Charging System Safety - 1984 22L SOHC Turbo VIN E - Service Precautions
Charging System: Customer Safety Information
1.
Be certain that battery polarity is correct when servicing units. Reversed battery polarity will damage rectifiers and regulators.
2.
If booster battery is used for starting, be sure to use correct polarity in hook up.
3.
When a fast charger is used to charge a vehicle battery, the vehicle battery cables should be disconnected unless the fast charger is equipped with a
special Alternator Protector, in which case the vehicle battery cables need not be disconnected. Also the fast charger should never be used to start
a vehicle as damage to rectifiers will result.
4.
Lead connections to the grounded rectifiers (negative) should never be soldered as the excessive heat may damage the rectifiers.
5.
Unless the system includes a load relay or field relay, grounding the alternator output terminal will damage the alternator and/or circuits. This is
true even when the system is not in operation since no circuit breaker is used and the battery is applied to the alternator output terminal at all times.
The field or load relay acts as a circuit breaker in that it is controlled by the ignition switch.
6.
When adjusting the voltage regulator, do not short the adjusting tool to the regulator base as the regulator may be damaged. The tool should be
insulated by taping or by installing a plastic sleeve.
7.
Before making any "on vehicle" tests of the alternator or regulator, the battery should be checked and the circuit inspected for faulty wiring or
insulation, loose or corroded connections and poor ground circuits.
8.
Check alternator belt tension to be sure the belt is tight enough to prevent slipping under load.
9.
The ignition switch should be off and the battery ground cable disconnected before making any test connections to prevent damage to the system.
10.
The vehicle battery must be fully charged or a fully charged battery may be installed for test purposes.
