aftermarket or factory alarm?

With the lack of large fuses at the underhood box, have you checked to see if there any fusible links at the battery? A fusible link looks a lot like a wire. How many wires are connected at the positiver terminal of the battery?

The fusible link is connected AT the starter. Look there for a wire that did not get connected back, or that may be brittle.

There is a fusible link, 15A in-line fuse, and the positive cable to the battery connected to that terminal.I did test the link with the light, but not the multi-meter. To Kenny: I was having a difficult time capturing a legible picture of the diagram, so I uploaded the electrical part of the manual as follows: 94 Nissan Pathfinder (Wiring diagram.pdf) and it's posted in the accessory manuals section. Page 7 of the PDF is where you can find the diagram. Always willing to learn something new.

Got it. The ignition system is the first step. So verify the wires coming off the switch and report back. Then we can go from there.Kenny

There is a Circuit breaker right next to Ignition relay #2. Have you located any circuit breakers?

No, I haven't located any circuit breakers.Always willing to learn something new.

Now that I think about it, there are a couple of small black boxes under the dash near the relays. I will take pics in the morning and post them. One of them may be a circuit breaker.Always willing to learn something new.

When I said next to ignition relay 2, I was talking about on the diagram. I have no idea if it is physically near that relay.

Kenny, here is the voltage for each ignition wire per the key positions that were given to me earlier: w/b 12.36v b/y 9v b/y 6.6v b/w 12.5 b/l 12.6Always willing to learn something new.

Ok, so the ignition switch is good. The 9v and 6.6v are most likely just 'read' speed on the meter... so I wouldn't worry about those. Let me look at the diagram again and see what is next in line. Another question, when you turn the ignition 'on' can you hear the fuel pump prime (very faint hum from the gas tank area)? Also, try to locate the ignition and accessory relays and see if you can feel them 'click' when you turn the key on. You may need a second person to help you.Kenny
