Tapping this start button wire to ground will (should) activate the starter solenoid to engage the starter. That's how I start my tonner pickup because the button is all corroded. Next, with the big battery-type cable from the solenoid to the starter disconnected, you should hear a pretty loud click coming from the solenoid when the start button is grounded. It will 'unclick' when the start button wire is no longer grounded. I usually tap the start button wire to ground and the solenoid should be clicking along with the taps. These should test both the start button and the solenoid. Does your solenoid have the handy little button on the bottom to activate it from under the hood? Sometimes these tend to stick. Napa has lots of good solenoids in stock. Wish I could get away and sneak over to Bellingham.....
