Low voltage readings 535i M30

[Zackb911]

Hey guys I just replaced my battery but I am suspect of my alternator or voltage regulator. I checked the voltage at the battery with my digital multimeter while running and get 13.17-13.18, when I turn on the lights it dips and holds steady at ~13.02. This seems fairly low to me but seems like the alternator is working should I replace my voltage regulator? I am placing an order with BMA today so I need to know:)

Thanks!

Hey Bill, what do you think of Mark Calabrese's voltage regulator upgrade? Adds a series diode between the regulator and ground to bump output by the 0.5V diode drop.
