How many ground wires are there on a 2005 honda civic ex special edition coupe?

Reason I ask is because when driving all my lights tend to surge constantly. I can especially see it at night. Sometimes it will do it, sometimes it won't. When it does, its bad. I've been pulled over several times because of it. Any ideas if its a bad ground wire or something else would be appreciated!

Hi it is not the wiring but the old battery it has had it's day and you need a new one.

The ground to check is the engine ground. In Hondas it is a wire that attaches of the top of the engine - under a valve cover nut was a popular place in earlier years but I don't know exactly where it is on your '05 Civic. The battery and alternator are grounded on the engine but almost everything else is grounded to the chassis. The engine ground connects those together and loss of that ground is famous for weird effects.

If you don't see anything obvious, test the ground. With the engine running and the headlights on, measure the DC voltage between the engine and the chassis. If it is under about 1/10 volt the engine ground is okay. If it is more than that you have found the problem. You may have to wait for it to act up to check it, but if you see the wire check that both ends are tight.

I have a problem of my own plz help. I swapped factory In dash CD changeling my o5 civic to a slim multi media receiver. Love it. Added a couple 12s and a couple amps evey things fine. Month later I see I have no taillights no tag lights or running lights. But the break lights work. Why. How. There both the same bulb.
