Went to my car yesterday (1983 mini 1000) and it turned over very slowly, lights dim, wipers hardly moving ect. So failed to start. A couple of hours earlier I'd just done a 60 mile round trip and all was well! Put the jump leads on and it fired up straight away. Let it idle for about 15 mins while I put things away. Set off to the garage for fuel but after about a quarter of a mile it started miss firing, lights where getting dimmer ect. Got to the point where no lights and would only drive in first gear, any acceleration and it misfired. Got it off the main road and that was it. Dead!
Tried to restart and nothing, no ign lights, nothing. Battery was completely flat.
Now I accept that a 15 min idle and half mile drive wouldn't recharge a battery but what would cause it to discharge so quickly? I didn't leave the lights on, there's no alarm/immobliiser, there's not even a radio haha. Plus it was driving fine earlier that day! Not had time to look over the car as it was late, dark and starting to rain plus it's now stranded half mile away till I arrange recovery.
I've looked in the FAQ re electrical issues/ charging ect and done a quick search. But was just wondering if anybody had any other ideas where or what the cause could be?
Thanks all and merry christmas
