2003 Honda Accord - Positive or Negative Electrical System

Home  \  Asian Imports  \  2003 Honda Accord - Positive or Negative Electrical System

Can anyone tell me what type of electrical system my 2003 Honda Accord has?

I've heard that many of the domestic and european cars use a negative based electrical system while the asian cars use a positive based electrical system.

I'll assume from the question and the terminology used that you know very little about cars or electricity. Your car has a 12 volt (technically 14.2) NEGATIVE GROUND electrical system. I can't think of any cars built after the early fifties that have a positive ground system.

I don't know where you're getting your info from but it's time to find a new source. You're welcome.

What I included in my email was an actual excerpt from an instruction manual I received with daytime running lights package. I didn't do a very good job of summarizing. Sorry. The actual wording:

There are two types of headlight systems used, Positive and Negative. In the positive systems (typically domestic and european vehicles) the 12 volts is switched to the headlight and the ground is constant. In the negative systems (some Asian vehicles) the 12 volts is constant and the ground is switched.

Does this make more sense?

vwhobo doesnt know what he is talking about.
Yes your car uses ground(neg. electricals)
But most cars today actually use positive so I dont know where vwhobo is getting his info but he is wrong.

Cars that use positive electrical =
All buicks except the 97-2000 regal
All cadillacs except 2002+ escalades
Most chevy's except some years of cavalier, avalanche, and astro
All chryslers except some sebring coupes
All dodges except ram pickups
All fords except new escort
Half of all gmc's
Honda civics
All lincolns
All isuzu except rodeo

yeah so the list goes on and on you get the point vwhobo needs a new source. But yes your honda accord is negative/ground wired electrically speaking. Your welcome.

I think you need to read your Fast and Furious magazine a little closer. I challenge you to name any production car built in the last 30+ years that has a positive ground electrical system. And please back this info up.

:read: dulux's first post and he goes straight for vwhobo :doh: That's a mistake... especially when what he claims is wrong :tard:

Especially when he is wrong. Especially when he's been challenged, has read the post and conveniently doesn't reply. Posting on a forum makes people mighty brave or it brings out the mentally deficient, I'm not sure which. Maybe both.

so odd how the two traits are often found together....
