Step 15. Dial 89 into TEST SELECT.
Measure voltage drop across each cable connected between batteries,

Do this by connecting test probe cable W2 clip test leads across ca-
ble to be measured.
Step 16.
Press and release TEST button.

terminals that cable was connected to and cable terminals .
Reinstall cable and repeat above test. If VTM still displays
over 0.2 volt, replace cable (page 5-158).
b. If voltage drop is less than 0.2 volt, check for loose or corro-
ded connection between starter solenoid MTR terminal and starter
motor positive terminal. Remove connector between these two
terminals and check for dirt or corrosion.
Dial 89 into TEST SELECT.
Measure voltage drop across each cable connected between starter
