bought a new rochester 2gc fcarke

Post by dick2256 »

where is the best place to hook the wire for my electric choke
would the red battery wire on the alternator be a good place
that way it would only be on when the switch is on

It should be switched with the ignition. Test in the harness plug at the front left of the engine compartment. The best is the power feed to the coil but on the body side of it which will be 12 volts. The engine harness side with be a cloth covered resistance wire which would drop it down to 8 or 9 volts.

The illustration shows a portion of the engine compartment schematic for a 1962 (8 wire), 1964 (10 wire), and 1965 (12 wire) wiring connector in a Corvair. The multi-connector is always near the left-front portion of the engine compartment, near the voltage regulator location. The number of wires passing through the connector, and the color codes, vary with the model year. Locating the resistor wire that is connected to the ignition coil identifies a power wire that is switched by the ignition switch. Looking at the two halves of the connector can be a little confusing in the GM diagrams, as the wires make a left/right or right/left changeover in the illustration as the connection is passed over to the other side. The goal is to locate the "firewall side" of the multi-connector, and identify the wire that is tied to the resistor wire. This is a power wire that is switched by the ignition switch when it is in the ON position. Tapping in at this point provides a full 12 VDC switched battery voltage source before it is reduced by the resistor wire to supply the ignition system. Note that on a Corvair this supply wire is either 18 Gauge or 20 Gauge. If you choose to utilize T-Taps or Wire Taps, the correct color code for the plastic wire taps is RED (22-18 Gauge).

Splicing into a wiring harness wire must be done carefully. The article below was written for motorcyclists, but the information applies to modifying your Corvair wiring harness as well...
