b. Connect a suitable ohmmeter between terminals SPD (+) and SPD ( - ), Fig. 27.
c. Revolve meter shaft, then check that indicator repeatedly deflects from zero to infinity.
2. On digital meters, proceed as follows:
a. Remove combination meter with connecting wiring harness.
b. Turn ignition switch ``On.''
