Hi all. Just gota stereo fitted in the old fb (dont worry got all the trims and back bench remade so the originals are safely stored). After the battery running flat the first night i had it a look under the ignition switch showed they had put my stereo onto the ignition attatchment and moved the ignition wire onto the accessory, no wondetr the car wouldnt start up. Anyways to the point, even after fixing this the amplifier is drawing more power than the generator can replace. Is there any other way to fix this problem without attatching an alternator? and if not is attatching one something that can easily be reversed or would it not subtract from the cars originality? any help greatly appreciated.

I'd go the alternator way as its relatively easy I believe ( never done it and I'm no Auto Electrician however ).
There was a post about this either on this forum a while back or the FE/FC Forum.
The generator voltage regulator has to be bypassed and new brackets made for the alternator obviously. I think the Bosch alternators are still available new ( internal regulated ) but if you buy a reco one or a second hand one make sure its internal regulated otherwise you will need to buy an external regulator as well.
If you want to, paint it black and it will look a little more original looking and not stand out as much.
Just had another thought, I remember my Tech teacher telling me years ago that the generator voltage regulators could be fiddled with to increase the output but maybe still not enough to keep up with your stereo power draw......Reddo's a Sparky and I think Blacky's a sparky as well , maybe they might know.
Hope this helps,
Terry.

I can't think what to write here so this will do.
Alternator...and good quality battery (preferably one suited to car audio).
My old FC with its system could flatten the battery in 10 mins. I ran the biggest alternator I could get without rewiring and spent the money on a good deep cycle gell cell battery (1000cca!). I was then able to go to the drive in and with the stereo running at half volume last a movie
.
When tested was told with everything electrical running flatout even with the car running it would take 8-10 hours and the battery would be cactus, I only had two amps! But quite a few speakers

Speed and Style........... One day I'll get the speed bit.
I think i was told a while back 55amp Alternator out of a crummydoor works the treat, about to chase one up and get some bracket fabricated by a mate......my generator doesn't handle normal driving atm, let alone the stereo up full all the time (to drain out the loud exhaust).

Thanks all,
So even with an alternator attatched i could still be presented with problems? hehe maybe i should just get a comodor! haha id push my fb with the stereo on if thats what it takes before i do that. And wai-kiki i had the same theory as u, i didnt want to spend the money on some sound reduction so i just forked out tripple on a stereo! made sence to me haha.
Thanks again guys.

You can buy internally regulated 120amp Bosch alternators in the standard early holden configuration. It is common to see chrome 100amp Bosch or Delco Remy versions offered on ebay. Click Here
But by adding a larger alternator is not the end to your problems. The higher the amperage the more RPM required before it puts out a charge typically. So idling around with stupidly loud "doof doof" sounds will still see you with a flat battery.

All True,
What you really need to do is work out what all of your electrics are consuming in a normal situation (including doof doofing) and install a alterator rated at the similar amperage as well as a good battery. For example car running with lights fans wipers etc may consume 36 amps then a 55 amp alternator is the go. The bigger the alternator the more power it uses to drive it etc etc.
Most cars today actually run off the alternator and battery in conjunction with each other so the alternator is of great significance. You could also install dual batteries one for starting (normal) and one for the stereo (deep cycle) with a ignition controlled isolator so you will never suffer with a flat starting battery.
