Note: Only some variants of the 2019-2020 Tundra can be fitted with a voltage booster, please check the main fuse box in the engine bay for a fuse that is designated "ALT-S", if your vehicle is fitted with that fuse then you can fit the voltage booster.

PTC electronic fuse version.

The HKB Electronics Alternator Voltage Booster was the first device of its available and the only device on the market that has been purpose designed for alternator voltage boosting.

The MK2 version of the Alternator Voltage Booster from HKB Electronics and differs from all other diode booster units in that it is the only device of its type available that incorporates an auto resetting PTC fuse.

The PTC device (electronic fuse) incorporated in the MK3 offers far better circuit protection than both the OEM fuse it replaces and all other types of voltage boosters. Should an electrical fault develop in the vehicles wiring other types of booster diodes will be destroyed and need to be replaced, this is not the case with the MK2 unit, in the event of an electrical fault occurring, the PTC device in the MK2 detects the excessive current flow and turns off preventing damage to the booster unit, the vehicles wiring, and alternator. Once the electrical fault has been removed the PTC device automatically resets and the booster unit will resume normal operation.

The MK2 Alternator Voltage Booster is proudly designed and manufactured in Australia using only the highest quality locally sourced components and comes with a 3 year warranty covering both parts and workmanship. Here's your chance to support a great Aussie made product!
