Electrical System and Transmission Weep Hole Check

What happens here

Inspect the electrical system for proper functioning, particularly checking if the alternator is charging the battery. Use a simple $6 voltmeter to test the charging output on the alternator wire. Check for a 'weep hole' at the bottom of the transmission, which should have a small cotter key hanging out. If this cotter key is missing, it suggests that someone has worked on the transmission, and you should inquire about the nature of those repairs.

Goal: Verify the electrical charging system and inspect for signs of transmission work
