Anyone ever checked what the charging voltage output is from their alternator ? I've got the usual flat battery problem again not having used the car for a week. It's the original Ford 43Ah battery and this morning was 11,7V.... hence no start.
So I'm currently letting the engine idle over for a couple of hours to charge it, voltage while idling is now 14.1V (from the alternator?)... this voltage does not change if engine revs increase, so a blast down the motorway won't make any difference to charging.
I'm thinking of changing the battery for one supplying 60Ah, Kwifit seem to have them in, but no use doing that if the alternator output isn't right.... hence my question. Cheers.
