My Car wa srunning great then I noticed the aAMP gauge in the discharge area , the car started missing then died , I installed anew battery just to get it Home and nothing , the alternator (big wire held on by a nut) the back of the alternator stud / bolt is really loose and was smoking (the wire is OK) when the Engine died , my question , does the power have to go through the alternator to run? if I buy a new alternator should it start? why wont it turn ove rwith a new battery? somewhere the connection is broken right? where do I start looking? there was never any smoke or smell coming from the dash area , the AMP gauge is now in the center nut nothing moves when the key is on , the fueable links by the fender mounted relay look good , this is a 1968 Plymouth Fury , thanks again.

I would look at the amp gauge in the dash. If the connectors aernt fried you can pull one of the nuts off the studs and just put the two terminals togeather for testing. However It sounds like you may need an alternator after that.

It goes through your amp gauge to the alternator. If the amp gauge is an open circut it won't start. Just jump the amp gauge wires. But with smoke coming out of the alt. terminal I don't know how much your alternator liked it. Jumping the amp gauge is an effective no cost way of diagnosis.

I'm not 100% sure on your car, but 99% of the time a crank no start on a mopar is a burnt amp gauge. I could be sending you down the wrong direction though.

lets start again. with the new battery in, can you get head lights? or dash lights, or interior lights? if the answer is no, then you need to back track your wiring into the car and see if that fusible link is actually burned out but looks good. If that is truly good(using a multi meter), then start checking power into the car. The amp meter is a good place to look and see if you have power on one side but not the other, then as said above, just bypass it. disconnect the battery, take the nuts off and move one set of wires to the other side and bolt it back up again. check again for power.
IF you do have head lights and dash lights but it won't start, see if you have power to the ballast resistor and then try to jump the starter relay with the key in the run position.
You could try that even if you don't have dash lights, but you won't have power to the ballast, but it will try to turn over the starter, and you would know it is just something stopping power from getting into the passenger compartment.

With key "on" need switched 12V to the blue wire to the "ign" side of the voltage reg (OE 68 "box" type I'm assuming). Need continuity in the green wire from the "fld" terminal on the other side of the "box" to the alt field terminal.

if no power to terminals then what to check?

go back upstream where the blue wire comes out of the bulkhead & seperate the 2 halves & see if the firewall half has fire and the brass male/female terminals in both halves are not burnt/corroded. If good there that blue wire circuit goes inside to the ign1 (run) terminal on the ign switch

Could the AMP Meter still be bad? it moves when you put the key on and whan you put the lights on , i just want to eliminate the AMP gauge , since it move sit is working right? , the Alternator charges on the machine and test fine (I wanted to eliminate too) all wires I have test and connections are clean and seem to have complete curcuits , I was wondering if I can drive the car 25 miles on just the battery with no lights on and the alt not charging , the battery has a full charge?
With the key on I get power to the big alt wire (12.66 volts) on the voltage reg wire I get a bit less than 12 volts , I cleaned the connections , still no charging.

Your ammeter is moving so it is good. Yes you can drive the car 25 miles with no charging just slow charge it up on the battery charger later when you can. It's not the best for a battery but not a 1 time deal breaker. Your alt is good. there's a reg or reg ground or field circuit (blue/green wire) problem. The simplest/best tool other than a VOM is some made up jumper wires with alligator clips on each end. Take off all field wires from the reg and alt and jump from the batt positive post to the "ign" reg terminal and from the reg "fld" terminal to the alt male field terminal & with a good alt and good reg & reg grounded it WILL charge. then figure out which of the wires you took off has an open (or is wired wrong) EDIT we posted at the same (approximate) time. You have the original 68 type "box" reg? and a 2 field terminal alt? then yes ground the 2nd alt field terminal (pick either one) to ground and the green wire to the other field terminal

Would a TWO 2 Field alt not charge? if both wires are not hooked up? I had a ONE wire alt on the car now I have a two wire? could that be the problem?
If you have a 2 field wire alt, ie square back, and a 1 field charging system, then yes, you will not charge with that configuration.
you can pick either field on the alt and ground it, and it should start charging. IF you have power to the VR and power going to the other field when the key is in run.
