5. Engage the remote starter switch. Read and record the voltage. The voltage reading should be

0.5 volt or less.

6. If the voltage reading is less than 0.5 volts, go to the Starter Motor-Ground Circuit Component

7. If the voltage reading is greater than 0.5 volts, this an indication of excessive resistance in the

connections, the positive battery cable or in the starter solenoid. Move the Digital Multimeter

negative lead to the starter solenoid B-terminal and repeat the test. If the voltage reading at the

B-terminal is less than 0.5 volts, the concern is either in the connections at the starter solenoid

or in the solenoid contacts. Go to Step 8. If the voltage reading is greater than 0.5 volts at the B-

terminal, the concern is either the positive battery cable or connections. Go to Step 9.

8. Remove the cables from solenoid B-, S- and M-terminals. Clean the cables and connections

and reinstall the cables to the correct terminals. Repeat Steps 3 through 6. If the voltage drop
