Little confused here. I've read some posts that the engine doesn't have to run to test to see if the choke opens after a few mins with the key in the on position. I have a 97 5.7 L 2bbl Mercarb with and electric choke. I think it's a Thunderbolt V, engine serial is 0k162383, but it does not have a knock sensor. It only has the ICM attached to the distributor. Attached is the electrical schematic for the thunderbolt V. It shows that the electic choke has it's own wire from the alternator and it is not spliced into straight 12V+ like some of the others. Does my engine have to be running with the alternator spinning for my choke to heat up?
I've already mostly winterized the motor and can't start it to see if I get 12 volt's on that circuit when the engine is running, but with the key in the on position and the engine off, it doesn't have any voltage on that alternator terminal. Does this terminal on the alternator only have voltage when running?
By the way, I did put 12 volts strait to the choke and it does open after about a minute. So I know the choke is good, but not sure about the alternator.
