Ignition switch connection

Did you check the infeed to the switch with the switch powered on? Also did you check both the key side and harness side of the switch connector? If so and that shows no drop, then it surely is in the switch--not really uncommon. One way around this is to put a couple of relays in there.........one to fire accessories and one for the IGN1 feed
The volt was checked w power to switch. Only checked key side of connector for ign1 &ign2 since it showed the 1.5 v drop coming from switch. If I get switch connection good then I'll check both sides of harness connector.
