Electrical Power loss

[Charlez]

Hey people

Basicly seem to be having a little electric problem at the mo!
My trip computer only shows PPPP on it, head lights are dim, headunit wont stay on and windscreen wipers are slow as hell. I have a new Batt in the car.
Basicly im thinking the alternator is my problem here but just wonding if anyone can think of anyother problems it could be.

Not 100% last night i was driving home and all died powerwise then about 2 - 3 mins later the engine died.
Batt seemed completly flat as i couldnt turn the engine over or lock the car with my remote. Came back 3 - 4 hours later started fine and drove home (2 mins drive) but all died again as i pulled up to my house. Again couldnt lock.

well i had similer probs on my old 320i n it turned out to be a drain from the starter motor! was very random too some days it would be fine others it would be a lil bitch! how did this all come about any simptoms b4 ?

also maybe a bad earth some where ? or faulty ignition switch but more likly earth or alternator or starter
you can get altonators and starters tested at a local auto electricians !!

Basicly just had an engine swap m20 for a working m20 . My m8s imidiate reaction was to blame a faulty earth but thats his answer to anythink even a flat tire. tbh i think its the alternater thats giving me the jipp. the bracket looks like its cracked but cant really see without removing the alternater. So will leave it till fridat as im getting a new one then. ty for the tips anyways
