Cable Test

The resistance of any cable can be checked in the same manner by using Rotunda 73 Digital Multimeter (105-R0051), or equivalent.

1. Determine which way the current is flowing in the cable. Connect Rotunda 73 Digital Multimeter (105-R0051), or equivalent, positive lead to the end of the cable nearest battery positive. See WIRING DIAGRAMS  .
2. Connect multimeter negative lead to the terminal at the other end of the cable.
3. Crank the engine and observe multimeter. The voltage reading should be 0.2 volt or lower. If the voltage drop is too high, clean the terminal ends. Retest, and if still high, replace the cable.
