Thread: B13 Relay question?

Under the hood of the car on the passenger side what is the relay box suppose to say? The green writing on mine is all worn off? My radio stopped working and I am trying to troubleshoot the issue.

Car is a 93 NX2000 w/ manual transmission if that makes a difference.

Did your dome light stop working as well? I had the same problem, my radio stopped working randomly and the dome light stopped, it ended up being one of the fuses

Passenger side is fan and security relays IIRC. I can snap a pic of the inside of the cover if you want.

Dome light, dash clock and radio are all not working.... Do you remember which fuse it was by chance? I pulled all the fuses under the dash and they looked fine?

Sounds like the accessory fuse for sure. Can't remember which it is off-hand. Test them all with a test light or multi-meter and see which is bad.

Definitely one of the green fuses in the box beside the battery closest to the fender. One of the square ones also known as fusible links. They will be kind of hard to tell that they are blown but there is an accesories one in there that handles the power to all of that. Just look closely at it and test it with a multi meter using the continuity test or just flat out replace it since im 100% sure thats where your problem lies.

I checked every relay I could find in the car and they all tested good.

It seems I am not getting power to the engine Electronics B fuse in the fuse box. Pulled the fuse and tried to hot wire the box and the test light wouldn't come on.... I really hope I don't have fried wiring somewhere.

The one in the engine bay has both hot all the time and ignition on hot wiring. The power to that fuse should be a hot all the time.

You might need to check the fusible links from the battery post to fuse box. Thats where that power comes from. I dont know if your still using the red connector box on the positive terminal of the battery. Its a pretty short track of wiring from there to the fuse box. The connection links to the main powers are meant to burn/open at those "jumpers" if something is shorted between the battery and the fuse box. Ive seen them to where they got old and brittle and broke inside but thats rare.

Best thing to do is pull up the FSM and find the wiring diagram for that circuit and trace it. Pretty easy to do. And ditch the stupid test light and get yourself a cheap multimeter. If you have a harbor freight near by they have cheap ones for $5 bucks. It will help properly diagnose the electrical.

OK, Is there a place to download the FSM for a 93 NX2000?

All the fuseable links tested good also.
