Starter Relay
I have a 76 Ironhead, the starter relay wont engage on its own. I have an old rectangle relay with the numbers 1,2 and 3. I have the #1 tied into the battery along with the battery wire on the voltage regulator. I have the # 2 wire goin to the starter cylenoid and the # 3 wire is going to one side of the starter button, the other side of the starter button is connected to the hot side of the run switch. I can push the trigger on the relay with my hand and start the bike but when i push the starter button the wire gets real hot and the relay doesnt activate. Would you please help me with this issue, iam not using a harness so i need this in a simplified manner. I wired the rest of the bike and all is well. I am just having an issue with this dam starter relay, thanks for your time.

What year and model of ford relay did you get?
How does this relay wire in compared to the old relay? How is the relay activated? I have never wired in a 2 post relay before, thanks. I think i know which relay youre talking about. It has 2 large posts on the outside and 2 small posts in the middle is that correct?

Here are where the wires go on the numbered terminals of the relay:
Terminal #1--- Red wire attached to the #1 starter relay terminal goes to the 'BATT' connection of the voltage regulator.
Terminal #2--- Green wire attached to the #2 starter relay terminal goes to the small connection on the starter solenoid.
Terminal #3--- Black wire attached to the #3 starter relay terminal goes to the starter button.
Here is a wiring diagram for you.......... pg

Sounds to me like you either have a bad relay or your wire coming off the button is pinched or shorted to ground somewhere. Check for a short before you get a new relay.

I took the wire goin to my starter button out of my frame so its not pinched, if i am correct, the starter button jumps of off the rocket switch and gives the starter button voltage right? Then when i push the button that sends voltage to the relay which in returns close the magnets an sends voltage to the starter. I have the old rectangle relay on my bike is that the incorrect relay for a 1976 Ironhead?
