Testing Power Supply & Flotation Cord 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 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. Insert voltage probes in pin terminal 1 and 2 and turn on power supply to test. 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. Page 63

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.
