1984 Ford Econoline E150, Van Display Extended, 5.8 HSECTION Control Switch
- Disconnect 6-way connector at amplifier. Check battery voltage at Light Blue/Black dashed wire when "ON" switch is depressed. Battery voltage should be available from Light Blue/Black dashed wire leading from control switches.
- Connect an ohmmeter between Light Blue/Black dashed wire and ground. Check wire for continuity to ground with "OFF" switch depressed. If resistance higher than 1 ohm is found, the wiring, slip rings or switch is at fault, or steering column may not be properly grounded.
- To check steering column ground, connect an ohmmeter between a good body ground and steering column upper flange. Resistance should be less than 1/2 ohm. Rotate steering wheel, and check flexible coupling for resistance less than 1 ohm. If resistance higher than 3 ohms is noted, clean horn brush contacts and ground brush.
- A resistance less than 1 ohm must be obtained before performing remaining tests. With ohmmeter connected between Light Blue/Black dashed wire and ground, depress and hold "SET-ACCEL" switch. A reading of approximately 680 ohms should be indicated on ohmmeter.
- Depress and hold "COAST" switch, a reading of approximately 120 ohms should be indicated on ohmmeter. Depress and hold "RESUME" switch, a reading of approximately 2200 ohms should be indicated.

- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
