Increase the charge rate of your alternator by around 0.5 volts on your Toyota by simply removing the alternator signal fuse (ALT-S) and replace it with the booster diode.
Increasing the voltage by 0.5 volts helps maintain your cranking as well as auxiliary batteries and paired with our LC70 FreezeBrain AC Amplifier constant idle up feature really helps with heavy charge loads on vehicles equipped with accessories.
Simple installation and comes with full instructions.
Purchase a diode with a FreezeBrain and only pay $30 for the diode!
