Electrical Problem?

Hello,

I have a 94 F150 302 that won't turn over. The problem started by slowly turning over for 2 days then the nothing. I pulled the starter and had it tested (it failed) and I replaced it. The battery was also dead (parasidic draw?) so I replaced it, the solenoid switch on the fender wall, and the alternator as well. It started and all was fine. While the truck was running I pulled the negative battery cable and the truck shut off. Thinking that the alternator was bad I pulled it and had it tested it passed so I put it back in. I crossed the solenoid switch and it started and discharged the battery so I replaced the battery again. I also replaced the pos and negative battery cables as well as the fusible link to the alternator and the 14awg wire from the solenoid switch to the stater solenoid. I have checked the continuity of all fuses and triple check all the cables as well. There is no power in the cab. Could the igntion switch be causing a problem? Any suggestions would help

Thank you,
Jonathan

Pulling the neg cable while running disabled the computer, coil etc so she died. Maybe check the relay or fuse to regain power.

Not an expert but there should be some fusable links in the bunch of wires that connect to the big terminal on the fender mounted starter relay, you may have one of those blown.

can you get it to run and then test the leads on the alternator to make sure the power is getting out of the alternator to where it needs to go?
