I just installed my Edlebrock carb. and don't know where to hook the electric choke wire up to. There was originally an electric choke wire but now it is eather gone or hidden some were. Cn anyone help on this one? Thanks, Mark B:confused:
Connect it to a switched 12 volt source, one that supplies 12 volts when the ignition switch is in the run position. DO NOT use the ignition coil 12 volt wire. Good luck.
Should not go to a 12 volt supply for the following reason. The application of 12 volts starts the choke opening to early before the engine is warmed enough. It's heating element starts to heat even before the engine is started. The proper place is the voltage regulator 'S' terminal. This location will only supply the voltage after the engine starts (alternator begins to charge), thus delaying the choke heating operation more closely fitting warm up time. If 12 volts is applied first and the engine stalls, the choke is already starting to open making cold idle running even worse.
Possibly, unless he has a setup like mine -a single wire alternator with no "S" terminal - which is a pretty common upgrade. My configuration has worked fine for about 9 years, but I like the idea of matching the opening rate more closely to the engine warmup time.
Hi Mark; Mine is hooked to the 'field' or black connection on the alternator. This is where Holley says to put it. Should be ok for an Edelbrock also. Good luck! Earl
Last night I was reading an olf Mustangs & Fords (June 2001) and saw an aritcle about swapping the intake and carb on a small block. They suggest hooking the electric choke power wire to the "I" terminal on the starter solenoid. Tom
Tom, I have found that Mag in error more than once over the years. Just because it is a big Mag doesnot mean there writings are always accurate. The 'I' terminal is the input of the regulator that has a 15 ohm resistor with the charge lite indicator in paralell and would limit the voltage applied to the choke heater in addition to being supplied before the engine is started. Reference the Chilton book page 44 drawing to see the choke connection to the 'S' terminal. Also reference pages 133,134 for how the stock carb electric choke is supposed to work on 73 up cars with the 2 barrel carb. As stated before, the voltage should not be applied until the engine is running, so that is accomplished from the alternator stator winding output after the engine is up to enough speed.. Sorry to go against the Mag but hope I have pointed out enough to make it clear for everyone.
Agreed, car mags aren't always right. I just happened to see the article shortly after reading this thread. The May 01 issue had a piece on inline sixes. On page 68 the captions/pictures are switch for Carter YF and RBS carbs.
