After you have gathered all of your tools, you are now ready to begin installing your ammeter. Strip ¼-inch of insulation from each end of the fusible link. If you are not comfortable installing the gauge yourself, ring using YourMechanic - a certified mechanic can come to your home or office to. Remember, it is always safer to get a new 120 volt branch circuit installed. Alternators with about a seventy amp available output were standard with air-conditioned models. With your materials in a sin where all tools and such can be reached easily, you should then locate the battery terminal on the positive side. Step 10: Find the wire that goes to the lighting circuit.
AMP gauges at the dash are troublesome. They should be by-passed, and then install a VOLT gauge. Dodge is not the only make with concerns about AMP gauge systems, early FORD Broncos, International SCOUT, and many old cars and trucks used the AMP gauge system too. With normal but frequent use, most of these Dodge trucks will have electrical wiring problems. The first to fail were often the trucks equipped with factory air conditioning. The air conditioning system adds a significant electrical load. The additional current flow when using the air conditioning and increased resistance with heat will break down the weak areas more quickly. With sufficient use, the non-air equipped trucks will also have electrical problems stemming from the same cause. Typical Dodge electrical problems result from a very antiquated power distribution system. The main source of power for the Dodge electrical system is based upon an old design AMP gauge at the dash and related wiring system. But the old AMP-gauge-at-the-dash system is not reliable with increased current loads of the more modern electrical system. Compounding the situation, the wiring system for the AMP gauge actually became weaker than it was over fifty years earlier. Assembly line labor was not so expensive in early years of the car. And it happens that Dodge was built with this terminal design, even at the main power delivery circuit. In summary, the AMP gauge and related wiring found in Dodge trucks of the sixties and seventies period was built with a recipe for failure. A 70amp alternator supporting powerful electrical accessories was typical equipment by 1979, and the load was too much for the method of wiring construction used. This feature clearly explains the shortcomings of using the old, traditional, AMP gauge at the dash. A good explanation of the AMP vs. THE HISTORY In some ways, the Chrysler Corporation was pretty far advanced where electrical systems were concerned. Chrysler gave us the Dodge, Plymouth and Chrysler line, and nowadays they all may be referred to as MOPAR. The AMP gauge circuit wiring had to deliver electrical current used by the entire electrical system, plus handle current to recharge the battery. Alternators with about a seventy amp available output were standard with air-conditioned models. And a weak terminal design was used where the AMP gauge wiring passed through the firewall. The large demand for electrical current often resulted with failures in the lengthy AMP gauge circuit, even in vehicles that were relatively new. The original AMP gauge system served as the main power distribution system. This circuit is the power source for the entire electrical system. And the fifteen amp capacity gauge at the dash worked fine with minimal electrical systems of that period. Current output from the small Model A generators was not even sufficient to support sealed beam headlights. The old Model A was equipped with a small light bulb backed up by a large reflector in the headlight assembly. Such a small amount of electrical current flow through good connections at the AMP gauge wiring was no problem with the Model A Ford. And with current output limited by a cutout relay on the generator, the AMP gauge could handle the small battery charge rate. GM also up-graded their system long before the Dodge Boys. And the new GM system could support a warning light at the dash. The warning light was often standard equipment and the gauge was an option. GM vehicles built with the gauge option also had a more modern design of AMP gauge at the dash. The newer AMP gauge was a remote shunt type design—a length of the battery charging wire in the under-hood harness served as the shunt. The dash gauge and related wiring no longer handled heavy current load. The plastic mounting area behind the dash is completely melted, and the lens and plastic trim is shriveled too. This gauge is included in Diagram A. Amperage is a measure of current flow, and all of the current used to recharge the battery was routed through this gauge—which caused the gauge to display the battery charge rate. Both the alternator and the battery were mounted up front, under the hood. And the AMP gauge was at the dash. It was an arrangement resulting with a very long wire circuit charging the battery. Large amounts of current flow through the AMP gauge will generate some heat too. The plastic cover at this gauge was only distorted by heat—but some Dodges have sizable holes burned in the dash where the AMP gauge used to be. Apparently, the shunt in the gauge has a sufficient amount of resistance to generate a damaging amount of heat with battery charging current flow. A previous owner had replaced the terminals at the back of the AMP gauge, and then did a weak by-pass of the gauge by taping the two wire terminals together. No doubt an attempt to get the old Dodge up and running. This connection is shown in Diagram A. These terminals were reliable with circuits of much less current flow, as with turn signal, clearance lights, and temp or fuel gauges. But the design was certainly not up to the job of handling the entire alternator output. This was a problem spot in the AMP gauge system that often made Dodge owners walk. This connection served as a pass-through for the main wire from the alternator to the dash area. When driving, the entire electrical system current load will pass through this connector. Also seen in Diagram A. Ignition, lighting, heater fan, accessories, and electrical power in general flows through the connector. The wire color code is black at this circuit, and this model was equipped with 10 gauge wire. Many earlier models had only a 12 gauge black wire. Arrow B points out the red, 10 gauge, battery charging wire. The plastic connector body surrounding the female flat blade terminal is beginning to melt away. And severe oxidation of the terminal itself is evidence that this terminal has been glowing hot. Notice that the other terminals in the connector body are still in good condition. The rusty appearance of this terminal is typical of wire terminals that have been hot while handling large amounts of current flow. If moisture had caused the oxidation, all the terminals would have been corroded. This splice is shown in Diagram A. The method seems to be reliable, as in thirty years of workshop experience the author has never seen a failure with this splice. When electrical power loss occurs, this is certainly not the first place to look for the problem.
