what are the two relays (I think?), cylyndrical shaped electrical parts inbetween the computer and the altinater? What do they service? Mine has come loose from its plastic clip and is banging against the altinater. So now its dented and i was wondering if it was the cause of some of my electrical problems.ie: horn, radio,blower,a/c switches etc..etc.. all of these things worked for the first few hours i owned the car by the way. The moter is a m117 and the car is a 280 se 4.5 1972. All my regular fuses are intact inside and under the hood. No other electrical problems that I know of. And the car runs fantastic. Any advice would be greatly appreciated! iv'e removed this relay and nothing noticeable has stoped working. in fact my blower for the a/c started working!!? relay part #0005429719 what does this relay do??
