Signal Too High. Permanent Fault
Signal too high. Permanent fault
Checking the contact reel
Check that the upper connector on the switch for the cruise control is correctly connected.
Disconnect the upper switch on the switch for the cruise control. Take voltage readings between terminals #B1 (26) and #B3 (28) (on the cable connector). If the voltage is approximately 12 V the fault is probably in the switch for the cruise control.
Remedy as necessary.
