Out of intetest.. you say it bumpstarted last night..??
And it had been 'jumped' with a 2nd battery recently
Was it driven??
I ask because the PAS uses lots of electrical power.. this would normally highlight a bad charging circuit..
DO keep us informed
What are you driving in August..??
I found it dead last Friday morning and assumed the kids had left a door open and drained the battery. Rolled it out of the drive and tried to jump start with jump leads off my Hyundai i800 but got nothing; not sure if I had bad leads or a bad connection to the battery / engine for earth, but I hadn't experienced "failing" at jump starting before.
Tried again that evening with no joy, so called out the breakdown service. He advised dead battery (was reading 10v or so) but agreed to start it up providing I signed off on him advising new battery needed.
Drove it for 30 minutes to try to recharge, but whilst driving along after about 20 minutes flashed my headlights for some reason, and the radio cut off momentarily, so I assumed it wasn't charging or holding a charge.
Parked up at the top of a hill just to be safe, turned engine off and then immediately tried to restart with the key. Nothing doing.
So rolled it down the hill and bump started without an issue, drove round in a circle and parked up on the hill again.
Left it 24 hours and did the rolling bump start again just to check a cold engine would start up, and had no problems.
I don't know if the "flashing headlights" anecdote above indicates something else about the electrics that has gone awry, but the £40 battery is arriving today and if that sees me through for the next 10 days or so whilst I still have this car so that I can sell it on, that's fine by me.
I'm getting a Peugeot e208. A bit different, a few more "frills" than the Panda, circumstances means its the right choice at the moment. Homecharger point being fitted today, hopefull I'll get the car early next week.
