insect buzzing sound 900

Exactly, I should have finished that thought and said any hot relays indicate a potential problem and can lead to melted and deformed relay sockets if it hasn't already started to happen. The top of any of the high current load relays may often be found warm under normal circumstances, but should not be hot. The fuel pump relay, especially the small Hella cube style as I recall, and maybe the headlight relay are often good and warm after a long trip. Things like worn fuel pumps and using high wattage headlight bulbs can aggravate the situation. It's actually worth occasionally checking for that so you know it's time to pull out and inspect the relay tray, including underneath.
