Converting a 005A with a Digital Controller

[peapvp]

@peapvp I think something that will leave many curses uttered is the fuel pump comtrol (mainly because it just left me cursing). You have the fuel pump relay being driven by the mebay only, When you change filters (or drain the day tank) the pumps need to be forced on to refill and prime. might me useful to add a easy means of forcing the pumps on.

A pushbutton switch perhaps in parallel with the MeBay output.
That’s why we used KUP relays. I didn’t trust the MeBay indicated switching current of their internal relays.

I'd use something maintained. A full refill and prime takes longer than I'd want to stand there and hold a button.

@Scoobyshep
Larry and myself programmed the MeBay controller with a 15 second delay before crank.

We tested it first with a 60 second delay and then a 30 second delay and settled for 15 seconds as this would fill the daytank to about half capacity from complete empty.

We used parameter Group 3 #33 fuel output delay

meaning delay of crank output activation and fuel pump activation
