Car's a 1987 998 and over the last couple of months has developed a few problems starting. I've had to put a recon starter motor on as the missus burnt the starter clutch out, this improved things somewhat. Unfortunately now, every once in a while when I crank her over she turns really slowly as if the battery is flat, which it is not. I've checked the alternator which is throwing out just under 14 volts (13.8 to be precise), checked all the connections etc that are all tight so this is leading me to thing I've got some wiring breaking down somewhere. Any ideas where to start looking ?
TIA Jim
