~1min read

When connecting the battery cables on vehicles equipped with an alternator, observe the following special precautions:

a) When connecting the battery cable to the alternator, never reverse the polarity;
b) Before performing electric arc welding during body repair, disconnect the wiring from the alternator and battery terminals;
c) Never start the engine while a battery charger is connected to the battery;
d) Always disconnect both cables from the battery before charging it from an external power source (negative cable first);
e) Keep hands, hair, and loose clothing away from the rotating alternator drive belt during checks performed with the engine running;
f) Since the alternator is connected directly to the battery, an overload or short circuit can cause the wiring to ignite and result in a fire;
g) Before steam cleaning the engine compartment, wrap the alternator in a plastic bag and secure it firmly with rubber bands.
