    Hi

    Does anybody know the best way to test a low voltage regulator, the full details on mine are as follows

    LM2931

    This is fitted on a pcb for a range rover electric windows and this board is a known failure.

    Simply measure the output voltage on the output leg. The voltmeter should indicate something around 5V. Also measure the input voltage (must be larger then 5.6V).
