Safety With Starting and Charging Systems



Keep these 9 safety precautions in mind when working with starting and charging systems.

---

1.  When testing a starter on a “free speed test,” make
     sure the starter is fastened securely to the bench.
     A great deal of torque is usually produced when
     the starter first begins to spin.

2.  When working on the starting or charging circuit,
     always remove rings, bracelets, and other jewelry
     to eliminate the possibility of getting an electrical
     shock.

3.  When removing a starter, first disconnect the
     battery terminals (negative first) to eliminate the
     possibility of accidental arcing from the battery
     cable to ground.

4.  Often the pinion gear on the starter or the flex plate
     ring gear is worn and has very sharp edges.  Be
     careful not to cut your fingers on the sharp edges
     of a worn gear.

5.  Some starters are quite heavy.  When installing a
     starter, be careful not to pinch your fingers between
     the block and the starter frame.

6.  On many alternators, the hot (+ battery) wire is
     connected to the back of the alternator.  Be careful
     not to have the air cleaner or other grounded
     component or tool touch this hot wire.

7.  When tightening the belt on the alternator, always
     watch your hands so they do not get pinched or
     caught near the belts.

8.  When removing an alternator, always make sure
     the battery is disconnected.

9.  Always remember to wear OSHA-approved safety
     classes when working on the starting or charging
     system.
