Orange Truck in Winter Snow

Last week, Bruce Purkey shared with us some tips and best practices for readying the tractor for winter. In his webinar, Bruce referenced the Technology Maintenance Council (TMC) RP-129, which outlines an easy 1-2-3 approach to testing cranking and charging systems.

Testing the Cranking System

  1. Disconnect all batteries and test with a quality tester
  2. Conduct a voltage drop test on main cranking cables
  3. Conduct a voltage drop test on the control circuit

Testing the Charging System

  1. Take all batteries apart and test with a quality tester
  2. Conduct a voltage drop test on charging cables
  3. Test the alternator
