Have you tried switching it back? Removing powermax 3?

No, I haven't ctried swithchiung back yet, that's a lastr resort. It seems to me something in commen with all these devices is wrong. I am going to recheck my fuses and connections. Thought I read about a similar problem at one time, right now I am stumped though.

Sounds like an open circuit on the run side of the ignition switch. I don't know how power max hooks up. maybe you disturbed the connector on the switch.
