66 200 , Autolite1100, loadomatic dizzy: ballast resistor

[sparkyj]

Do you need a ballast resistor with this set up?
I'm having rough performance with a rebuild project. Trying to rule out thinks one at a time.
Stalling, noisy vibration on new rebuild.
Stuttery missing idle. As far as i can tell the balancer is OK.

Having the carb rebuilt again, but realized this ballast resistor issue when doing some reading.
The car never had one. I swapped over to a 1 wire kit on an alternator I Had. It was originally set up as a generator.

this is a 66 engine in a 62 Ranchero.

Yes, I believe that the 66 LOM required a ballast resistor. If the wire itself is like the '67, then it should be a pink wire located behind the dash cluster.

Yes all 12 volt point type ignistions do need a ballast resistor to protect the points from burning. Later cars around mid 60's have a resistor wire instead of a ballist. Is it still stock wiring harness? If so check around the center of the firewall there should have been one or as bucfan1234 said look for the pink resistor wire
.

Thanks guys. it is a stock 62 ranchero harness. Might the ballast resistor be inside near the ignition switch?

I'll check tomorrow.

Thanks for the reply. Just got the carb rebuilt. The carb sat for 5 years and was just bad.
It seems to run pretty good now BTW, but need to check that voltage stuff.

Not sure on that harness, but mine was just after the ignition switch, connected with a bullet connector then coiled under the dash. It was a pink wire in my vehicle that looks like this:

If you have a shop manual for your vehicle, it tells you how to test the primary circuit, resistor wire, etc.

I missed that this was in a '62 ; I wasn't sure about a '66 . My info [and visual observation on my '631/2] shows there is a short red with green stripe wire at the ignition switch which connects to a pink wire which leads to the firewall connector block . You should easily see the pink wire just past the dashboard - looks pretty much like bucfan1234's pic . You can check with a voltmeter at the coil + connector ; ignition on - there should be about 3 less volts there than the battery if the resistor is in place and functioning properly .

This is such good information , I'm sure it will help many out there for years to come. Thanks!
