I did all the above and if I take a jumper cable and go straight to the starter it will work. . But if I go thru the solenoid I have 12 volts on the main lug until the solenoid energizes.
The starter solenoid has power on the main lug from the battery, as soon as the solenoid engages you hear the click but then I lose my 12volts on the main lug. Any ideas about where to start?
