holley carb

9teen65coupe · August 16th, 2007, 07:09 PM

i am trying to install a holley 570 cfm 4bbl street avenger carb on my 1965 coupe equiped with a 289. the electric choke requires 12 volts. i know these cars originally came with a choke that opened from the heat the exhaust manifold made. but i also know that there has to be a way to get 12 volts other than the battery. also many other mods require 12 volts such as an msd ignition box. so if anybody has any knowledge on this issue any ideas are greatly appreciated.

jump a wire from the positive side of your coil.

9teen65coupe · August 16th, 2007, 09:04 PM

is it a common problem not to be able to find a 12 volt wire or is there somethin wrong with my electrical system? is something is wrong any fixes?

Run a wire from your battery.

cant come from batt.it will stay hot all the time and kill batt.most choke systems come off same circut as coil or alt.

Wire to coil is usually about 9Vdc. I believe For uses resistance wire for the coil. You need to add a 12Vdc wire from the fuse box to the choke that is switched on & off with key in run position. You will also have this problem if you go to aftermarket coil & ignitions (like MSD)

oldeer style ford coils and same year replacement had built in resisters.i have never had a problem hooking to them.later years and after market are a diff story.you are right

I do have an aftermarket coil and distributor. Both are MSD. Are you saying that i can just change the wires? I'm sorry but i dont understand what you are saying. Thanks for the hep

look under your dash and find the fuse box.take a test light and find a single connecter that is on and off with the key.it should be 12 volts.hook to that .

Alright I've found a switched 12 volt fuse. If I hooked up an ignition box from MSD would that blow the fuse or would it still function fine?

What amp is the fuse and how much amps does the MSD draw? How much amps is the fuse drawing now?
