Hi all so try to make this quick but as detailed as possible. So I had this honda for about a month and someone went into my car and turned my lights and took some stuff and thats about it so didn't think anything. Jumped car and it stalled, jumped again was acting super weird but ww got it home. Next day didn't start, jumped again had Battery tested, Alternator came back bad Voltage Regulator. Got a reman, and it worked for a bit went out about an hour away from home left use stranded, jumped again to take to autozone near where I was tested again as bad VR, we towed it home got a Brand New one not a reman, and we put it in and jumped it, acted weird again which is the same All Gauges go to zero, mileage clock goes off, but this was after we turned on the A/C which has always worked perfect no issues like that ever cars been perfect. But it seems like since the person went through my car left lights on and killed it I've had these issues and it seemed as if it was alternator, as the Alternator was OEM honda. Any thoughts, was gonna get a new battery cuz this battery has been jumped a ton but it tested as good but low charge so we have had it at autozone charging for an hour.

 

So got the battery charged drove it around and it was perfect, the PS was nice and buttery and perfect. She goes out this morning and it starts and she said it has been doing good, no issues but she was doing some delivery and she shut the vehicle off and it wouldn't start apparently, like 15 mins after she called saying it's perfect. So she's gonna go get it it tested again? Idk what else to do but to test these things. I'll updated but it seems super weird and if there's any input I thought I was gonna have to retract the original post because we thought it was perfect but here I am.

 

So kind-of at my wits end so I took it to get diagnosed at a shop for 120 bucks for them to say my ALT, Is bad and that I got junk parts for the 3rd time so I asked them what parts they were going with and got them put me ALT in and car didn't last between 3 uses before showing signs of doing the same thing . Thank god I got it home and then I shut it off and lo and be hold it doesn't start again...... they said they tested fuses/grounds apparently spent an hour checking .... just to tell me that the ALT seems to only be putting out 4 volts to the battery so it must be bad ALT. This cannot be the case I'm so confused.... I feel like everyone is out to rip me off with these Mechanics and this is between 2 of my vehicles, 3 completely different shops, they either messed with stuff that shouldn't been did, another literally ripped out my girls phone holder from her CD player in this honda which was MINT and fucked it all up, and they said well our guys wouldnt touch that..... LIKE WHAT.. why can't anyone now a days do ANYTHING right.

 

Tries a different angle of approach and went to a JY to grab an ALT off a newer 05 Civic, which was pretty new in the JY and we tried it and it worked for as long as any of the other ALTs have. Cannot figure this out when I had a mechanic I paid to diagnose say its bad ALTs from Hondas which is why I went to get a Honda alt and no dice.

 

Check under-dash Fuse No. 4 (10A). If that fuse is blown the alternator will not charge.

 

thanks for the response I'll have to check it myself, but as far as I know the mechanic I paid said he checked fuses and stuff and since we paid he said he will check it again but it's like come on..

 

checked fuse myself and fuse is definitely good

 

If you have a voltmeter, test the Blk/Yel (Black wire with yellow stripe running through it) at the alternator's green connector. There should be power on the Blk/Yel wire with the ignition switch in the ON position (car not running; but, switch position in ON).

 

So the mechanics verdict was still another bad ALT, but this one is slightly different it's charging at 12.85 volts with lights etc on but apparently when you use the blower motor it drops to 11 volts and that is also when the gauges die and the car won't start afterwards. He explained he checked the one wire going to the ECM and took it out of the equation, as he said and it should have told the ALT to put out full charge and it stayed the same. He showed going through the diagnostic tree of things to test that once he the ECM thing that to check the blk/ylw and if that has voltage change ALT was what was next, so I'm guessing he checked the blk/ylw also and just comes up to the ALT. I'm almost wondering if I should just put in a bigger ALT, I heard of people doing that for sound systems maybe I need one to run my damn car with the blower because it always kicked great AC at full power and now we need it for defrost, so back to trying to get a brand new ALT, atleast the JY ALT did something different. Maybe should try to get an ALT out of an 02 instead of an 05, shouldn't matter though, I think.
he also for the sake of testing replaced the ELD in the Fuse Box, guess it didn't make a difference

 

Did you ever figure this out? My mom's 04 civic is doing the exact same thing. I've checked all the fuses and pulled apart the harness and I just can't find anything that would be causing it to fail the way it does. I put in two aftermarket and one boneyard alternator and they all charge for about a week, and then fail. Battery voltage on the blk/yel and will charge 14v when you first start it but as it runs the voltage decreases to the point that the car just dies. No battery light comes on, but I know the bulb is good as it blinks during the cluster self check. Beyond frustrated at this point.

Thanks

 

hi so I did get the issue fixed but have no idea because I took it to a honda dealership and they quoted 170 for a diag and then the next day said they had 4 hours into and and checked the ALT and ruled that out, at which point I got upset and told them to stop working on the car as they wanted 580 at the time I called and said nope not paying, you said 170 diag and you didn't calcall.. so they said pick up the car at which point I did and when I was there about to explode on these guys they said "SOME WIRE" was loose and "everything seems to be working as of now" and so far for 3 weeks it has not had no problem.. so I have no idea what wire they were talking about, but I have a suspicious they were BSing me trying to get upwards of 1000 bucks out of me for a issue they found/fixed but wanted more time, but since I didn't pay for the full service they couldn't tell me hey we found and fixed the issue. But I'm now having another issue I'm about to post LORD HAVE MERCY ON MY HONDA!! and it doesn't have to do with this issue this issue is solved and I WISH I could tell you to help you but the guys at the dealership they SUCKED and they also smashed my mirror glass.... I really hope you find this issue because I was about 700 dollars deep into this issue just in diags, to not know what wire or what the issue is. I was just thankful It was solved

 

I'm glad you got yours straightened out! I guess I just need to go through and check all the wires again. If that doesn't work I guess it's going to Honda.
Thanks for the reply, I appreciate it
