FINAL DRIVE AWD Diagnosis Symptom: AWD Will Not Engage 1Check the gearcase coil resistanceTo test the coil resistance, measure
for minimum battery voltage at the Gray and BrownWhite chassis wires that power the coilA minimum of 11 Vdc should be presentIf
electrical tests are within specification, remove gearcase (see "Gearcase Removal") and inspect componentsInspect the armature
plate for consistent wear patternThere should be two distinct wear bands (one band inside the other)If only one band of wear
is present (or if there is wear between the two bands), inspect the coil area as indicated in Step 5A wear band with an interrupted
wear mark may indicate warped plate, which may cause intermittent operationSee the following illustrations: Check for wear
bands Inspect the rollers for nicks and scratchesThe rollers must slide up, down, in and out freely within the roll cage
