My 325i has just lost all the electrics...fixed it!!!

[lizard121]

Turn the key - nothing, not even any warning lights. never in 8 years has this happened before. Even the hazard warning lights and central locking are out. The battery is fine and I know is sening out power. The wierd thing is I only Went into Waitrose to get my dinner!! The thing was still hot when I got back. I checked all the fuses - all seemed fine so I'm thinking there must be as relay out somewhere....any ideas welcome.

Have just been down to 'Waitrose' again. I added a relay a while ago which I thought was missing that in the handbook drives the auxilery fan at 91dregrees. I removed the relay I added and she started straight away as always - just been for a spin to get upto temp and all seems just fine. Need to look into the missing relay point though....thanks for your thoughts anyway!

Earth strap ok on the nearside chassis leg?

Possible ignition barrel fault, mine has done this a number of times recently

I had this fault on a Cavalier SRI a few years ago - turned out to be the connector from the thick main positive cable to the alternator. It would either run like a bag of crap or there would be absolutely zero electrics - not even the interior light !

Spent ages trying different things to fix it then when it was going dark one night and I had managed to get it running noticed the connector onto the alternator was arcing. A new spade connector cured it.

Worth a look
