Still have starting concerns for my '87westy.

A lot of recommendations to do a voltage drop test, between solenoid and positive terminal. How??? Is there a place to get extra extra long wires for my multimeter?

Volt test on battery looks good, but will like invest in a load tester also.

What grounds should I check?(where)

The concerns with a hesitation at the first crank. Then it starts. Once, only once, I drove around on errands and when leaving the last stop, it would not start. Heard a click, but nothing. No crank. I towed it home, checked it a few times and about 24 hrs later, it started no problem. Not sure what changed. 

Any ideas?
