gauge questions

[pro5dippin]

hey all so i installed my narrowband last week and so far its worked flawless. today i decided to throw in my voltmeter and that when i ran into problems.

now the voltmeter works perfect and now the narrowband isnt working and my radio wont power up.

i went thru with my voltage meter and i still have power going to all three pieces(voltmeter,narrowband, radio but they wont power up?

are you sharing power for the gauges; and is it an aftermarket radio?

Check your grounds.

Alot of people make the mistake (I did as well) The volt meter reading wire is to be attached to ur GROUND wire, not the power wire. If thats the case its a blown fuse.

ya i was sharing a wire with my aftermarket deck at but i have since severed that connection and i blew the radio fuse on the panel but the deck fuse is fine

Question; do you have to weld in an o2 bung for a narrowband sensor? Or do you only need to for a wideband?

[CrazyCaker]

narrowband you use the stock o2 sensor.
