here it is hooked up to then Nissan L28et turbo engine using the VG30et controller to drive the ford IAC device. The Ford IAC was used due to fitment issues with the intake manifold. The original vacuum operated IAC did not seem to work out, but I may revisit that. One thing I learned, not demo in this video is the IAC did not become active until the operating temp was achieved. I may go back a...

    If you look closely at the "Solid State" legend on the tuner, the word "Amplifier" has lost its silver paint except on the letters "er". If this unit had been 100% solid state, it would have omitted the word "amplifier". Motorola did something similar with their hybrid units, with a wordy legend that was something like "Solid State Amplifier With Quality Tube Tuner". This tube tuner/preamp was the last tube tuner/preamp RCA made. It was reskinned for this model year to add the "Solid State Amplifier" legend as well as to remove the CONELRAD marks on the AM dial.

    My late brother had a CTC9 which was given to him by a friend when it stopped working. They mentioned it outlasted 3 newer sets. At the time (late 1970's) I replaced the horizontal output tube and it came back to life. I don't know where it is now, but I'd be willing to bet it is still working.

    I just started having issues with my CAS, and was watching your video about pushing on the plug. Mine would randomly shut off when hot, and sometimes missfire. Did some data logging with megasquirt and it ended up not showing crank signal at all. I took apart the plastic on the CAS itself and the Ground pin had a crack in the solder joint to the board. I bet ya yours is same! I got a different CAS but reflowed the solder joint and had no issues, maybe save it for emergency measures!

    Hi Dave, Got a question about one of your older videos on the ignition switch. When you put your key into the ignition switch, should you be able to turn the key counterclockwise to enable the electrical accessories only? When I look at my ignition switch the words "On" seem to be at the 12:00 position, the ACC at 11:00 and start at 1:00 position, lock at 6:00 and off at 9:00. Is this correct? Thank you for the great tutorials. Pat

    • @davewm9589
      @davewm9589 4 місяці тому

      yes you have it right. only things that stay live all the time is the headlight, emergency flashers and maybe the horn. they are always live iirc the ACC should be things like the fan/radio, no efi or ign. lock will make the door buzzer operate unless you pull the key out (and lock the steering if you turn the wheel)

      coming along. Got some gasket material to play with on the IAC, got the fuel pump connector all done, and tubing to finish off the return circuit. Will try it with the harness to see if it idles with the stock setup, hook up the IAC electrically but leave it unattached to see if it PWM's. Going to use a 20ohm resistor to limit current since I think the ford IAC was designed for a 5v signal (being safe anyway). This will go to the un used pin but will add it to your harness if it works. I am going to dig in your stash and see if I can find the OE IAC and get a ohm reading on the coil to be sure. Can try hooking it up and seeing what current it pulls as well for a verification.

      having some leak issues around the injectors (air leaks) where they plug into the head. VERY critical on exactly how the stab in, I tiny deviation in angle (due to the rail mounts) results in air leaks. I think the best approach would be to use the reg injector mounts to either hold the rail (like a large u shaped piece maybe 3 across).

      Much easier, really just removing pins, cleaning/shortening leads and terminations, just finished the pump relay. Only thing left is to fix a couple more leads (CHTS/AAR/knock sensor) and add the 6 /4 pin under dash connector (the wires are all set, just need to terminate them). Got all the injectors done,TPS done. I even tested the FP relay (ECU out, power to ign on and neg to pin 108 (think that is the one), to make sure the relay clicked (added diode to prevent reverse EMF). I wanted to make sure I did the diode in the correct polarity across the relay coil. Used a test light to limit current, all good. Thats pretty much the only thing I can see that could be messed up since all the rest of the wiring is stock, but for the added resister pack. I made sure the resistor load was always split between the two banks of 3, so on the 2 resistor pack I have inj 1 and 6, on the 4 pack I have the 2,3,4,5. That way during any injector event both resistor pack have current flowing thru them.
