I charged up the battery, only got 7Ah into it which is a bit worrying, considering the voltage before I charged it was 13.18V which should be around 50% capacity.
I removed the aux belt, and started the car with battery only. The idling current draw was 25A. I got my mum to keep the revs just above 2000rpm and the current was still steady at 25A, measured with a good clamp meter at the negative cable.
I hope its not going to draw more when actually moving?
I was expecting it to draw more as rpm increases but this doesn't seem to be the case.
Its a 20 minute, 5.6 mile drive to the mechanic. Looks like I could make it.
Even if the capacity is only 14Ah, that should give me just over 30mins in theory.
Tomorrow is the day of reckoning
