I'm replacing a starter coil on a 61 Corvette. The manual

Customer Question

I'm replacing a starter coil on a 61 Corvette. The manual calls for the Primary resistance to be between 1-1.6 ohms the new one I have reads 2.5 ohms. is that a problem. The Secondary reading is within the specs.
JA: When you turn the key, do you get a single loud click, or a series of rapid ones?
Customer: I have not installed the new coil so can't answer your question.
JA: Are you fixing your Corvette yourself? What have you tried so far?
Customer: Actually the mechanic that rebuilt the car suggested replacing the coil to help diagnose the problem.
JA: Anything else you want the mechanic to know before I connect you?
Customer: I dont think so.

What is a "starter coil"?

Where did you purchase this coil from and did you tell them it was for a 61 corvette? Is this the original engine? Original ignition?

Expert:  Mike S. replied 1 month ago.

The secondary voltage or spark is directly proportionate to the primary wiring so any change in the primary will result in a weaker or stronger spark.

I see the 61 corvette had either a 4 bbl carb or was fuel injected. Which is this?

Customer: replied 1 month ago.
From a national chain.
Took in the "original" and did say it was for a 61 Fuel injected 283.

Great, Don't forget to rate me well, so I get credit. If you don't the deposit you made will just sit there and I won't get my share of it.
