I had a problem with my starter motor clicking when engaging and disengaging, i had it replaced and that fixed the starting problem. Later that day my battery warning light began to flicker but when i accellerated it went away.
I checked the voltage on my battery whith the engine running and it was only showing 12.05 volts, the following day i checked it and it was showing 11.8 volts. So the alternator is not charging the battery what so ever. Could this be down to the starter motor being slightly more powerful then the original Ford Starter Motor.
