he said the car wouldnt start, but would with a jump.. he thought it was a battery or wiring problem,,, so i went over there with my van, and after charging it awhile with jumper cables, it started to crank. after a bit more charging, it turned over and we drove it home. while driving, the car had no electrical- no lights, blinkers, radio, etc.
got home, parked in driveway and turned it off.. i had the battery tested and charged, tested good.
tried to start,- the car has electrical, lights, blinkers, clock ticks, etc at key pos II.. but when turning the key all the way, no cranking, nothing.
tried a brand new battery fro-m my other 240D, same thing.
hooked it up to my van with jumpers, same deal, accessories work, but no cranking...
i checked fuses all are good.
any ideas what might be happening? why it started the first time with a jump but had no accessories, now i have them, but no cranking..!!
