Can I get a schematic diagram for a Sears DieHard Battery Charger/Engine Starter model 200.71223?

I have the listed battery charger and it is not working properly. The manual trouble shooting guide does not help, but only recommends returning it for repair. It is out of warranty, and if I can't fix it I will replace it. There is proper voltage to the output stage, but it appears the SCR gates are not being fired. Without further information and not wanting to disassemble the unit, I need a schematic to take the troubleshooting further.

Thank you for your question.

I can understand wanting to fix the battery charger yourself.

I am sorry but the manufacture, Schumacher, do not provide anything beyond a wiring diagram and does not provide component lever schematics for repair by the owner.

I believe that the problem is in the SCR module and when I looked it up, it shows it not to be available anymore, along with a couple other parts.

So I suggest that you replace this battery charger with a new one.

Thank you for using Manage My Life.
