Schumacher Electric Automatic Jump Starter, Battery Charger and Maintainer, 4 in 1, SC1361, 50 A, 12 V

It does what it claims to do. Here's the "buts". My experience with Schumacher over the past 50+years has been positive, but several years ago my analog charger finally hit the blitz. Hence I was resigned to purchase this model. Generally I despise things that market automation over functionality. My career revolved around fixing these devises. This charger works but doesn't tell me what it is doing until it stops trying to do what I asked of it. It doesn't tell what the battery voltage was before it decided not to charge and giving that fault light. My fix: applying a temporary shunt voltage so the charger can be tricked into activating the power relay. The absence of an ammeter is frustrating to assess the battery condition during the charge operation. An AC ON/OFF power switch would be nice. And too an outlet for connecting the charge cables. My plans: add an ON/OFF (I/O) switch and an ammeter (100A) to the charger and an "Anderson" type connector for the charge cables. I'll see how it goes. My unit is well pass any warranty. But these things are what i look for when purchasing a charger.

Have used to charge and maintain car and hybrid scooter / motorcycle batteries for a couple of years nonstop. Has worked flawlessly.

Bought this because it's supposed to boost batteries and start engines when the battery is dead. Just sits there with the ENGINE START and CHARGING lights lit, but does nothing. Put a clamp-on ammeter on the leads to check and it's zero amps! (yes on DC). Trash. Buy any other brand but this one.

I bought it about a year ago, it worked nice.. but suddenly it stopped working after being stored for months .. it doesn't charge anything anymore, just the lights get on but nothing happens.. 😭 I'm from mexico, could you provide me the service center info in my country?
