Electric choke

RE: Electric choke
Make sure it's not the ground wire. It's prolly grounded through the carb, and the 1 wire you're talking about is the hot. If that's the case then it needs to be connected to a switched 12v, so it only comes on when the car is on. Some people hook it up to an alternator output so it's only on when the engine is running.

RE: Electric choke
i would have hooked it up to a ignition +, so that it kicks in when ignition is switched on standing or when engine running.
I don't really understand the alternator+ idea. Alternator+ is same as battery+ as far as I know. When engine is off it's 12V and when alternator is running it's 14V. Can someone explain this to me, or point out the connection number (or wirecolor) in the wiring diagram ?
I've never seen a connector that only then leads 12V when engine is running ?
if I take: http://www.hammar.dyndns.org/~djhamm...ng/1968/E5.jpg as reference, I'd hook it up to cable 16 ?!

RE: Electric choke
No, 16 goes through the resistor wire, he was talking about 35 the STA wire on the alternator. Its the wire used to basically turn the alternator on. Another (probably better) option would be to tie it into wire 904 on the voltage regulator, which is direct power from the ignition switch (runposition).

RE: Electric choke
The STA stud on my alt has no wire. The only wires going to my alt are a power and FLD oh and the ground. How about using one of the side studs on the solenoid??? From what it looks like, those don't have power until the ignition is on. Does anyone have an opinion about this?

RE: Electric choke
With the engine not running the STA terminal will not be hot. The STA terminal is the one the regulator uses to "see" the alternator output, but the field is what "turns it on". The STA is where electric chokes should be hooked up on an externally regulated alternator because it will not open the choke until the alternator is turning (ie: engine running). That is also why I said that if you are using a one-wire alternator you should use a oil pressure switch on a 12V switched source. With the oil pressure switch in there the choke also won't open until there is oil pressure (ie: engine running). What I forgot to mention was that the oil pressure switch needs to be one that has open contacts when there is zero oil pressure which is opposite of the ones that turn the idiot light on when oil pressure drops.
