That was one of my points. You can tighten the bolt 'til the cows
come home but if it isn't squeezing the post, it won't work. But if
you have frayed wire at the terminal to cable connection, you're
losing current there and the terminal should be replaced.

If you can apply a load away from the battery, such as from the frame
to the starter or its relay, a voltmeter will reveal any voltage drops
across poor terminal connections. Several amps of charging current may
be enough, too.

A headlight bulb draws around 5 Amps.

Yeah, headlights were an easy test for a charging system, too. Start
it up, remove a battery cable, then turn on the brights. The engine
will die if the charging system isn't working properly.

Its also a good way to kill an alternator on some vehicles.
