Ok, I have the readings...
Just to recap, my battery light is always on and so is the abs trifecta.
My battery died on the drive the other day but I think it was because I had the doors open for 4 hours whilst changing the carrier. It's since been on a trickle charger.
Battery was dead 11.2v
Charged up to 13.16v
After first start 12.53v
After 1 hr with battery disconnected from car 12.6v
Started car after 1 hr, idled at 13.8v
Revved to 1500 and got 13.92v
car is now idling between 13.8 and 13.85v

I don't see what is wrong? These numbers seem ok yet my light is still on. Any ideas?
