Electrical Problem.

[Omer Khan]

Hi Eric.  

Chasing gremlins is no fun.  I have found that the factory wiring can sometimes be at fault.  The main feed from the alternator goes to the junction by the passenger side engine mount/strut tower/power steering fill tank.  Take apart those connections for the larger guage white wires and clean them with Emory paper.  Use dielectric grease and reassemble.   

For good measure on my own car I ran another 10 gauge wire from the alternator post straight to the battery.

When I was having charging problems I went through 3 alternators before I checked the corrosion on those connectors.  I also put in a first gen Altima alternator.  Same connections just swap the pulley with the stock SE-R one.  It is 120 amp I think.

Hope this helps!

I checked the ignition switch, grounds and fuses and they all look good but won't work when the alternator is charging at 14.1V. This car is 100% stock except for the aftermarket alarm which was installed long, long ago. I know electrical problems can be a pain, but with all those instruments going out at the same time means its one problem, I just can't find it. I plan on changing the alternator this weekend but doubt that will fix this issue.
