I have a margalla 95. I haven't driven it for quite some days and I couldn't make it start when I tried yesterday. So I took out its battery and charged it with UPS.
When I put it in the car in the morning (UPS was showing battery full when I un plugged), it couldn't even turn on the switch, i.e. no response at all. Could it be that I connected wrong terminals (connected red with positive and black with negative, that is standard practice) or there might be some other reason.
