I don’t recommend for people to
The starter has two wires connecting to it. The large one from battery and the brown wire going to starter relay.
Unplug the brown wire from starter relay. Gently pull the brown wire out and towards the battery. Take a small screwdriver and insert into the back side of the brown wire connector (not the plug in part – for that will bend that part out of shape). Touch the small screwdriver/connector to positive battery post.
Much safer and does the same thing.
If battery is charged – but it doesn’t crank over, then 99.44% chance it’s a bad starter.
*** Note: 99.44% is some random number I came up with - that may or might not be correct.
