Almost new model sc-1281, charging a battery ina vehicle. I plugged th charger in, connected the red clamp to the plus anode and when I go to clamp on to the negative terminal, it welds the clamp to the terminal, If I would let it.

If your Schumacher Electric SC1281 charger causes a dead short when connecting to a vehicle battery, check the connections and settings. If the issue continues, replace the battery.

Hi. I have a Shumacher SC 1281 that has been used once. I bought it about 1-1.5 yrs ago. When I plugged the charger in today, nothing lights up. No stop/start action, no select battery action, no level of charge action. Did I buy a dud?

If the Schumacher Electric SC1281 charger does not light up or show any signs of functioning after being used once, possible issues include:
- The battery voltage is too low (below 10V for 12V batteries or 5V for 6V batteries), which may prevent the charger from starting. - The Bad Battery LED may indicate a defective battery or one with a load attached; remove any loads and try again. - The START/STOP button may not have been pressed; pressing it can begin charging. - Charging may begin after 30 seconds even if the LED does not light up immediately.
If none of these steps resolve the issue, the charger or battery may be defective.
