IN CAR CONNECT TO BATTERY AND NOT HAVE CAR BATTERY CABLE CONNECTED, HE CHARGER HAS BRIAN THAT WE ALL KNOW IS TINY AND LAME. OR SMARTER THAN THE AVERAGE BEAR. IF THE BATTERY HAS 1 WEAK CELL IT , MAY SHUT OFF. THIS IS TO PREVENT BATTERY EXPLOSIONS. EVEN CARS NEW, ALTERNATORS DO THIS TRICK./ USE A VOLT METER, AND CHECK BATTERY VOLTAGE FIRST, IF AT 10V A CELL IS OPEN OR SHORTED,AND BOTH ARE BAD NEWS,. EOL OF BATTERY.

There is a 1335 Farm and Ranch charger that is 200 amp. The 1235 does not say it is Farm and Ranch on the face, and is a 100 amp charger although automatic. It looks different from the 1335. I don't find a manual or the charger currently for sale on the Shumacher page but I do find you can download a manual for the SC1308 there and it physically looks like the fro1235, has the same interface controls, and is a 100 amp charger like the fro1235. I suspect the directions are the same for the interface. I have read consuer messages saying these manuals are confusing. If such is the case, you can try the customer service contact at the website. That said, these are supposed to be automatic and to not work if connectd to the wrong terminals by design. https://www.schumacherelectric.com/products/100a-6v-12v-fully-automatic-battery-charger-engine-starter/#manualTutorials

Anybody know how to take one of these apart to replace battery? I removed all visible screws,but apparently there are some hidden ones

I think it can be repaired. May be some capacitor or zener diode.  

I would like to see a wire diagram of my battery charger Schumacher model #se-5212a-CA

When the amp meter reads 0, then it is no longer drawing amps and is fully charged.

i hope this was helpful,

I have the same one. The black wire from teh ac cord has a white connector that goes on the switch but there are 4 choices. I need a diagram as well.

the wire at the clamps might have came off,there is a thermal fuse inside the charger also, get one at the auto parts store .bring the old one with you. OR some of the newer chargers are fussy that the battery must have some power to get the charger to turn on.. i use jumper cables to get my charger started..
DID I HELP ? VOTE . THANKS J

Go to www.batterychargers.com. Then go to search bar on the site, type in your model number and search. It will work for you so you can download the manual in PDF. I just did it so I know it works. Hope this helps you.

I believe you'll find all you need to know in the owner's manual which you can find here: http://www.batterychargers.com/Documents/00-99-000821.pdf There is no schematic other than the operating instruction on p9. Connect red to red, black to black (usually earth).
