I was reprogramming the Wakespeed WS500 Pro alternator regulator yesterday, to take advantage of the whitespace feature—more on that in a step by step guide by Eric Klem, all written, edited, and coming late this month.
While I was at it, I was able to displaying the charging voltage and mode the regulator is in (bulk, accept, or float) on our on-deck plotter, as shown in the photo above.
Sure, given that Al Thomason at Wakespeed kindly arranged for us to get a replacement Pro regulator with Bluetooth for evaluation, I could see the same information on the app (and a whole lot more) but that would require me screwing with my phone, which I think is distracting when underway and therefore bad practice.
And of course those with the older WS500s, (without Bluetooth) will find this doubly useful.
