I have never seen one marked that way. They are usually marked IGN1 and IGN2. The terminal that is hot in 'run' position goes to the ballast resistor. The one hot in 'start' bypasses the resistor.
If you have an internal resistor coil, jumper the terminals. | | | | | Joined: Aug 2013 Posts: 59 Wrench Fetcher | | Wrench Fetcher Joined: Aug 2013 Posts: 59 |
