Well, I just about lost faith in my lude since I've been trying to figure out this insane electrical problem. Basically since I've done my wire tuck, battery relocation, etc... I've had a new problem that started in the winter, so I let the car sit untill now. It's getting nice out and my b-day is a week away, so I kinda wanna drive the thing! One winter night, I noticed with the key out, I could operate the heating fans with the key out. I thought it was a fluke and didn't bother thinking twice till the next day when I had some light out. Go to my car and the battery was dead! Checked my grounds, fuses, etc... and everything looked good. I was stumped, so I looked at my wiretuck and battery relocation, found I was getting a power wire that was showing resistance to ground??!!? Put the underhood fusebox back under the hood (instead of behing the dash/radio area). Damn near undid my wiretuck, checking my wires for a pinch somewhere, nothing. Then I randomly googled "bad fusebox /site:honda-tech.com", 2nd result was a post that I made, then I found another post about someone with the EXACT same problem. Granted it was in a 3g 'teg, the electronics couldn't be that much different. Turns out one of the A/C relays shorted internally and was backfeeding power to all the wrong things!

I thought to myself, no way a lil $5 relay can cause this big of a headache. So I pulled the relay, and tested it for continuity (just like the manual says). Terminals C + D (should get 0 ohms or close to it) was reading 1.13k ohms, wierd. I checked C to A then B, just for haha's (since it shouldn't read anything). I got 5-12k ohms of resistance, the exact same resistance I was reading at the wire I thought shorted out. I went back, checked the wire that I thought shorted out, and it was normal. Put everything back in mock condition, so I can jump the car, damn thing fires right up and idles like a dream!!!! Shut her off and checked if the blower fan still worked w/o the key and it didn't!!! HEADACHE SOLVED!!! Due to an annoying relay. Now I'll mount the relay in a different position, so it will completely avoid getting hit with water. Thanks to H-T, heres a on me!

Sounds like that 3g teg owners deserves an ebeer. Glad you got it solved.

 

I know, already gave em thanks, and many 's! Feel like a million bucks now the car is fixed finally, this has to be the ultimate "AHA!" moment for me lmfao. Help people out and learn something new everyday, thats what I love about h-t!
