iRoush Posted August 25, 2012 Report Share Posted August 25, 2012 Hey guys, as some of you may know I made a Custom Shift Light for my car. From the first time I started driving with it I've had a small issue that I never bothered to correct. Every once in awhile it would flash randomly, figured because it's picking up a random RPM pulse since I tapped right into the coil signal on the passenger kick panel, when I've been told that it's necessary for a tach adaptor on most shift lights to get a cleaner signal. Well, I just replaced a broken coil yesterday and now the light won't stop flashing and until I can get it fixed I just unplugged it. My thoughts are one of the following:1.) Need A Tach Adapter to get a clean signal2.) Need to switch back to Ford OEM Coils because I'm getting a faulty reading from the Accel Coils3.) Bad GroundWhat do you guys think? And for those that don't know this is the light:http://www.youtube.com/watch?v=U81tcAyQrvg Link to comment Share on other sites More sharing options...
SniveTroll Posted August 25, 2012 Report Share Posted August 25, 2012 it may be the signal. usually bad ground it wont activate. Link to comment Share on other sites More sharing options...
iRoush Posted August 26, 2012 Author Report Share Posted August 26, 2012 Just read some articles, the only shift light that doesn't require a tach adapter is the Raptor light. Guess I'll be ordering a Tach adapter and removing my solder. Link to comment Share on other sites More sharing options...
ttocs Posted August 26, 2012 Report Share Posted August 26, 2012 hard to tell since we don't know how you really did it. Could be the input, could be something else. Link to comment Share on other sites More sharing options...
iRoush Posted August 26, 2012 Author Report Share Posted August 26, 2012 (edited) hard to tell since we don't know how you really did it. Could be the input, could be something else.it uses a microprocessor that reads voltage pulses to illuminate the lights. The microprocessor according from the place I bought it from, measures the freqency of the pulses and will work with a variety of pulse shapes. The fact it reads different pulse shapes may be the issue I'm experiencing as it could be reading pulses other than the one I want.

ttocs Posted August 26, 2012 Report Share Posted August 26, 2012 depending on how sensative it all is it could be getting noise in from anything from a turn signal to a brake wire if its close enough. You probably would be better getting the signal at the source closer to the coil to ensure less noise. Link to comment Share on other sites More sharing options...
SniveTroll Posted August 26, 2012 Report Share Posted August 26, 2012 i use a tach adapter for the A1000. the 3 known tach frequencies i know is the trans, pcm and off coil #1. all 3 are unstable because of the large air pump under the hood.

SniveTroll Posted August 26, 2012 Report Share Posted August 26, 2012 for a tach signal it would almost need a ground loop isolator like some older stereos. Link to comment Share on other sites More sharing options...
ttocs Posted August 26, 2012 Report Share Posted August 26, 2012 never has an isolator that worked for a stereo. It was always a last chance/lets try this/danm it doesn't work either type of thing. Link to comment Share on other sites More sharing options...

4v Shane Posted August 27, 2012 Report Share Posted August 27, 2012 Need a clean signal ran into the same issue on my cobra. Also I would look into switching back to the OEM coils I've heard nothing but problems about the accel style coils or switch over to MSD if they are available???

I haven't had any real issues with the coils but I do plan on switch back to motorcraft. But for now it'll do. I've got a lot of little things to fix...

01yellercobra Posted August 27, 2012 Report Share Posted August 27, 2012 FWIW, my Raptor light would malfunction when I was boosted. Whenever I was on the throttle it would do the start up sequence like when I start the car. It hasn't done it since I've been N/A. I was suspecting spark blow out messing with it. But never got around to closing the gaps to check.Misspelling brought to you by Tapatalk Link to comment Share on other sites More sharing options...

I ordered the tach adapter, hopefully this solves my issue, regardless im becoming pro at soldering thanks to this crap haha Link to comment Share on other sites More sharing options...

iRoush Posted August 27, 2012 Author Report Share Posted August 27, 2012 ive had my raptor since 07 -08 and never had this issue.you also have a 96 which utilizes a different tach signal than 99-04. Link to comment Share on other sites More sharing options...

That's how my light is wired in and reading up on it a lot of people with 99-04's have issues wiring it up this way as it does not get a crisp and clear signal since 99-04's do not have a designated tachometer signal like the 96-98's do. the tachometer signal gets converted at the electronic gauge cluster whereas yours has a designated tachometer signal wire since the cluster is not electronically controlled.
