OK, here'* what happened today. I'm off to take my son to school, get in the car, turn the key, click, click, click. No crank. No time for this. Put the charger on it and took my son to school in the van. I knew what to check right away.
I get back home and pulled the battery cables, they looked good. Then I pulled the boots, yep, corroded.
Cleaned them up and starts no problem, go figure.
I'm sitting there and look at my areoforce, it'* not on, neither is my radar detector, I look down, no light for the intercooler pump. Those three things are on the same circuit. I look down, and the fuse I just installed is blown. So I change it, everything works. I shut down the engine and turn to run, still working. Turn to start and the fuse blows. What the heck? OK, what is blowing it. I have a switch on the IC pump, easy to check that. Turn off the switch and start the engine, no blow. Turn the pump on, it runs. Shut down and restart, fuse blows. OK, that'* the problem. I figure I'll start at the pump and follow the wire to find the problem. I ran the wire by the headlight and up past the horn so I check there. Wait, the wire disappears under the battery. Ahh, that'* not how I ran it. So I remove the battery. Sure enough, the wire must have dropped down behind the battery and when I placed it in there last time the wire got pinched under the corner. Over time it wore threw and started to ground out. Found the source of the short, fixed it, problem gone.
Dang stupid things. I have it clipped up and out of the way this time. I did before as well but it must have been knocked loose during the last big build. It'* the little details that bite you in the end.
