I have a Smart Forfour, the battery has been flat, changed the battery and absolutely no electricity whatsoever (no clock on dashboard etc), think new one was duff - but when I put the old one back in although the clock shows etc I can't jumpstart it with leads - any ideas?

Use a DVOM check voltage at BATT then from BATT POS to engine block
