Mike: You may have a very serious and dangerous condition, occasionally found on older Chryslers. There are two large-diameter wires going through the firewall via the bulkhead connector. One from the alternator and one from the battery. They feed through the same size connectors at the bulkhead connector as do the smaller, lighter accessories and power users. Over time, the connection s on either side of the bulkhead connector can become corroded to the point of giving only intermittent power to the accessories while creating enough heat at the bulkhead connector to melt that plastic piece and allow other wires to short out, resulting in stinky smoke in the engine and passenger compartments. If you're fast enough, you can shut off the engine, yank a cable off the battery and put out the fire before it burns up your car. Later-year bulkhead connectors provide for heavier connection lugs for the main power supplies and can be used to replace the undersized connections. I did also add a fusible link, but have little belief that it would eliminate the problem as the overheating can come with normal current levels if there is a high-resistance connection. All readers would be well advised to inspect these connections and at least wire brush them clean and apply some conductive grease if they don't look too bad. Also, install a quick disconnect on a battery cable or have the proper sized wrench for battery terminals handy under the hood. Voice of experience in our '64K during restoration. A close call. Let us know what you find.

When it was popping it felt that the car was losing power. This did not happen all the time. I went to a car show yesterday and it drove fine . I went out to start the car today and it would not start as if the batter was dead. I just replaced the batter last month. I think I have some kind of electrical interniten problem. If you can give any ideas what I should be looking for.
