Starter Solenoid Sticking On

The B6AZ-11450-B (Motorcraft SW-7663) replaced the “A” version solenoid. The reference to the “A” (SW-3) solenoid is mainly for reference purposes. A small parts store with a slower moving inventory may still have some old stock or if still using paper catalogs (yes they are still out there) will not indicate the new number. I have also seen some of the original SW-3 solenoids show up on EBay occasionally.
I would use the SW-7663 and never look back!

No Officer...I really don't know how fast I was going, my speedometer stopped at 140!
Ok thanks secluff. Reason I chimed in cause I’m having a problem with my engine continuing to run when I turn key to the off position. I recently had my engine rebuilt and the shop put on a new solenoid, but I don’t know what brand it is. It’s definitely not a motorcraft. Just wanted to make sure I get a good one. I never had this problem before the rebuild.
