It appears to have resolved the issue with my Automatic Transfer Switch (ATS) where the signal to the generator was indicating the main supply power had failed incorrectly. However, this has been an intermittent issue, so not sure it's completely resolve, however an external (to the board) relay now does audibly transfer when power is on. That didn't happen to my recollection prior to the replacement board.
Also, this was a great value (and although the box indicated 'refurbrished' but I don't remember the eBay indicating it had been refurbished, only that it was an open box. I likely would still have purchased it as I was unsure the original board was at fault and it was a lot cheaper than getting a Briggs and Stratton certified tech to figure it out.
