94 Z Blowing 15amp courtesy fuse
Anybody... I have a 94Z that keeps blowing the courtesy fuse 15amp. Sometimes it take up to 30min and sometimes right away. I have removed just about all the interior lights and even removed the radio. Any suggestions? Thanks...
The interior lamps, the radio, the hatch release relay, the amplifier if equiped and the alarm are on that circuit. the only suggestion I can come up with is to unplug all these, pull out the fuse and ohm from the the non powered side of the fuse connection to ground. Check for the non-powered side of the fuse connector with a voltmeter before you set the meter to ohms(use the lowest ohm scale). In normal conditions, with everything disconnected, you should see very high to infinite ohm readings. Now wiggle every wire you can think of on this circuit and have someone observe the resistance readings while you do. When they start changing you have found the area where you may have a wire touching ground. BTW check where wires pass through metal first as they are the most likely areas.
This may take some time so be patient and eventually you will find it.
