Check each splice very carefully. If the tape is loose, you should remove it. Check the
splice and retape it if it is good. If the splice is loose, cut it out and resplice the line. Be sure you do
both conductors so the wire retains its original look. You don't want one conductor shorter than the
If there is a spot where there are several splices within a short distance, two or three
splices within 10 to 15 feet, cut out that section and make one new splice. The more splices you have in
the wire, the greater the possibility of having trouble the next time you use it.
After each splice and at the end of the wire, test the line for opens, shorts and high
resistances. Use the TA-312/PT you have at your location for the test. If you cannot ring through or the
crank turns hard and jerky, you have a problem and you must rewind the wire and recheck it. The line
must ring through and you should be able to talk on it with no problems.
If the wire passes the physical and electrical tests and repairs/splices are good, keep in mind that
the number of splices will determine if the wire is usable. If the line has no more than four splices per
conductor per 1/2 mile, it can be considered fully serviceable and you can tag the line and identify it as
Class A. Put the date on the tag and initial it.
If the wire has more than four splices per conductor per 1/2 mile, it is considered serviceable but
should be tagged Class B. This wire should be used only in the zone of interior or for training purposes.
After the wire has been allowed to dry, it should be placed with other wire of the same class and
stored for use at a later date.
If the line was installed using an MX-306A/G do not try to refill it. Turn it in to supply for
return and refill. The wire that came from the MX-306A/G can be recovered and serviced the same way
as the wire from an RL-159/U.
If you had access to the equipment and had recovered a wire line, service the wire you recovered.
