Missed this somehow. Pull the belt and spin all the idlers by hand. Either one has failed or the new alt. isnt lined up--or now both and thats the noise.
So, definitely run it with out the belt then.

Guys, I really appreciate all the help I'm getting. This site and community are always so awesome!! Thanks.

It sounds like an alternator alignment issue if the belt is off by a tooth after running. You may be missing a spacer. It's hard to believe you sent the alternator back multiple times and it doesn't work. When you say it doesn't work, is it not charging? Is your mechman black? The black ones are coated and require a separate ground wire to charge(this is good practice for any alternator on the cobra.)

No I got the aluminum Mechman. I have the 0 gauge wires for ground and positive leads. I wasn't supplied any spacers from Mechman. To be clear, I got it, put it on, and it stopped charging after a few days. I sent it back and when they returned it, it still wasn't charging and this ticking started. I just pulled it off again and will sent it out a second time, hopefully sometime this week. I'm sorry if I misrepresented the number of returns.

Gotcha. That's strange. Mine came with a spacer. I would check the alignment with a straightedge to the other pullies. Which mechman did you get the 175A? Do you have a fuse on the power wire from the alternator? Also, did you datalog the voltage or going off the battery light on the dash? Sometimes the supplied pigtail for the alternator does not get a clean voltage reading and causes a battery light. Mine only did it at high rpm(voltages data logged fine) and splicing the pigtail directly to the battery eliminated this problem.

I'll have to check the pulley alignment. I have an aerometer gauge and I watched the voltage as it dropped while I was driving around. That in conjunction with the battery light on the dash and checking with a multimeter while the car was at idle. Gauge and multimeter read about the same low voltage. When mechman sent it back to me they acknowledged that the regulator failed. But when I put it back on it immediately started doing the same think. Voltage began dropping off.

Check the belt alignment, the mechman I installed caused the belt to walk off the back off the stock lower, the belt would begin to hit something in a few minutes of run time it would rip the rear rib off the belt.

Interesting that the regulator failed so quickly. At least they're taking care of you. Make sure you request the updated pigtail harness if you don't already have it. They should supply it free of charge as part of an update. But definitely check the pulley alignment. That may solve your noise issue.

CJ428Mach: Will do once I get it back, thanks. I assume you still have the Cobra in storage, we never got a chance to meet when I was in KS, but thanks for all the help as always.

Keith89, yeah. I'm not sure what the deal is. I do notice a distinct buzzing, sounds like its coming from the BAP. So I'm think to skip all that non sense all together and do some pumps like I should've in the first place. I do have the pigtail but haven't hooked it up becaus

I heard back from CT Performance, obviously they just saw the video and can't really tell too much but are concerned it could be chain slap or a single cylinder issue (i.e. valve spring, rocker, or broken piston skirt). Ouch!

How in the world could this have surfaced when the car wasn't driven in between storage and dusting it off?

That's what I want to know. I mean it literally sat there for months. I'm kinda of ashamed. Its the longest its ever been outside. I've always garage kept it except for when I moved from Texas to Washington and from Kansas to Texas. Both times I left it at my parents house and they aren't gonna go hooning in my Cobra, that's for sure. It seems more likely that the belt is misaligned and causing issues but who knows. We shall see. Eventually.

Man hope you get her fixed quickly and cheap. Hit me up when you get your car to CS. Not many terminators around here.

Tell me about it, I saw a SY one the other day but I think that may have been while I was up in Killeen for the weekend.

Its tough to accept that about 99% of the time if a new problem shows up right after you mod your car....weeeelllll....

Well spend hours trying to find this magical problem that just showed up and in the end find out we fouled something up or the new part isnt working correctly.

If I lived within a half hour Id drive over and take the belt off and check it for you man!

MGoh3, your logic is sound brother. And I appreciate the offer. I really am leaning towards the alternator as well. Otherwise it just doesn't make sense that something internal failed after the car was sitting. FWIW a friend mentioned that it sounds like a pulley or tensioner when I sent him the video without even giving him the backstory so.....

Is your belt under excessive tension? I don't remember if you've said it yet, but have you tried taking the belt off and spinning each of the idlers by hand? Also, check the tensioner for binding. The fact that the belt was jumping a groove makes me think something is out of alignment like the alternator.

No I was so worried about it being something else that I didn't even consider the belt/idlers. I don't think the tensioner is under excessive tension, I don't remember exactly how much play it has.

From what I can tell just listen I'd guess the ticking is coming from here:
007039B0-85AD-44BB-8D26-877088B2C2D3_zpsf0igltla.jpg


But the acoustics under the car with the engine running are kinda hard to figure out. Also, that's not running on the S/C belt which you can see in this still frame is off by 1 rib, after I just fixed it.

I don't necessarily think the alternator is making the noise. But something that was changed or touched during the repair. Especially since the belt is off a rib. I'd focus on anything running on that belt.

Bearings for your idlers are a national 6203.
