My 98SLK230 would not start after a short drive. Not a click or anything. Had been starting and driving great until then. Had AAA come and jump started fine. Drove home and top would not go up, even with engine running. Would not restart, again not even a click. Put on my trickle charger for five days and no affect. Jump started it again, and with engine running top would not activate, and radio would go off when I was pushing roof switch. With motor off power door locks work but headlights do not come on. Battery was new last fall, and measures 38 volts while running and 35 volts when motor is off. Fuses look ok. I'm at a loss, and hope someone in this forum can help.
