Ok, so I removed the radio a few weeks ago, and decided to install my a/f gauge yesterday. To make a long story short, its wired to the yellow/red +12v wire and the gauge doesnt work... I measured the current and whether the key is on or not, multimeter registers at 0v. Could this be beacuse I removed the radio??? Please help


Please see my other post for more details..

im not sure i'm getting what your saying but the red wire is your switched volts and the yellow is constant if you got them both together than its probably crossing something out...on the other hand you might want to just check all the fuses including the one under the hood thats the one that gets everyone...check the fuse box in the hood its a 15 amp fuse if i'm not mistaking....that one blows sometimes

 

sorry i mean I wired the + from the red wire with yellow stripe, and Ive checked the fuse under the hood, its ok, and its a 10 amp. clock/radio are on the same fuse and the clock works.. this is why its pissing me off so much.

 

well that wire should be live rather or not a deck is hooked up to the wiring harness or not...my next suggestion is use a fluke meter or a continuity tester to see if there is any power coming from that wire at all and then my next suggestion after that is to find another wire to tap into for u'r A/F ratio gauge

 

Umm i tested the wire with a multimeter thats all I had..it registered 0v but the clock, as I said before, was working.

Sorry, but I dont know what a fluke meter or continuity tester is. I probably should find another place to get my power from. What's a good place to do that? I wouldnt be asking but I dont have a Helms yet.

Also, does anybody know what's labeled 'signal power' in the diagram below for my ecu? Would that be +12v switched?

Don't tap into your ecu man thats not fun if u mess it up the only thing u should tap into your ecu is the wire u need to get the reading for a/f gauge...just run a wire directly to the in car fuse box to the radio fuse pull the fuse out either wrap the bare wire around one of the teeth of the fuse or use a fuse connecter from radio shack <too much work for me, when u can just wrap the wire around the tooth of the fuse and put it back in> and then you'll have the power u need when the car is on...also make sure u got a GOOD ground thats sometimes a serious problem easily overlooked

 

argghh the ******* incar fuse box.! shouldve checked there first.. it was a 10A acc fuse that was blown...

Fixed and working properly now!

 

Didn't i say to check all fuses INCLUDING the one in the engine bay...which also means the one in car on you well atleast you got it done
Haha i also noticed your avatar is the same pic i have as my wallpaper on my computer lol
