Flickering Digitail LED Lights??

[70TWO NOVA]

I have a set of Digitails (Spaghetti Engineering) LED tail lights and front marker lights installed on my 72 Nova. They worked awsome for the first couple weeks then all of a sudden out the blue they started flickering on and off randomly. Only the brake lights (set to sequential) flicker. It seems to flicker more the higher the RPM. Anyone run into this or know why they may have started this? I was thinking alternator voltage regulator is going out but not really sure.
Thanks,
Brian

I noticed that mine were doing that as well once when I got out of the car to talk to the guy behind me. I have not looked into it to much yet but I was kinda thinking that it was happening because my car was just setting there at idle and maybe the brake pedal was vibrating just enough to loose contact with the brake switch possibly....in which case, I need to tighten that up. At higher RPM's I have not noticed it but then again....how could I from inside the car and nobody has said anything yet...lol

Guys double check ALL your connections. If you find nothing wrong, call me or call Brian at Spaghetti so we can get to the source of the problem. If it is a board, they will be replaced.

well i swapped out my boards with my brothers (same exact led lights) and had the same issue, im thinking either wiring somewhere or my alternator at this point.

Then more than likely not a board issue. Let me know what you find

Well i have been working on it all afternoon. Im pretty sure the boards are not at fault, but im having a hard time figuring this out. It seems like the ground wires at the 2 wire (orange/black) connector may have something to do with it though. When i move them around/push them in it seems to get better, but it wont go away completely. Im really lost with this one.

I have an American Autowire LED kit on my 69 Camaro that did the same thing. The LED boards are the Spaghetti Engineering sequential ones only this kit came with the entire rear wiring harness too so there was no splicing of wires. This kit is no longer available as Spaghetti Engineering took back the marketing of the boards. However I had the same problem with my tail lights doing a high speed flicker that I noticed while standing behind the car one day while it was running. I figured it might be my charging system but everything checked out fine. I have all new American Autowire harnesses throughout the entire car along with a new 140 amp alt. I checked grounds, connections of wires and everything I could think of and could not find anything. I also noticed the lights would flicker even if the engine was off ruling out the charging system. I called American Autowire and was referred to Spaghetti Engineering about the problem. I talked to Brian and he told me to send the boards back and that they had some problems with their early boards that American Autowire had sold. He quickly sent me a new set of updated boards that are much better. I must say though if you look closely enough you can notice a very high speed flicker in the lights that is barely noticeable. I guess it must be the nature of these lights for some reason. I would give Spaghetti Engineering a call as Brian was a super guy to work with and really wanted to make things right.

Give me call Monday afternoon. I will call Brian Monday morning and talk it over with him.

will do, thanks

Have you guys gotten anywhere with this issue? I just fixed a Vintage Air system that had a problem with a A/C voltage sending a small "ripple" through the system. Had to use an oscillascope to find it. Everything else on the car function just fine but the V/A module is very sensitive, this could possibly be the case?

[70TWO NOVA]

actually i have talked with Brian at Musclerodz and he is thinking there is a small amount of voltage noise in the system causing this. Whether its some ac voltage passing through im not sure, but he is going to have Spaghetti Engineering build me a set of boards with a filter in it to see if that helps, Ill be sure to let you guys know if it fixes the problem.

[MuscleRodz]

Did Spaghetti call you direct yet? I gave them your number so they could talk direct with you to correctly identify the problem. I am fairly sure by what you described it is voltage noise.

[70TWO NOVA]

no call yet, ill let you know if they do. Hopefully its what you said it was and they can correct the problem.

I had one faulty board in my chevelle set. One functions perfectly while the other one behaves very strangely...to the point of not shutting off with the lights despite the only hot wire being the orange constant power from the dome light. I called Spaghetti directly and they were great to deal with. As soon as I explained the symptoms they put a replacement board in the mail. Still wiating for it to get here. I was very careful to test every wire under every condition to verify the signals and voltages were identical on both sides to ensure it was a board issue and not wiring.

I had the exact same issue with my 72 camaro, I had two sets of boards wired in parallel (so two boards on either side)

They started doing that flickering, then they would not shut off, then one was out, all random things...

Turns out that these LED's need strong and perfect wiring. The wiring was fine from a classic car stand point and there was no shorts according to my testing. But one of the connectors was a bit old ect ect...

I ended up running new wiring for all the tail lights, still didnt fix the problem.

After trouble shooting I found a short on the front turn signal, didnt affect the turn signal at all. I rewired that turn signal and while I was at it checked all connectors to all my lighting system, found a weak connection on another blinker.

After I fixed the two FRONT blinker wires (again they were working fine) the rear break lights started working perfectly and still do to this day.

These are the spaghetti engineering ones as well.

yeah i was thinking it may be related to connections and wiring, but i went through all my wiring and grounds plus i have a new harness and came up with nothing.

[gmorris]

I received my replacement board, plugged it in without changing a thing and it works perfectly. Must have been some type of fault in the first one.

[70TWO NOVA]

yeah i sent mine back to Spaghetti Engineering and they are gonna fix em for me so hopefully that works out.
