Ignition problems

Hello, got a drama with my Peugeot 407 54 plate. Last time I had a ride in it was yesterday, and this morning tried turning the ignition on and nothing comes up at all. I tried getting my mate to help jump start it and after some minutes of trying, only the electrics come up i.E radio, and dash board lights, but not the engine. I have only just gone back to try and this time nothing at all comes up. Any advice will be much appreciated, please

Measure the battery voltage. It must be 12.6 volts if it's fully charged. If it is, there is a bad connection, most commonly where the smaller positive wire bolts to the under-hood fuse box.

If you find around 12.2 volts, the battery is okay but it is discharged. Suspect the generator. You'll need to charge the battery slowly for an hour. A jump-start should work but you have to be sure the connections are solid, and it can take a few minutes to charge the battery before you try to start the engine.

If you find closer to 11 volts the battery has a shorted cell and must be replaced. Jump-starting usually won't work because you can't get enough current through those little connections.
