Schematics/Electrical class taught at Fort McCoy Draw Yard
Students in the Schematics-Electrical class at the Fort McCoy, Wis., Draw Yard Jan. 25, 2022 learned how the positive and negative probes of a multimeter are inserted in the brass-lined pins of this Light Medium Tactical Vehicle’s Electronic Control Module. This would be the case for checking resistance or ohms. To check voltage, only the positive probe would be inserted in one of the pins. The negative probe would be connected to a ground.
