hi - new member; glad i found you. i'm an intermediate or maybe advanced beginner in electronics, but have done my own repairs, builds for electro-mechanical devices for many years. recently, not 1, not two, but three of the various battery chargers that i own for lead-acids have failed me. the one i'm trying to repair right now is a schumacher se1275a. can anyone help me with diagnostic/ troubleshooting procedures for this particular model. a thank you to sgt wookie for the link to century tool parts for schumacher parts (listed in a different thread for repair for a different schumacher model). i found their parts list for my model through that link, anfd it looks like i can get whatever i need through them; i just need to know what i need first. it looks like diodes are a very typical culprit from other posts and other research i have done. to boot my current dmm has chosen to crap out at the same time - anyone recommend a new one for the occasional but serious user for under a hundred $? i had a radio shack zzzz for about the last ten years, served me well for about the last 8-10 years; looking for one with about the same functionality and price point. thanks a million!
