(2) Precautions
The following precautions are to be observed when testing or servicing the electrical system.
(a) Disconnect battery before connecting or disconnecting test instruments, except voltmeter, or
before removing or replacing any unit or wiring. Accidental grounding or shorting at
regulator, alternator, ammeter or accessories, will cause severe damage to units and/or
wiring.
(b) Do not operate alternator on an open circuit with the rotor winding energized.
(c) Do not attempt to polarize alternator. No polarization is required. Any polarization attempt
may result in damage to alternator, regulator or circuits.
(d) Grounding alternator output terminal may damage alternator and/or circuit and components.
(e) Do not attempt to polarize alternator. No polarization is required. Any polarization attempt
may result in damage to alternator, regulator or circuits.
(f) If booster battery or fast charger is used, its polarity must be connected correctly to prevent
damage to electrical system components.
— NOTE —
If a solderless terminal on an aluminum cable is loose, corrod-
ed or otherwise unsatisfactory, it is recommended that the
complete cable assembly be replaced instead of replacing or
repairing the solderless terminal. Should replacement of the
complete assembly not be practical, it is permissible to replace
the aluminum cable assembly with a copper cable assembly
which is two sizes smaller (EX: AL-1 aluminum cable assembly
is replaced with an AN-3 copper cable assembly). The new
cable should be installed in accordance with AC-43-13-2A.
