Mobiletron have announced the launch of their new COM02 Voltage regulator tester that has been developed to reduce costs for BSS and LIN regulator testing. The portable handheld tester with an intuitive interface tests both RVC and COM regulators.

This latest addition to Mobiletron’s rotating electrical range allows the user to assess whether the voltage regulator is in full working order, while eliminating the need to remove the alternator from the vehicle. A vehicle’s voltage regulator controls power distribution from the alternator to the battery and the tester is an essential tool as it will ensure that any faults are easily identified and can be resolved as quickly as possible.

The COM02 Tester is designed for ease of use and comes with a universal testing cable. The tester works with both BSS and LIN protocols up to LIN 2.0 and also works with popular voltage regulators from Bosch, Denso, Mitsubishi and Valeo.

Several pre-set duty cycles for RVC regulators can be selected to test the varying output voltage. For COM regulators there are built in voltage pre-sets used to check the communication of the regulator is functioning correctly. The tester will provide error codes for both RVC and COM regulators to give accurate test results. The COM02 can also be used in conjunction with the VRT-10 or ALT-98 tester. The tester will also read and display COM Regulator ID codes to avoid incorrect installation.

The unit also automatically detect the regulator’s protocol and ID code. This is paramount as when the protocol and/or ID do not match perfectly the regulator will not function as intended.

Mobiletron’s technical engineer Daniel Jackson says, “Mobiletron saw a gap in the market for a handheld regulator tester. The key feature being the tester can be used on the vehicle with minimal disassembly required. With additional features such as the varying output voltage, the regulators can be tested across their whole voltage charge range. Importantly the tester is future-proofed with the ability to update it using a USB drive.”
