85 580CE 5-speed
I have an 85 280CE that's having problems with the 9-pin fuel pump relay. The original one failed about a week ago, so I purchased and installed a new one. Within 3 days and only 40 miles or so of driving, the replacement failed as well. I was able to jump the circuit to get the car home, where I then removed a rather hot relay. I don't know, at this point, if I have a defective replacement or a problem with the "load" the relay is receiving (could it have been hot just because the engine compartment is inherently hot? In addition, the ambient temperatures have been running in the 90 degree (F) range lately). Any suggestions? I don't want to try another relay (they're relatively expensive) until I determine if there's something else causing the failure. Anyone know what sort of electrical load I should be looking for at the relay terminal? PLEASE HELP!!! Thanks.
