Update:
As everyone may have realised, I didn't go last night...
Going through all the checks at about 745, just got the bumpers on. Topped up the oil levels, checked the tyres and cleaned her out. She was ready.
Drove her home to have a shower and get ready, then went to fill her up. Came onto the main road let the beast out, just outside of town.
Went around a corner towards the highway, and the charge light came on.
I wasn't too worried at this point, thought a lead had just fallen off. I pulled over and everything seemed fine. Except the Negative terminal on the battery.
I managed to drive her back to Dad's shop and we concluded that the alternator had overloaded. I was pretty wrecked at this point. I need a new alternator.
She was running very well with the new exhaust on her, best car ever. The sound she makes!
