Starter Button NOT!
Thanks everybody for your reply. I had reworked the harness six months ago, so, I was fixated on the button. But, when I removed it, touching it's two wires caused nothing! Hmmmm. Turned out it was the fuse holder to the starter solenoid that, evidently, was barely making contact. When I checked the fuse, the wire from one end of the holder came loose. I changed the fuse holder using a "beefier" spade fuse model and all works great. I'm going to order a spare button anyway. Thanks again.
