Hey all, after some help/advice
My cars always had crap voltage, about 12.7 charging 13.2 is the best i have ever seen.
Its just had the new engine in, with, what looks like, a pretty new alternator, and still, charging at 12.7v revving, 12 idling.
Thats clearly no good for an 044 feeding 500 ponies.
I have uprated the alternator main wire to the battery with 8awg, and the engine bay earths are uprated, its got an Optima Yellow top 75ah battery too.
My reading is taken from the fuel pump terminals.
Obviously i want 14.4 or as close as i can get there, anyone got any idea's why its so crap?
Its not going to be safe to drive hard as it is, and i am running out of idea's?
