Hi,

Careless removal of relays by rocking back and forth can spread open relay
socket pins. Relays should be removed carefully, prying from the bottom
or better by using a relay extraction tool such as Lisle # 46950

There's cheaper options from you know where, and you take your chances.
Loose relay socket pins and or bad internal connections in a relay can cause
arcing with high current DC circuits. This can lead to toasted relays and/or relay sockets and finally start blowing fuses.
If the relay coil contact is loose you might be hearing the relay coil
cycling the points at high speed, a poor mans buzzer.
See my post near the start of this thread.
