Hi, I have a 96 civic hb and my headlights/ instrument lights flicker once I let go the throttle and let it ride in gear. I've check all the grounds and they're all in tact.

One thing I notice since doing a d16y8 swap in my hb, I didn't change the throttle cable so its a bit longer. On the throttle cable it has those metal rings so you can clip it down but I didn't clip it down.

I was wondering since its just bouncing up and down the metal rings hitting the hood, will that cause grounding problem? I already taped it up with electrical tape but its still day time so I have yet to test it out

btw... I've check the wires behind the intake manifold as well as the fuses so you can rule those out

 

Any CEL codes?

Have you tested the alternator?

 

Hi RonJ,

Yeah I've tested/changed the alternator, check the fuse 7.5, changed the eld, checked all the grounds if they're loose, anything I can find when searching in the search bar about flickering headlights/instrument lights on honda-tech I even check the wires before swapping the d16y8

 

When you turn the key to ON(II) (engine off), does the cluster battery light turn on and stay on?


CEL codes?

 

Oops sorry, forgot to mention no CEL and the battery light does stay on

 

Does the CEL work? Or have you connected a code reader?

Do you have a multimeter?

 

yeah connected a code reader no codes

 

 

yes I do sorry for the late reply had to drop a friend off

 

Do this test:

Warm up the engine and turn off all electrical accessories. With the engine idling, measure voltage across the two battery posts.

Turn on the headlights and the cabin blower to MAX. Again measure voltage across the two battery posts.

Post the two voltage readings.

 

alright

 

ok

engine on, accessories lights off: 14.27
engine on, blower max/headlights on: 14.06

took awhile cause I misplaced the wires for the multimeter...

 

No charging system issue was revealed by this^ test.

However, the flickering appears to occur under a different condition:

Have you check to make sure the alternator belt is tight? Does the cluster battery light turn on under the condition above when the lights flicker?

 

I found out whats the problem... When I converted my windows and door locks to automatic the connector floor harness are coming out of the connector so its shorting there... I either have to go to the junk yard find a new floor harness or just solder them all together

RonJ, Thank you for your help!
