So the alternator on my '62 Valiant stopped charging the battery. The alternator was producing charging voltage but the ammeter never showed a charge, only a discharge. I traced this to loose connections at the ammeter, which now reads correctly and the alternator is now charging the battery...

Therefore the flasher unit will only operate when a load (the selected bulb) is placed on its output. If your turn signals don't work, try connecting a test light from fuse (3) to ground. The load provided by the test light bulb will make the flasher unit operate. The voltage source for the...

I could sure use a picture of how to measure the centrifugal advance on my Mallory YH by using the red plastic sticks they give you in the Summit spring assortment kit, because I'm not sure I'm doing it right. I've searched the 'net, including the posts and tutorials on this site, but haven't...

I bought the Mr. Gasket 928G spring set for General Motors because I couldn't find any other distributor springs nearby. Can I use these in my MP distributor? If not, where can I buy some heavier springs for it? (I seem to be having trouble finding Mopar-specific springs.) My MP distributor...

So some of the de luxe models of Mopars in the '70s and '80s had a large horn switch with a wood-grain inlay in the switch's vinyl cover. The switch consisted of a concave sheet metal base that attaches to the steering wheel; the base is covered by thin perforated foam in the center, and over...

Since the instructions tell you to be sure not to lose it, of course I did the opposite. I've looked all over for it. Not a sign of it. Those things sure can hide. Gonna have to make a trip to Napa Auto to buy a new one. You're supposed to use a roll pin punch to install it, right? Trying...

Is the distributor rotor on an RB engine supposed to point in a particular direction when the engine is firing no. 1 cylinder? I just replaced my timing set. I think the plug wires had been previously moved to compensate for chain slack. The rotor is now pointed toward no. 2 cylinder (the...

A friend and I are having a discussion on another forum, and I can't figure out if he's right or if I am, so I was hoping that maybe one of you smart guys could straighten me out. In a "Kettering" points-type ignition, does the condenser (by charging) serve only the purpose of preventing spark...

Standard Mopar EI distributor, orange box and MSD Blaster 2 coil. MSD says to use a .8-ohm ballast with this coil. My friend Mark, NM9Stheham (who is a smart guy), says that Chrysler recommends using a .5 or .6-ohm ballast with their EI. (I don't doubt that Mark is right.) To me this shows...

I have several older Mopars with the old-fashioned glass fuses, and they all eventually developed anomalies in various circuits due to poor connections in the fuse box. At first these issues can be difficult to troubleshoot because you might not find any open circuits with an ohmmeter, but when...

I find these quite interesting because they represent both the last dying gasp of the vacuum tube and its highest form of evolution before it was totally replaced by the transistor. These radios used so-called "space charge" tubes, which used only 12 volts on their plates, in the front end and...

I bought an NOS MoPar part no. 2291593 fuse block for my vehicle (see attached picture) because I had a plastic meltdown with the old box, but the new one is supplied with neither the fuse holding clips nor the hardware for attaching them to the fuse box. Does anyone know where I can get the...

On my 1977 and 1978 Chrysler vehicles, I keep getting this problem where my instrument lights and tail lights die. Upon troubleshooting, I find power at one side of the fuse in each circuit, but not on the other side, and it is not caused by a blown fuse. The fuse holder is intermittent or gets...

The horns on my A-body are really clapped out, and I need to replace them. Does anybody know if these Hella "Twin Supertone" horns are a quality item or not? If not, can you recommend a better quality horn, and maybe one that's not red? Thanks very much.

Del, et al: I'm getting a bunch of voltage drop anomalies. I know you've discussed this before, and I did search for it, but I couldn't find what I was looking for. If you don't want to repeat yourselves, could you please point me to the pertinent thread? Do you need to remove and clean up both...

This question concerns my 1978 D-300, but I hope nobody objects because it has basically the same electrical system as other Mopars. With the ignition in the "run" position but with the engine off, I get about a 1 volt drop between the battery and the fuse box. I guess I should try removing the...

A replacement voltage limiter costs $51.00. NO WAY!! I'm aware of the 7805 integrated circuit mod and want to perform it on my car: http://1962to1965mopar.ornocar.org/ml-instrument-voltage-regulator64.html But the above link pertains to a 1964 model-year Mopar. The parts book lists 3...

This isn't about an A-body; it's about my '78 Dodge D300 dually tow vehicle. It has dual gas tanks with the changeover switch on the dashboard. A couple of years ago the gas gauges quit working, so I went all through the wiring and replaced it and replaced one of the tank senders, and then the...
