TROUBLESHOOTING

Do not attempt to repair the 

128

yourself. There are no user serviceable

parts inside, and special tools and techniques are required for reassembly
to ensure the waterproof integrity of the housing. Repairs should be
performed only by authorized Teleflex technicians.

Many requests for repair received by Teleflex involve units that do not
actually need repair. These units are returned “no problem found.” If you
have a problem with your 

128

, use the following troubleshooting guide

before calling Customer Support or sending your unit in for repair. The

128

contains several tools that can aid in determining if there is a

problem and how to isolate and repair the problem in many cases.

1. Nothing happens when I turn the unit on.

Check the power cable connection at both ends. Be sure the cable is
connected correctly to a reliable power source—red lead to positive, black
lead to negative or ground. Ensure the power available at the mount is
between 10 and 20 VDC. If the unit is wired through a fuse panel,
ensure the panel is powered. Often accessory fuse panels are controlled
by a separate switch or the ignition switch. Also, often a fuse can appear
to be good when in fact is not. Check the fuse with a tester or replace it
with a fuse known to be good.

Check the power connection to the 

128

. It is possible to force the power

cable connector into the cable holder incorrectly. If the connector is
reversed, the unit will not work. Examine the contacts on the back of the
unit to ensure there is no corrosion. 

Ensure the cables are properly installed into the collector plug and the
collector plug is properly seated into the 

128

.
