clicking relays eh?

check and see if the car's silent internal alarm (if it has one, i dunno i dont do hondas) is activating due to a deep power flux. one way is to see if headlights or any lights are flashing (a lot of alarms do this).
If you find out this is what is the problem, see if the battery to the car is fully charged and connected PROPERLY and all cables are tight. then check your cable ground for the battery, see if anything is wrong with it.

to check battery get multimeter and make sure it registers 11 1/2 to 12v.
if not, charge it. in a couple of days test it again, if it isnt holding charge, check the alternator and determine if you need to change that too, if so, then change your battery too. I'm going to guess you have a leadacid battery so you're going to want to get that changed since they dont like deep cycling.


good luck.
