Ok I have a good running 69 Satellite 318 powered. Last saturday night the car kept going through batteries. Changed 3 times. Here's what I know. Before I left for the race on saturday I started the car like I always do to make sure its ok. It started & idled fine, but I did notice the amp gauge was not moving much as I reved it up. Left for the race any way. Car ran very good all night other than the battery problem. Tonite when I got off work I finaly got a change to check it out. I have 15.93 volts at the alternator. 11.65 at the battery. The only thing changed recently is the alternator. Batteries both ( I cary a good spare)are less than a year old. Regulator is 8 months old (new Mopar constant outut). Alternator is new reman. The amp gauge still only flickers when I rev it up. However the negative battery post is getting hot fairly quick. Or I should say warm. I checked the ground cable to the frame (trunk mounted battery) Its tight & clean. I also have a cable from the left cylinder head to the frame in the front. It to look ok. Have been running this set up for over a year now with no problems. So it looks like my alternator is putting out sufficent curent its just not getting to the battery. Any ideas. I'm not that good at trouble shoting electrical problems.  
Put a jumper across the amp to see if its the problem.
How much of the old wiring are you still using. Could
be at the bulkhead connector(if still used)

I think pretty much all of the bulkhead wires are still there. I thought about the amp gauge. Its the original one. If its bad should I get another amp gauge or a volt gauge? I'm also going to check & clean all the ground connections. I'll let you know. Hope I can get it fixed before saturday. Wanted to run footbrake at Piedmont. Thanks Mike 
With a volt gauge you dont put the amps through it
(or even a percentage of amps)... better off with a
volt gauge

The amp gauge is usually the problem, I would just bypass it or put a jumper wire across it.  with MR P BODY

Ok thanks a lot for all the tips & info. I probably wont have time to mess with it tonite, but hopefully thrusday night I can check the amp gauge. You guys are much appreciated 
The QUICK answer is to run a heavy gauge wire--at least no10, better no8--from the alternator stud to wherever your battery cable comes "up" from the trunk, as, starter relay, solenoid, etc.
the proper term is called "voltage drop" and old Mopars are now notorious. Think in your head the "path" going from the alternator stud around through the harness, to the starter relay, through the bulkhead connector, to the ammeter, a factory splice in the harness, to the ign. switch (and it's connector) AND BACK OUT through the ammeter, through the bulkhead connector AGAIN, etc etc. There's a lot of room for drop, there.
For example, put a meter probe directly on the battery positive, and, while running, put the other probe on your ign. terminal, either on the regulator, or the feed to the ignition resistor.
It should be nearly ZERO. More than about .2, that's TWO TENTHS of a volt is too much.

All of the 1969 Mopars had a big electrical problem, most of it was in the bulkhead connections on the 12V feed into and out of the amp gauge  All of the early Mopars,1957 to? ran all of the amps thru the amp gauge, not like the other car makers at all  As Mr Pbody says you can run a volt meter instead of the amp meter but make sure you connect the two big 12V feed wires together in the engine compartment or do as already suggetsed and run a seperate feed wire from the back of the alternator to the battery direct and run a volt meter then, make sure and isolate the volt meter so it does not read with the key on  If you don't it will kill the battery when it sits for a long time, don't ask me how I know  I have removed the 12V feed wires from the bulhead connetors and solder them together in the engine compartment and still fed them trhu the amp gauge, which usually solves the voltage drop Lots of ways to skin the kitty
