why does our igniton system have a condenser
I didnt think a digital system required one?
Anyone? OD |
I am assuming condenser=capacitor in your questions, right?
assuming so, and with absolutely no basis to stand on here thats is specific to our cars ignition... I'd imagine any one of the normal reasons a capacitor is used. Filtering/smoothing, energy storage, coupling, reactance, timing... I think most of these can be ruled out very easily and a quick look at the design of the system should reveal the appropriate use in this case hard drive with the manuals is across the room, and no crutches/support within reach, or I'd go look for ya real quick |

ehh-hem. Sorry... continue :Peace: OD: could you confirm that you're referring to a Capacitor(s). and if you could expand a bit on it, I may be able to answer simply from an electrical view. (i just cant focus enough to picture things in my head on my own right now) |
Yeah, thought condensers were only used with old school points ignition.
|
a condenser is hooked up in series on the wiring harness that goes to the ignition coils. Maybe it is there for feedback? Whatever that means.
Thanks Paul--hope the leg is getting better--enjoy the lortabs! OD |
Odd, Would've expected all that to be done and hidden away inside the PCM. I cant even remember is the ignition system is AC or DC, but its more than likely just signal smoothing, noise rejection, or similar. I'm pretty positive it has nothing to do with the old CDI based systems.
Where is this thing at? I've never noticed it. Markings/size? |
it is bolted down--cant remember the oem location. I had to move it when i put my kit on.
Its in the work manual under electrical diagrams. |
Little black box that bolts down with a 10mm bolt to the earth plate over the engine? Just for noise reduction for the coil power afaik.

thanks for comfirming MM, this has been at me all day. (i'm gonna blame teh meds for being unable to see the function in my head lol ;) )
|
Ok so if you run without one--forget to plug it back up--whatever--what will happen?

/\ your radio will not like you
|
depends on the circuitry in the PCM, quality and location of grounding, etc. (I assume the noise filtering is to protect the PCM from high freq interference created by the coils/spark...)
given the right scenario RFI can entirely shut down electrical circuits from proper function. But I imagine it'd be a good idea to put it back just in case. |
The noise on the power circuit for the coils will cause misfires.

Anyone? OD N3A1-66-991 Condenser March 2020 EDIT: Mazda re-introduced this same Condenser into Series II production line after the first year of S2 make date from AUGUST 3rd, 2009 to end of production in mid 2012. https://www.rx8club.com/attachment.p...1&d=1291525771 |
Those have been used even longer than that. Don't think the part number would cross but FC's have something similar in them.

The FC had a small round noise suppression Condenser On the Distributor, PN 1757-24-334 (originated from RX-4), it was a simple job, screwed on outer Distributor Body as Earth and a single wire connector to positive power source. Only other condensers on FC was introduced from 1st April 1986 on the Alternator (single wire job again) and a square Audio Noise Suppressor or Condenser in Engine Bay mounted on Strut Tower FB01-66-991B...Some FC's had two of same part, the others mounted on Transmission...similar looking to the S1 RX-8. https://www.rx8club.com/attachment.p...1&d=1291537333 |

N3A1-66-991 Condenser https://www.rx8club.com/attachment.p...1&d=1291525771 |
Umm, to set the record straight, I was correct in what I originally said about Series II RX-8's DO NOT have this Condenser N3A1-66-991 like Series I RX-8's have ,
why, because I am always right and I am a know all of now over 40 years Mazda wholesale and retail parts experience. :mchase: My early 2008 (08/07/2008) built Series II RX-8 does not have this Condenser.....BUT.....after about 1 year of Series II RX-8 Production MAZDA Japan (Hiroshima line) re-Introduced this exact same condenser and used on Series II for the FIRST TIME, this was FROM Production Date AUGUST 3rd, 2009 to end of production in mid 2012. Why?, I do not have a clue, perhaps S2's were getting Radio noise from Coils, believe me if Mazda can save a production $buck they will. I will amend my original post. |
Noise reduction, 0.47 uf 250v
there is one of + of ignition coils other on fuel pump other on back shelf for trunk light And few specific design electric noise filter over brake pedal and other for rear defroster and Bose amp Some where between models they made few changes tho. Personally I add two other to my ignition total 1.41mf as I ruing D585 and I belive they need it ! |
what pn does the mag pickup from the pulley use? Same as FD? Better yet, where do I download the RX8 engine parts book?
