Schumacher Battery Charger Button Fix (Rate Selector) Heavy Duty 

I've been looking everywhere for any diagram info for the schumacher "farm and ranch" battery charger. It's basically the same thing as that. The problem I'm having is that it keeps saying it's not hooked up to a battery. So I tried to take it apart and see if there were any loose connections and I didn't see any. Anyone have any ideas?

my lights came on just no clamp power so i got to thinking just before i tossed it i though ima cut the clamps off and touch the wires and sure enough there was my problem ... heres the kicker .. a half inch behind the the clamp wire connectors it was cut even i only noticed when i was removing the old wire from the clamps as i pulled the wire came out of the insilation a half inch but was a clean cut not normal for breaking strands it was like this on ground and positive .. i beleive it was manufactured to faile... jokes on them i fixed it

I have the same unit but I'm not getting no power 2 the unit none of the light would come on on the panel could you tell me what the do at that point

Can you send me schematic diagram pelease?

On same exact charger the button makes the light come on & selects properly but light flashes & doesnt charger or jump start at all any ideas? Also only 1 light illuminates
