What's the easiest way to check if all your ground in your car is properly attached? (not necessary related to cars).

Digital muti meter set to read ohms. the lower the number the less resistance the better the ground.

just out of curiousity - what to spots would you probe? Specifically - what resistance would you be measuring?

there wouldnt be any resistance to measure if he is measureing ground.. lol

I would measure for a voltage across positive and negative.. then measure drops using your specified ground area or a diffrent ground area...

and you never want to be measureing ohms of ANY power supply either! lil fuse inside the meter will go POP!

Marc is correct, if he is measuring a spool of wire, or a isolated circuit without a pwr supply.

to check ground paths, Probe Bat - to alt case. bat - to chassis, alt case to chassis. Amp - to chassis. - amp wire to chassis. You want a low reading on these as possible 0.00 is perfect. If you get readings over 1.5, redo the connection. Aslo engine block to chassis. Mine was at 4.6. The strap was intact. I gust ran another piece of 4 awg piggybacked on the same mountings. :-)
