STEREO AND CLOCK NOT WORKING

1995 Nissan Maxima

Electrical problem
1995 Nissan Maxima 6 cyl Front Wheel Drive Manual 215000 miles

After trying to replace the power antenna kit im my car (and failing) the stereo and clock in the car no longer turn on when the car is started. I tried multiple different wiring connections when trying to install the power antenna. I thought that it might be a blown fuse but I checked all the fuses that I thought it might be and none were blown. Currently there is no power antenna in the car and the stereo and clock still do not turn on.

Hi GregAl/ Welcome to the forum. A lot of Japanese radios have a 5 or 10 amp fuse plugged into the back of the radio. See if there is one there that is blown.

I checked the radio and was unable to find a fuse. I dont know if this matters but the current head unit for the stereo is an alpine that I installed a couple of years back.

Another thing of interest that I just noticed today is that my remote control keys ( that unlock or lock the car / trunk release) no longer work. Maybe that gives another hint to where the problem is.

Yup. I think you're going to find a blown fuse for the radio's memory circuit. It will be tied into a circuit that is always live such as your remote keyless entry system. Dome lights and horn are other common circuits. Look for two fuse boxes, one under the hood and one inside the car.

Thank you I finally found the fuse. It was the top right fuse (7.5 amps) in the fuse box on the inside of the car by the drivers seat.

A follow up question is about correctly installing the power antenna. I think I did this incorrectly initially which caused me to blow the fuse. There are 3 wires that come from the car that need to be connected: a black one, a pink one, and a black one with a red strip. I know that one goes to the battery, one goes to the radio and I believe one is a sort of ground. If I knew which one is which I could install the antenna. So if you could offer any insight into this that would be great.

If this is an original equipment power antenna, the electrical connector should match what's on the car. If you're adding an aftermarket antenna, there should be instructions with it that list the wire functions. There's usually a relay involved, but if your antenna only has three wires, it might be built into it.

You can try running the antenna directly off the battery with some fused jumper wires to see what works. This is just an educated guess, but my first thought would be black is for ground, black / red is for positive, and the pink wire on positive will make the mast go up and removing the pink will make it go down. If that works, your radio will have a switched wire that becomes live when the radio and the ignition switch are both turned on. That would connect to the pink wire for the control circuit. Many aftermarket radios use a blue wire for switched power for antennas and amplifiers. They are usually labeled too.

Check the fuses. That's what GregAl found and mentioned previously.
