Hi guys, new here.

I received two of these from a local that didn’t want to try to install them.

I tried the 2-wire route with getting power and ground from the driver to the board.

It’s not lighting up… I’m wondering if there is a way to troubleshoot if I messed up the board itself.

On a multi meter, I am getting current when I check the leads going from the driver to the aux board.

Once all connected, the fw3a works as it should, but the Aux board does not light up. Afraid I might have fried them it somehow.

These are 2.1 boards.
