I didn't close my driver's door properly when I got in this morning, so the little red light under the door was on until I tried to start it today. It turned over a couple of times before giving up. I took the battery out and hooked it up to the charger. In my haste, I put the leads round the long way. This blew to 20amp fuse in the charger. I then had to nick a fuse out of the car to replace that. I gave the battery 1 hour on charge and luckily that was enough to get it going. Will it work when I leave at midnight?
