Honda Accord

First of all always make the following elementary checks:

a) Check a condition of wires of the battery in places of their connection them to polar plugs of the last. Check reliability of fastening of terminal clips;
b) Check a condition of the battery (see the Section Check of a State and Replacement of the Battery). In case of need make recharge of the last, or replace it new;
c) Check a condition of an electrical wiring and electric connections of the generator and regulator of tension;
d) Check a state and effort of a tension of a driving belt of the generator (see the Head Nastroyki and routine maintenance). In case of need make replacement;
e) Check reliability of a tightening of bolts of fastening of the generator;
f) Start the engine and estimate intensity of the noise background published by the generator;
g) At the corresponding complete set, check a condition of fusible inserts in the assembly block in a motive compartment of the car (see the Head Onboard electric equipment). If any of inserts failed, make investigation and elimination of the reasons of an overload;
h) Check serviceability of functioning of a control lamp of a charge in an instrument guard of the engine. At the included ignition and the idle engine the lamp has to burn. Otherwise disconnect the 4-contact socket from the back party of the generator and ground the plug No. 3 (V6 engines) or No. 4 (4-cylinder engines). If the lamp does not join and now, check a condition of a safety lock No. 6 on 15 A, and also filaments actually of a lamp. Make necessary replacements;
i) Check contents of the block of memory of the onboard processor for existence of the codes of malfunctions of system of monitoring electric loadings (ELD) which are written down in it (see the Head Engine management).
2. Having switched off ignition, by means of the voltmeter measure tension which is given out by the battery on the back party of the generator at the disconnected consumers of the electric power (the heater fan, the radio receiver, the lighter, the cooling system fan, etc., etc.). The result of measurement has to make about 12.5 In, or is slightly higher if the engine worked within the last hour.

3. Start the engine and repeat measurement. With a frequency of rotation of a cranked shaft of 1500 rpm tension has to make 13.8 ÷ 14.8 Century.

4. Turn on a driving beam of head headlights, start the K/V fan on the maximum high-speed mode, include heating of back glass and the radio receiver. At normal functioning of system of a charge tension has to fall for a short time, then again to come to a normal operating level about 13.5 Century. If there is a lowering of tension below than to 13 V, therefore, serviceability of functioning of system is broken.
5. Dump engine turns to single, - tension of a charge should not fall below values in 13 V. squeezing of a foot brake should not give to further undervoltage (lower than 13 V).

Some low-power generators can allow short-term lowering of the developed tension below value in 13 V, however then it has to be restored quickly.

6. Disconnect everything consumers of the electric power, lift engine turns to 1600 in a minute and again consider the indication of the voltmeter. Now tension should not rise above value of 15 V (the insignificant deviations in inverse proportion connected with ambient temperature are admissible).
7. If the voltmeter registers excellent from stipulated values, it is necessary to replace assembly of the generator with tension regulator.
