 Posted: Mon Aug 18, 2014 6:45 am Post subject: Pushbutton Assembly and 12v conversion |
 |
|
I'm considering a 12 volt conversion on my 1964 Variant S.
Going from memory on 4 hours of sleep, I'm pretty sure I have all of the pieces to the puzzle:
*Bulbs
*Horn
*Electronic signal flasher
*Headlight relay
*Generator
*Starter with 6volt teeth
*Battery
*12v wiper motor
*Voltage regulator
*Coil
*Fan shroud
*Generator strap
*Chokes
What did I forget? 
One question remains:
What problem will I find when converting a pushbutton dash car to 12 volt?
Before I go diving in I'd like to know about how it'll affect the pushbutton assembly (if at all). I don't think there are any issues beyond the wiper switch which might not like the conversion without a voltage drop doohickey.
Any experience with a pushbutton assembly and a 12 volt conversion? What did you find?

| I been useing my pushbuttons in my 64 notch for the last 15 years and have no problems useing 12 volts. my wiper motor is still 6v and you just need to turn the switch to the slowest speed. |

Thanks for the input...I'd hate to roast the pushbutton assembly by overlooking something. |

That sounds like everything...
You can use a 6 volt starter. I used one for 16 years on my 66 Bug.

I've done that in the past...I have a brand new IMI starter with the 6 volt teeth so I'm going to use it. |

Putting an old Chrysler ballast resistor inline to the wiper motor works to keep the speed sane.
Don't forget the clock.

Got a link for that resistor?

Depending on which 12 volt wiper motor you're using, you might have to add a seperate switch to control the wiper speed. I did that, when I converted my 64 T-34 to 12 volts. The push button unit then just becomes an on-off switch. 
Also, IF your carbs have electric idle cut off jets, you'll need to swap them for 12 volt units. If you have the mechanical version, then you don't have to do anything with them.

Thank you...where does it go in the system? Is this keeping both the pushbutton assembly and the 6 volt wiper motor or do I have to replace the wiper motor with a 12 volt unit? Trying to find the most useful, least involved method.

Single speed 12volt wiper motor (unless Tram's idea works better). The car isn't going to be driven in the rain all that often...although I like your idea.
Carbs don't have electric idle cut offs so I'm good there.  |

Ok, so you're using the 67 only (12 volt variable speed) wiper motor? And not the 2 speed unit? If so, then it's just plug and play.  If you have a 2 speed motor (68 to 70), then you'll need to add a 2 speed switch.

Don't mean to highjack thread, but what kind of relay did you use for the horn and foglights on your type 34, Bob?

Standard 12 volt Bosch relays from KGPR. I basically kept the wiring stock, and used the 12 volt relays with 12 volt components. Plug and play. I should mention that I had to zip tie the relays to the bracket, due to them being smaller, but it wasn't that big of deal. Remember, I still have the 6 volt components, that go with the car, so I didn't want to alter anything.

Yes. 67 only wiper motor. I figured it's the easiest way to go if I have to pull the 6 volt motor out. |

It goes in the power supply wire to the wiper switch. That's it- no other changes.

Sure beats performing actual work in my book! Screw it to the firewall up under the dash- and if you really want to over engineer it, mount it to a heat sink first.

I used this style on my Bug, and really liked it. You can adjust the speed down to really slow, if it's just drizzling...

If he's using the 12 volt single speed wiper motor, then he shouldn't need to install a voltage drop, should he?
