Just a note on multimeters, too: make certain you remove at least the negative lead from the battery before you ohm out anything, especially is you leave it in-circuit while testing. The slightest current that passes through the meter while testing can blow the meter's ohms portion. Most meters have a fuse protecting the ohms section, but not all do. Something to bear in mind.

Also, yes, you can slide the meter leads into the back of the connector without hurting anything. Alternatively, you can take a very small piece of solid wire, and slide it into the connector's rear, and the touch the meter lead(s) to that. Whatever you use, just make sure it touches the metal pin inside the connector. Not some piece of insulation, or connector plastic. No damage should be done the connector, as long as no excessive force is used at any time.

Good luck to both of you.
