator input. House battery began to discharge rapidly so I disconnected the new connection. One possibility is the alternator B+ wire was crimped with the ignition switch wire. So I think I should separate the B+ and ignition leads. Then reconnect the B+ to isolator input and reconnect ignition wire to solenoid. Agree?
