Intermittent Operation
- Check solder connections at relay switch and terminal board. Connect wiper to operate in low speed. Connect ammeter (range 0-30 amps) in feed wire circuit to wiper and observe current draw. Allow motor to run until it becomes hot.
- If current draw is normal and wiper cycles on and off, a weak circuit breaker is indicated. Replace brush plate assembly. If current draw exceeds specification, adjust armature end play and recheck current draw.
- Adjust gear assembly end play and recheck current draw. If adjustments fail to correct excessive current draw condition, disassemble motor section of wiper and check armature on growler for shorted or grounded condition.
