Default Charging Problems

I was driving home Saturday night, slowed for a bend and heard a bang. Looked at my dash and noticed the alt light was on and the voltmeter indicating around 12v (usually around 14v) Thought it might have been a drive belt, pulled over but the belt's OK. Got back in the car and noticed my guitar practice amp in the passenger front footwell had fallen over. Maybe this was the bang? But then what caused my charging issues? The alt light has never even flickered before, and the voltage always hangs around or just over 14v. Is there any wiring under the passenger side dash that my amp may have damaged?



Thanks
Ross

i`ve never heard an alternator go bang before, and i don`t think there`s much the amp could hit on the passenger floor that would do anything, perhaps it was coincidence the amp falling over and the alternator starting to die at that moment?, i think from memory my alternator, R.I.P carked it at about 180,000 k`s, no noise noticeable, firstly it would charge a small amount intermittently with light on, not long after it failed to charge altogether.
it might be time for a trip to the sparky?

I'm not even sure it was the amp falling over. I just heard a bang and then noticed my alt light on. Don't know what the bang was. I'll be calling the RACV soon to have a look.

G'day Rosscco, there is a chance the amp hit the ecu under the passeger kick panel just depends on how big the amp is suppose.

cheers,Maka

Well I just ordered a new alternator. Guess I'll find soon enough if it was the alternator at fault. It probably was, because I noticed it's covered with power steering oil, although it never gave any symptoms before.

if it`s covered in oil i would be looking into fixing the leak pretty soon , or you maybe buying another alternator down the track, they don`t like oil much.

Thanks. I got a new fitting for the power steering line. Just have to cut the old one off.

big chance if it`s an original alternator and had oil getting into it the copper part that the brushes run on will be non existent, probably good for scrap metal.

Well I fitted my new alternator today (and fixed the ps leak)
Good news - it's charging again.
Now I need to pull the old one apart, just for a look, to see what went wrong with it.
