REGULATOR & CHARGING GENERATOR CONTROLS
When mounting a new battery or in the case of a defective battery, check the battery-related electrical equipment of the vehicle.
The most common mistake that may be made in a vehicle is overcharging or undercharging. Check whether the output voltage of the alternator with a standart battery and at full throttle is in the range of 13.8 – 14.4 volts for proper operation of the electric systems for the Ca-Ca batteries.
LEAK CURRENT CONTROL
Attach a clamp meter to the cable that comes out from the (-) terminal of the battery. The value of the currency flowing through the cable is the constant consumption (leak current) value of the vehicle.
Another method is to connect a digital voltmeter between the ground cable and the battery. Then, all electric consumers are turned off. If there is no leakage, the device will not show any value. In the case of leakage, the device may show a value like 1-2 V.
STARTER MOTOR CONTROL
Check and note the Volt value showed by the device’s needle when the vehicle is started.
Turn off the engine.
Load the battery by means of the voltmeter (that is, turn the starter button for 5 to 10 seconds). Check and note the Volt value showed by the device’s needle.
Compare it with the previous voltage value. The starter motor is normal if there is no significant difference between two voltage values. Otherwise, it means that the starter motor is defective and it must be replaced immediately !!!
