Electrical Problem
Posted: Tue Oct 23, 2007 5:44 pm
Ok, explanation of the situation:
I drive 7.5 hours north of here to visit some family .... I get into my car on the way back home and I get the following situation.  I turn the key to "on", I hear my A/C turn on, interior blower turn on, ABS make it's clicky thing and my DRLs fire up ... about 1 second later, all of them turn off at the same time.  I turn the ignition to off, turn off my blower, start the car and everything works fine ... even after I turn on my AC again.
I make it the ENTIRE 7.5 hour trip home without a glitch.  Next day, at around 4:00am, I go to start my car, and my DRLs are "blipping".  They are off, and after about 5 seconds they turn on for about 1/10th of a second then off again.  This happens a few times and then they stop doing it.  My heater motor isn't working, nor are ABS, or my AC (obviously) or my DRLs.  As well, my alternator isn't charging.
I drive to where I have to go, only about 5 minutes away, and my car lives.
8 hours later, I go back to my car, start it, everything works peachy keen.  However, since that day (this was two days ago) none of the accessories I spoke of that turned off are working UNLESS the remote start is keeping the car running!
So, I decide to do some diagnostics.  The only difference between when my car is running using the key or using the remote start (from the fuse box's point of view) is that the remote start makes fuse 4 and 8 go hot.  This leads me to the conclusion that whatever feeds 4 and 8 (right beside each other) is toasted.
What I wonder about is:
a) why would my DRLs do the blipping thing?
b) why would it stop working randomly then work perfectly for 7.5 hours?
Some history is that I have been using my DRLs without the "light sensor" attached for about 1 year; this causes them to always be in low-beams-on mode.  I reattached the light sensor about a week ago, just a few days before the long trip.
So, if anyone can tell me what feeds fuses 4 and 8 as well as why questions a and b happened, I would appreciate it.  If anyone has diagnostic help, I would appreciate that as well.
If it matters, I don't believe my Beretta had DRLs when I purchased it ('94 from the US of A) but I installed a '96 Corsica DRL module so I could have the low-voltage highbeam option.  As well, obviously, my car is a '94 Beretta .. Z26 if it matters.
