Do you have the vacuum wiper motor connected to the intake manifold? Bad hose or vacuum motor? Do you per chance have hyd brakes with a vacuum booster? Had a vacuum booster go bad for me.

You should not have a voltage drop across the ign switch. Use find sand paper on the contacts and then apply dielectric grease.

Also, you have run a ground strap from the frame to the motor. Is the battery grounded to the frame?
