Communication Failure Causes
1. Damaged power supply, check for 21-25 volts DC
2. Water inside power connection to motor box,
check seal at motor box and for breaks in
flotation hose
3. Damaged flotation cord, check for ohms reading
of .4 to .8 ohms
DC voltage test on power supply
21 to 25 volts dc is acceptable. The power
supply is not repairable and must be replaced
if defective.
Insert voltage probes in pin terminal 1 and 2 and
turn on power supply to test.
Flotation cord test. Remove cord from
motor box and check ohm’s reading
between each pin and wire end. .4 to
.8 ohm’s is acceptable.
