Disregard the text labels; as I copied this diagram from another thread. Jumpering R/Y to L/B is OK as a temporary fix for your maybe faulty Safety Relay. The Safety Relay itself is very reliable. In the case from the above diagram, the problem was dirty , corroded contact points inside the relay. The other condition that can occur is a fault in the alternator that causes no current to flow on the yellow wire that triggers the relay. I suggest checking output on that yellow wire from the stator: it should be ~5 volts AC current @ 2000 rpm
