Thanks guys...I don't think it's the IC. I completely disconnected it, and I'm getting the same readings at the fuse box.

Fuses B1-B4 are not routed through the ignition switch I've found, and are live 12V, fed from the power distributor. I'm getting a reading of 11.7V at B1 and B1, but I'm not getting any reading at B3 and B4 (numbers on my meter are jumping all over the place).

I think there's something between the power distributor and the fuse box, or perhaps at issue at the fuse box itself.

There's also a relay indicated in that circuit. Does anyone know specifically which relay that is, and its location?
