When the red battery discharge indicator light is on in the instrument cluster, when the engine is running, it means that the current is not supplied from the generator to the on-board network
Operating a car with a lit battery discharge warning light is unacceptable, as sometimes the cause of the light may be a short circuit in the wiring, leading to a fire in the engine compartment of the car
We need to stop the car, turn off the engine and find out the reason for the light on the lamp
If the cause of the malfunction is not a short circuit and the battery was fully charged, you can drive to the garage without a generator, but it is better to fix the problem on the spot
Electrical check
Check the condition of the alternator drive belt.
If the belt breaks, then replace the belt
If the belt is intact, we check and, if necessary, replace the automatic belt tensioner for the auxiliary drive belt
We also check the wires connected to the positive terminal of the battery
Check the wire going to the starter and generator.
Wires can be broken, broken inside the insulation, or with oxidized and unreliable contacts
Repair the problem and start the engine
If charging appears, you can continue moving
If there is no charging, check if the ALT-S fuse (7.5 A) is blown, shown in the figure by an arrow, in the mounting block under the hood
If, after the measures taken, the discharge lamp continues to burn when the engine is running, then the possible cause of the malfunction is in the generator itself
To reduce current consumption when driving a car with a faulty generator, you need to turn off unnecessary devices, a heater fan, radio, etc.
