plastic rosin mixtures, shall be used as a flux in the assembly of the
electrical wiring.
3.19 Power line connector cable. A rubber jacketed flexible cable 10 feet
2 inches in overall length and using 3 stranded conductors capable of
adequately carrying the current required by the test set shall be provided.
The cable shall be wired in accordance with MIL-STD-1653 for 400 Hz, single
phase, 115 volts.
One of the conductors shall be used for grounding the test
set. The cable shall be equipped on one end with an MS3106A-20-4S connector
plug which shall mate with an MS3102R-2O-4P receptacle mounted in a suitable
location on the control panel. The other end shall terminate with an
MS3507A-20-4P connector plug. The cable shall be stowed in the stowage
compartment.
3.20 Adapter cables.
Three adapter cables as shown in Figure 4 shall be
furnished with the test set for facilitating the connection of aircraft
These adapters shall
tachometer generators and indicators undergoing tests.
be stowed in the stowage compartment. An additional adapter having the same
desgin characteristics of adapter B with the exception that one end shall be
equipped with an AN3057-6 adapter and an MS3106E-14S-5S connector shall be
provided.
An additional adapter shall be provided which shall have the same
Two tee adapters shall also be provided so that the digital indicator section
of the test set may be connected in parallel with indicators installed in
aircraft. One of these tee adapters shall be suitable for use with tachometer
indicators designed to mate with an MS3106-1OSL-3S connector plug; the other
tee adapter shall be suitable for use with tachometer indicators designed to

with a chemical film in accordance with MIL-C-5541. Where the primary purpose
of the treatment is to affort a suitable paint base, chemical treatments in
accordance with MIL-C-5541 may be used in lieu of anodizing. Castings
containing nonaluminum alloy integral inserts may be treated with a chemical
film in accordance with MIL-C-5541 in lieu of anodizing, When abrasion
resistance is a factor, chemical films in accordance with MIL-C-5541 shall not
be used in lieu of anodizing.
