I have a Lester 48 volt 17 amp battery charger. it has an electronic controller/timer encapsulated in epoxy and has obviously gone bad. It also has 2 SCR's that are shorted. I called to price the controller and it's $200 so it's not worth that to me.
So, I plan to convert it to just a straight charger eliminating the SCR's and the controller/timer module similar to another model they have (schematic shown below) and just use a plug in timer to control the charge time.
My question is, what is the separate transformer coil and capacitor for ?
Thanks,
Steve
