Schott Battery Charger Help

Hi all,
My hobby and interest lies with electric vehicles. I have designed and built them since 1993. i feel it’s an honor to be part of this forum community. Now, on to my delema. I have a defective Schott 72 volt 10 amp battery charger; I would like to repair it. Does anyone have schematics or some helpful advice?

The Schott charger is considered obsolete. My recommended replacements are the Zivan NG1 found on later GEMs, or the Quick Charge SCO7210 that is widely used as an aftermarket replacement. Both are good quality and have good product support.
