Overcharging Alternator Symptoms

Overcharging Alternator Symptoms

High voltage reading  Overcharging Alternator Symptoms

If your automobile’s alternator has high voltage readings, some signs may be visible. Below are some common signs that you may look for:

Electrical wiring heat- The very high voltage of the alternator can cause the vehicle’s electrical wiring to heat up. This can cause dust and carbon to build up on the strings, which can increase the likelihood of fraying.

Left and Right Turn Lamp Red or Green- Due to the high voltage of the alternator, your vehicle’s left and right turn lamp may come on and show an unusual color (red or green).

Possibility of an electrical system malfunction- Due to excessive voltage, your vehicle’s electrical system (such as reverse lights, indicators, and wipers or sound system) may get damaged. The existence of these mechanisms can lead to changes or destroy them completely.

Risk of Electrical Undesirable or Battery Damage- When your automobile’s alternator has high voltage, it can damage your vehicle’s electrical undesired or battery. As a result, the life of the battery may be reduced and the initial charging capability of the vehicle may be affected.
