Have a 1996 Civic hx without keyoesk entry
​entry. Installed a Kenwood stereo and it won't turn on. I tested the red and yellow wires and the red one has 12v and the yellow one only had around 4.5v. Is this wire sippossuto have 12v? If so does anyone know what would cause it to only have 4.5? Even tried turning the car on incase the battery was low.

I have read some stuff about just running a new 12v wire from the battery for this. I was wondering if anyone knows how much power actually runs through this wire? It's the constant power wire for maintaining settings and radio presets. I'm wondering if I could just splice in to something that always has power like the dome light or something or would it overload that wiring?

Or if anyone can share what they did to resolve this that would be awrsoma. I'm sure someone else here has had this issue. Any help much appreciated.

The fuse for the yellow wire (which is a white and blue wire in the car) is under the hood.

12v-red- key switch and yellow is constant 12v for memory. So in theory you could run a new wire from the battery or a fuse that stays hot to the yellow wire on radio harness. But for the low volt prob that's weird

Thanks I will check this out when I'm off work 🤞

Really hoping to avoid this but might have to 👀😕

Hell ya this fixed it. I checked the fuse under the dash but didn't know about the one under the hood. It was blown, all is well now thanks !

Fuse likely blew due to 2 possible issues:
1. Orange ILLUMINATION wire not properly covered
2. Yellow BATTERY +12VDC wire touched the chassis.

I know this is off topic but did you ever solve that CRV Hesitation issue you had posted about in other threads? I'm having the same exact thing I've been STUMPED for months. Ive also just had the same stereo issue..which is SUPER weird lol. What fuse was it called under the hood? Ironically you seem to have all same issues. So I'm hoping you've had good luck, and have some answers lol..Anything helps thanks

The fuse is called "BACK UP". It is 7.5 or 10 Amps. Despite the name, it has nothing to do with the reverse lights on the back of the car. It supplies the memory in parts such as the radio, ECU, and dash clock (if equipped).

Thank you! Thank you! Fellaz! I'ma check it out! Now if only I could get this CRV hesitation out out the way... Ive tried and thought of seriously almost everything, jayj99crv has had the same exact issue with one of his, and the way he explains the symptoms are identical.

I recently bought a 1997 crv with 178k miles and had no issues on test drive or the drive home until almost all of the way home as I slowed to a red light that turned green. I went to accelerate and there was a ton of vibration from the engine and noise. Now that I have driven it more to figure out what's going on I am positive the transmission is shifting in to overdrive way too soon. Either that or the torque converter is locking up way too soon. I could be going 25mph and I will shift into overdrive and the car will be so bogged down that it canot accelerate. I have to give it a ton of gas to make it downshift and finally go.

I have taken the car to multiple shops for their diagnosis. They said the computer is communicating instructions properly, and the lockup solenoid is responding properly. So they would like to check out the TPS sensor next for 300$. So instead I replaced the TPS (and calibrated it), tested the lockup solenoid, cleaned the screens on the lockup solenoid, tested the MAP sensor, and drained/filled with fluid 1x so far (have only driven 20 miles since fluid change)

I refuse to believe things like "this is an older car, it does this now cause its worn out and tired." I understand it is 16 years old and has 165k miles. The transmission shifts smooth as butter and the engine is quiet and has no vibrations or noises other than a slight hint of belt sound. It accelerates smooth, etc. I swear it drives great for its age. There is some module or something telling the transmission to shift way too early. Someone else a few years ago posted on this forum their crv was doing exactly the same thing and I have sent him a PM and still no response, the forum didn't turn up any answers. This was 3 years ago so I was hoping maybe by now someone has had this issue and has found the fix.

My next steps I am most hopeful about are:
- waiting for a reply from the dude with exactly the same issue
- hoping someone who has had this issue or thinks they know what it is will chime in on this forum or another I'm on
- finding a specialty Honda shop that has technicians experienced in vehicles of this vintage
- maybe the computer/TCM can be reflashed? can they get goofy at times and forget their shift points?

LOL...That also goes back to what else jayj99crv said... "The problem here is this car was supposed to be for my girlfriend to relieve the stress she has when driving her manual transmission car."
