Schumacher MC-1 motorcycle battery charger

My 1 amp 12 volt charger quit working. So removed the cover and found one of the two diodes for the dc circuit had split into. Can't find a schematic or wiring diagram to give detail on the diode and it's so small hard to read number on it. I was wondering if as a 1 amp charger would it take a 1 amp rated diode or does it need to be larger by some degree. I know quite often it seems things like this in these kinds of devices need to be overrated. Any help would be appreciated.

I would go for a two amp or larger. You don't want a 1 amp diode running at 1 amp. There probably won't a price difference.

1N5400 is a good general purpose 50v 3A diode. (.35 each at mouser)
I use bags of 6A05 diodes. 50v 6A diodes. (.30 each at Mouser) (.15 each in bulk)

The hardest part will be where to find them at true cost. Places like DigiKey and Mouser have no minimum order or dollar amount but you will pay shipping. I see them on amazon but $2-4 a piece is unrealistic.

Look around for a local electronic parts store.
