If your Volvo has been fitted with aftermarket lighting equipment, a high powered stereo or other electrical accessories, your charging system may not be up to the task. We now offer an adjustable voltage regulator that will allow you to preset the operating voltage of the charging system and keep the system voltage stable. This can help in two ways; you’re able to adjust the voltage higher than normal to help your lights stay bright while using heater, wipers, etc., and you can also prevent voltage spikes after startup (which can lead to blown bulbs).
Directly compatible with all B18 and B20 applications that have been fitted with or converted to Bosch alternators.
