Since you have ruled out the batteries and connections the next place to look is the starter assembly.
A failed hold in winding in the solenoid will cause those symptoms.
The solenoid has two coil windings used to pull the solenoid plunger and close the switch. The pull in winding is usually the heavier of the two. It is connected from the S terminal to the starter terminal and is grounded through the brushes and armature. The hold in winding is connected from the S terminal and grounded the the solenoid case.
When you apply power to the S terminal both windings work together to pull the solenoid plunger into the solenoid. Once the plunger mover far enough to engage the switch both sides of the pull in winding will have battery voltage applied to them and will no longer exert any electromagnetic force. The hold in winding is left to keep the solenoid plunger in the engaged position. If the hold in winding is not working the plunger spring will push the plunger back out of the solenoid as soon as the switch closes. When the switch opens the plunger will again be drawn into the solenoid.
Th check the solenoid winding disconnect the solenoid terminal that is connected to the starter. Then check for continuity between the S terminal and the stater terminal and also between the S terminal and the solenoid case.

Some have been very good, some have been well, disappointing to say the least. But no matter how good or bad auctions may be, we always seem to stay until the item we've come for or are interested in is on the block. I've been to some auctions near and far. I think the furthest has been the Two Cylinder 7 in the Amana Colonies last year. Lots of stuff, lots of people. I've also atten
