Ohmmeter Readings for Operative
Components*
Zero ohms (continuity). Any other reading
indicates a bad switch.
No reading (open circuit). Any other
reading indicates a bad switch.
Zero ohms (continuity). Any other reading
indicates a bad switch.
No reading (open circuit). Any other
reading indicates a bad switch.
Zero ohms (continuity)
Any other reading indicates a poor ground
connection.
Zero ohms (continuity). If no continuity,
check wiring.
Zero ohms (continuity). If no continuity,
check fuse F1 and wiring.
Zero ohms (continuity). If no continuity is
found, check fuse F3 and wiring.
Zero ohms (continuity). If no continuity is
found, check for an open circuit and/or a
blown fuse.
Zero ohms (continuity). No continuity
indicates a bad switch and/or wiring.
180--2500 ohms, depending on engine
temperature. Zero ohms or an open circuit
indicates bad wiring or a bad switch.
12-volt relay: 85±5 ohms coil resistance
24-volt relay: 305±15 ohms coil resistance
Lower resistance indicates a shorted relay
coil and/or wiring. High resistance indicates
an open relay coil and/or wiring.
