Subaru Legacy/Outback

1. Remember that violations of functioning of system of a charge are far not necessarily connected with failures of the generator. First of all always make the following elementary checks:

a) Check a state and effort of a tension of a driving belt of the generator (see the Head Routine maintenance). In case of need make replacement;
b) Check reliability of a tightening of fixing bolts of the generator;
c) Check a condition of an electrical wiring and electric connections of the generator;
d) At the corresponding complete set check a condition of the fusible insert established between the traction relay of a starter and the generator, or a condition of big main safety locks in a motive compartment. In case of identification of the beaten-out elements, establish and eliminate the reason of the overloads taking place, then replace defective components;
e) Check a condition of all safety locks included in an electric chain of system of a charge. Location of safety locks and fusible inserts can vary depending on model and year of release of the car;
f) Start the engine and estimate intensity of the noise background published by the generator;
g) Check electrolyte density in banks of the battery, in case of need make recharge of the last;
h) Make sure of completeness of a charge of the battery, - one faulty can can be the reason of a recharge of the battery;
i) Disconnect from the battery both wires (at first negative). Estimate a condition of wires of the battery in places of their connection to polar plugs of the last. Check reliability of fastening of terminal clips. Having carefully smoothed out contact plugs, connect the battery.
2. By means of the voltmeter measure tension which is given out by the battery at the killed engine, - the result of measurement has to make about 12 Century.
3. Start the engine and repeat check: this time indications have to make 14.1 ÷ 14.8 Century.
4. Include head headlights, - at regularly functioning system of a charge tension has to fall at first, then be restored to former level.
5. If the size of the measured tension considerably exceeds nominal rate, replace tension regulator.
6. At excessively low indications make checks of the regulator of tension and the generator (see below).
