they dont think it
now its narrowed down to bad connections and/or bad battery terminals. pics of the ring terminals and battery terminals would help, as would pics of the ground locations themselves.
first step is to set the meter to ohms, and most are marked with a setting called "10" or something similar...set it to that. measure from the negative battery terminal to the chassis ground...battery terminal to the transmission ground...battery ground cable end-to-end...and so forth. cheap meters from harbor freight or menards will only go down to about .5 ohms or so, which is ok. thats close enough to 0 as long as we know that it can't actually display 0.
next is to switch the meter to DC voltage or some are marked just DCV, again to the "tens" position. might as well measure across the battery terminals to start, making sure we have 12.8v or higher with the car off, and it should show 13+ with it idling. once that's done, start probing the grounds with the black lead while holding the red lead on the positive battery terminal. if you see a spot with low voltage, there's your problem. alternately, use the resistance setting and do the same.
