ok heres the deal i hooked up my gauges and they all light up fine. I dont have the signal wire on the a/f gauge hooked up to anything but whenever i press the horn the gauge goes crazy and all the lights light up. I thought it might be feeding back through the ground so i changed the ground and it still does it.So any ideas would be great help. Also shouldnt my oil pressure gauge come up to zero when i turn the key on? Now it just stays down below zero. thanks for the help

 

mine goes to zero after but mine does the same thing as you i just press on the horn and the air fuel goes crazy..lol i really don't know.!!!

but i heard, because we tried it on another car and wasn't working also..so i think it's defect....and on the other car with a different air-fuel it worked..so it's probaly defect

defected????? mine works fine. mine does the same thing when u honk but only when my car is off. do you have the 12V connected?

 

i think there's a wire that goes to my fuse box but i'm not sure..is it the black wire..don't remember...

 

ya i have the 12v hooked up the only thing that isnt connnected is the signal wire and it only does it when the car is on.

 

bump

 

mine use to go crazy when i hit the brakes or turned on the lights. but i just switched the ground to the neg. on the battery and it worked fine.
try that

 

this is funny mine does the same thing when I honk it goes wonky , I have switched grounds as well as the power source and it still does it oh well. Just dont look at it when you honk

 

i try not to honk instead..lol!

 

haha... i had my gauge hooked up for about a year now and never really noticed anything like that. maybe cuz i never really use my horn. ill check if mine does that tomorrow though.

 

At least you guys have horns... (-.-) my a/f gauge works fine.
