The red wire running from the contactor to the hard start capacitor
Keeps burning. Replace the spade and it works for a while.
How can I troubleshoot this? Thanks

Either the spade on the capacitor is not clean so that a good soild connection is created when the spade connector is slid onto it, or the capacitor is defective inside.

Either insure the connection is good, or replace the cap.
