alt conversion and push button ignition 120-130 1968

Hello All,

After some reading I thought I'd ask- I have ouch button ignition in my car- are there any issues with the amp light working?

I am lining up the parts for the swap. A volt meter would be nice. leaning toward the 1 wire delco right now. Funds and time dictate which route I take. My daily driver is parked!

Thanks

    The "one wire" Delco is a bit of misnomer. What you want is a 3 wire delco. A big red wire that bolts to the back of the alternator and goes direct to battery, and a plug in that will have a small red wire, and a small white wire.

    The small red wire from that jumps directly to the big red wire on the back of the alternator, and the small white wire simply goes to your amp light (green out of your voltage regulator)... I think that's how it goes anyhow. Effectively making it a two wire Delco.

    There are one-wire Delco alternators, and if you get one of them, you'll lose your amp light without some other manner of wiring.

    Your push button start switch (not push button ignition, as ignition is still with the key) will have no affect on the amp light.

    Volt meter.. eh.. you can just wire that into any circuit that live when the ignition is on. Perhaps as easy as the cigarette lighter.

    The Delcos are not direct bolt up. You will need a bracket (preferred) or modify the alternator (this can ruin your option of using it as a core, should it fail).

    You also need to get one with the little plug in the right place... some have the plug where the engine block would be, or too close to the exhaust such that the wires get burned.

      hello All,

      Thanks to everyone for their input, really valuable! Especially matt b, and Ron Kwas I may be sending you a fuse box from a p1800 for refurb!

      matt- To be clear, there is no key... on/off toggle switch, and the push start.
      I have a cap and screw in place of where the ignition used to be on the dash.

      I think that's where I'll mount the switch for my aux lights once this is sorted out; I can turn on the car again.

      Cheers,

        Glad to be able to help. Often I cannot when it comes to electrical issues.

        As for the toggle... I'd sure like a 3 position switch for that.. perhaps down for accessory, up for accessory + ignition. If ever you want accessories but not engine, having the ignition on can be a good way to blow up your coil. If the motor is off but ignition is on, and the points are closed (or is it open? I forget), the coil will over heat, possibly to the point of literally blowing up, exploding.

        I thought it was a gun shot when I left the ignition on in a 544 and forgot about it and took a nap... then wondered why the car wouldn't start...

      Matt has all the details abolutely right... 120-130 1968

      ...I'll add that cutting away part of the Delco alt housing is not recommended, as it weakens the mounting boss substantially, which will lead to this...then you won't have an alt charging system, OR be able to warrantee the alt, OR be able to fix it, and you'll probably contact me for a kit and start over...


      See: http://www.sw-em.com/altkit.htm

      Cheers

        Interesting... I've never seen one like that. All the Delcos I've seen after cutting have had a solid aluminum mounting boss. My problem has been getting the cuts perfectly straight, or rather, not getting them perfectly straight, resulting in a broken mount/pivot bolt after time..

      About that small red wire, on my car I found that the alternator was sensing it's own output connected at the battery post of the alternator. When I relocated the small red wire to sense a load at the fuse box, the alternator came to life and charged better under various loads.

      Just to expand on what matt b wrote regarding the Delco alternator's orientation of the wire connections and mounting bosses --- The screws that hold the two halves of the body together can be removed and the front and back ends reoriented (don't pull them apart). -- Dave

    so what is "ouch button ignition" ?
    Push button perhaps?

      Yes *push button, was what I was going for... typing too fast.
      I want to ensure that my amp light and volt meter that I will add-on will work as they should.

      My new battery was getting no charge at all. After two days of rain the battery is done and I imagine my generator is too.

      Thanks in advance!

      Have you noticed how every stinkin car commercial these days has to show you the push-button starter like it's some sort of revolutionary invention? My parents '50 Ford had that. I'm waiting for them to "advance" to the foot button next to the gas pedal.

        That's funny, I get cranky watching those commercials as well.

        I guess it's like the Dodge people yelling out 'It's a Hemi all over the place as if it's the Hemi of years ago.

        Maybe they think it will make us feel like we are in a race car. Silly. I just put a push button on my rider tractor.Teh ignition switch was done... Doesn't do anything for it's performance, just get's her started.

        Also along that same line are those with the starter button under the gas pedal,Buicks if I recall, and some with the button under the clutch pedal.
