I'm having problem with a starter motor on a riding mower, and need to check if the motor is getting juice and not working or if something else isn't working and no juice is getting to the starter.

Measuring resistance doesn’t seem to be a big deal. Put your meter leads across two wires or terminals and read the value, right? Most of the time that is good enough, but sometimes you need better ...
