SORRY BUT THIS JUST AIN'T TRUE
All that needs to happen with your so called "1000 amp alternator"--or even a 100 amp is for the owner to
FORGET AND LEAVE THE LIGHTS ON when parked for say, an hour. The owner comes back, starts the car, and wants to drive off.
DEPEDING ON BATT RESERVE TIME OR CRANKING AMP, WHATEVER YOU CALLS...
bigger the batt more danger to come true that condition. That has been a tipical mistake installing bigger batts being an ammeter system.
of course everything needs to be rightly handled... AAAND, every accesory needs to be right hooked on ALT SIDE, not like every body makes, taking the power from batt side.
however IS TRUE you can't charge the batt back on car giving gas. If you are at home or close to a shop, get a charge there. If you are on the road, you can make it at iddle OR a temporally wire up to batt... depending also on amp output from alt
some good readings:
http://www.dodgecharger.com/forum/index.php/topic,62772.0.html
on one of them it is explained what RapidRobert said about parallel wires
NO NO NO NO NO NO NOOOOOOOO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Installing a small battery to PREVENT wiring/ bulkhead ammeter failure is WRONG THINKING.
And ALSO wrong thinking is charging the car at the shop just because the wiring won't handle it!!!
This is SIMPLE
If you need more amperage for fans, stereo, etc, you need MORE ALTERNATOR
and if you need these accessories and "more alternator" then you need
BIGGER WIRING
BYPASS THE BULKHEAD
ELIMINATE -or modify- the ammeter circuit.
My old '70 gave me fits "back in the day" and it only had the so called 60? 65? amp optional alternator. Started to melt the bulkhead connection and the dash up at the ammeter.
YOU CAN NOT go around building charging systems in such a way that you build traps into them
The best thing most people could do is modify the bulkhead and run LARGER gauge wires "straight through", and just bite the bullet and either do without an ammeter, or else convert to a "shunt" unit---there are a couple of people converting them
