1997 QX4 - no power
I have a 1997 Infiniti QX4. My wife tried to start it this morning and it was totally dead, no lights, no clicking, nothing. I put a battery charger on the battery and one of the fuse/modules under the cover in the engine compartment on the drivers side started clicking and the battery charger wasn't charging. The fuse/module is labeled "headlight/security". Is this just a blown fuse or is this symptomatic of a more serious issue?
