(2) Check for alternator output current
Turn headlight high-beam on (to put a load on the alternator) and take the output current reading while maintaining a
speed of 2000 rpm. If the current reading is greater than the standard, the alternator is in good condition.
7) Trouble Shooting.
(1) FAILURE IN CHARGING SYSTEM
The following are considered failures in the charging system.
1. Excessive battery discharging
: Starter does not run (or runs slow) and headlamps are dim.
2. Overcharging : Battery electrolyte diminishes sooner than normal.
3. Charge lamp failure : Does not light, is not turned off, or is lit dimly during vehicle operation.
4. Noise : Drumming, hissing, heavy groaning, or radio noises.
The cause of the noise should be narrowed down to the battery, wiring, alternator, regulator, or vehicle running condition.
(2) PRELIMINARY CHECK
Before starting this check, the following should be checked.
1. Confirmation of faulty condition.
2. Fan belt check: Check it for slippage due to cuts, dislocation, and slack. Belt tension is to be shown in Engine
Assembly.
3. Wiring placement: Check if the wiring for the alternator and battery is properly placed.
4. Contact of connectors.
5. Installation of alternator: Check for proper belt alignment and securing of installation bolt.
6. Battery check: The battery sometimes discharges due to current leakage through corrosion and stains in the vicinity of
its terminals. Check for electrolyte shortage, deformation of electropole plates, and changes in its color to white. Lost
electrolyte should be replaced with distilled water.
