so i had my fd on the battery charger this weekend and i think it blew a relay.... i pulled it off the charger this morning to start it up and run a few errands, when i got back i put it back on the charger cause ive got such a wonderful pos alt... in any case i put it back on the charger and i instantly heard some clicking/vibrating noise coming from the fan relays, specifically the 3 ones that are the same. just replace them? or is this possibly an indicator of a bigger problem?

 

Test the relays according to the service manual procedure.
