  1. 3.0714285 😄 is 43(ring teeth) divided by 14 (pinion teeth).
  2. Note the stack of spacer washers on the body mount in the right of the picture. This "factory" solution to raising the body looks like something from a back alley garage.
  3. When my old A6 compressor bit the dust, I changed over to the Pro6TEN. Bolts right up,works great, and is about 20 pounds lighter.
  4. Seems to be the logical place for it.
  5. Just a guess here... Possibly someone replaced the dimming resistor for the dash lights with a rheostat. This would affect the brightness when the overhead switch is in the first position.
  6. If you go to Bob Johnstone's site you can see the wiring diagram 5b for your interior lights. Simply add a switch in parallel with the door switches going from the red/wht wire to ground. Very simply, you are creating another "door switch". However, this will also serve to activate your ignition key warning buzzer if the key is in the ignition. Find the annoying buzzer and pull it from its socket. Nobody likes that noise anyhow! https://studebaker-info.org/Tech/Diagrams/AEC/aec.html
  7. I used an electrical contact cleaner (aerosol can) and a fine wire brass brush. If you disassemble the switch, know that the wiper is spring loaded, so open it carefully and note the order that the parts (wiper, washer, spring) go in.
  8. By design, these controls reduce voltage to the motor to control the fan speed. The quick and dirty way to do this is by adding variable resistance to the circuit. The down side to this method is that the variable resistor turns the excess power into heat. That is why these controls are typically located in the air stream. Mine had the additional problem of corrosion that caused poor contact between the wiper and the resistance coil that caused erratic speed control and even more heat. Replacement switches are available, but a bit expensive. I was able to carefully disassemble mine and clean and adjust it. Works as good as new.
  9. The rotary fan control has an "OFF" position when it is fully counterclockwise. It is possible that the switch is broken. Another possibility is that the PO mixed up the wiring at the back of the fan and temperature controls. That's easy enough to check by removing the four screws that hold the vertical panel and tipping it forward. You may need to loosen the screws on the horizontal panel a little to get the bottom tab of the vertical panel loose. A picture of the correct wiring is attached. But, before you get into removing the panel... This may be a dumb question, but are you sure that it is the A/C fan that you are hearing? There is another blower motor in the heater that is controlled by the 2-speed switch in the overhead console. You might want to check that first.
  10. I had the same issue with the belts on my '78. I took them to a local auto upholstery shop and they shortened them for a small charge. Alternately, if you google "auto seat belts" you will find numerous vendors who can supply the belt buckle in various anchor lengths. You may want to consider going to the semi-rigid type which eliminates a lot of fumbling to hook up.
  11. Rule #1 of discussing Avanti IIs: Never say "never" and never say "all". Some models came without glass covers.
  12. Just for fun, take a piece of wire and and ground it to the chassis. While listening to the radio, touch the ground wire to the housing of the antenna and see if there is an improvement in the volume of the sound.
  13. That type of fuse was used on the lighter sockets to prevent meltdown or fire if the element didn't pop when it reached the proper temperature. If you're not using the socket with the heating element, that special fuse really isn't needed. On my '78, I found that circuit was protected by a 20A fuse in the box. Since I will not be using the socket for a cigarette lighter, I reduced that to a 10A fuse for powering my plug-in Bluetooth converter/cell phone charger. Since you have an early RQA, I would think that your wiring would be the same as the Studebaker. IIRC, the black 14 ga. wire from the lighter socket is tied into the circuit for the dome/courtesy lamp circuit. If so, that circuit has a fuse in the panel. You can verify that by pulling fuses out at the panel. When you find the one that turns off the courtesy and dome lights, verify that it also turns off power to the lighter socket. The downside of using the lighter socket for powering phone/electronics is that it (like the courtesy lights) is powered all the time, regardless of the ignition key. So, if you forget to remove a device when you park, it can run the battery down. I intend to run a new wire from the lighter socket back to a fuse that is only powered in the ACC key position.
  14. Well said. Run, don't walk. These repairs would put you deeply under water on any Avanti II.
