All Lights Flickering inside n out!
 
I have a 2000 Honda Civic DX automatic...
All my lights are flickering inside and out.
I put a NEW 2 gauge ground wire from engine to chassis, no change.
It seems to be getting worse to the point where a small RED light comes on
below the Temp gauge with 3 letters. I can't make out what they are.
Then the red light turns off, when it's on they really flicker very strong.

When idling it flickers and so I rev up the engine and it seems to stop for a second but then starts flickering again.
When driving on the freeway any speed they start flickering and the RED light comes on more often when driving long distance.

I do have a check engine light on which is P0135 O2Sensor and so i changed the top one but the check engine light is still on!!!

I don't think or feel the two are related but who knows.

Can anyone help me with this issue? Don't want to get stranded with my 4 year old in the car.:confused::confused:

Sounds like a fuse 15 problem. Check fuse #15 under the dash. If it is blown, look for frayed wires on the back of the engine leading to the alternator.

mk378-On the left side under the dash inside the car I checked and see about 3 fuses with 15amps on them. When you say number 15 what are you referring too?
There are NO numbers on the fuses or cover! All the fuses are good, I tested them with a volt meter.

Also have the alternator tested.

7.5A dash fuse 15:

OK, I check all the fuses again and and they are all good.
The red light under the temp gauge is a SRS light that is coming on more and more frequently now. And they really Flicker hard when that SRS light comes on.

So what is the next step in process of elimination.

Check for battery voltage on the black - yellow wire at the alternator with the key on, engine not running. This same circuit also goes to the O2 sensors.

with the key on, engine not running...I used a volt meter and pushed the point of the lead into the blk/yellow wire where it goes into plastic plug. I could not remove it from the back of the alternator so i did it that way. It read 0.48 volts! It kind of fluctuated from .47-.49

That is the problem. Get underneath the car and inspect the wires. Confirm again that there is battery voltage on both test points of fuse 15 (i.e. from each test point to ground) with the key on.

ok, thanks I need to wash all the mud from the undercarriage first to be able to see. live up a dirt road, when it rains, it's pretty muddy.
What should the volts read?

mk378 01-29-2012 09:25 AM

About 12 volts, what you get from the battery with the engine not running.
