For several months we have had intermittant problems with dead battery after a day or two of not driving. Charging system and battery check out OK. I blamed the problem on the add-on Sirus radio and Cell phone neither of which is trhough the ignition. This morning the battery was dead again and the relay to the PCM was clicking, The vehicle has 116,000 miles on it and had its 100,000 mile tune up last week and all systems checked out again OK,

Is the relay a part of the problem; an indicator to the PCM as a problem[ or just a result of the dead battery? Thanks

Check for a draw by hooking a test light between your negative battery cable and the negative side of your battery with the battery unhooked the test light will light up if theres a draw then starting unpluging things to isolate the problem I would start by pulling fuses the light will go out when you disable the right circuit
