Hey Im new to the forums, seems ive found the good place here, thanks for having me :-)This week I was graced with what i can only think to be an act of fate when today my uncle tossed me the key to a 1987 RX-7 N/A. After one night of driving it i believe I am falling for the car. Shes in almost great condition less thank 80,000km (canada ;-P). Of course most of these posts seem to start this way and then move to a somewhat frightened "tone" and something like "help i love this car but its so screwed up" Never the less mines not half bad, and it really wants some TLC. Mechanicaly, Ive made a tune up list that i have started going through already and seeing great results, however electronically I have some issues. Ive searched the forums and several others still coming up slightly empty handed. Perhaps some of you experienced RX-7 mazda enthusiasts could offer some insight.

My first electrical problem is that the front windshield wipers do not stop wiping. To temporarily fix this problem I pulled the wiper fuse. And I suppose will avoid rainy days? lol Is this a common problem? is there an easy fix before i start printing out wiring diagrams?

My second and much more annoying issue is that I cant stop this "interior chime" from constantly chiming while im in drive gear (automatic trans) I figure its a seatbelt warning chime, ive checked the plugs on the belt buckles and they seem fine, I tried jumping them with a wire still having the problem. perhaps anti theft but i cant seem to find if maybe a fuse that associates itself with the noise, I guess once It can be identified ill just remove the fuse providing its not on the same circuit as more important things Now I read something very brief that mentioned if certain things are disabled the ECU will charm at you all the time. However no engine/warning lights are on once the motor is started, and they all light up before the start so I know it cant be that. I also understand this is a way the ECU gives out engine codes however its ONLY when im IN DRIVE AND ROLLING. (sorry for caps just for emphasis not yelling :-) And i understand the ECU error beeps are on all the time.

Anyways this car is great and we are just getting to know eachother, please help if you can great forum great to be here great car!

Thank you and Regards!!!

well there are a bunch of buzzers and chimes in the interior. when you say rolling does that mean its stops after you speed up? becuase there is one when you are "rolling" backwards. can you describe the noise more? it low, high pitched? im not very firmiliar with ATs though

ziplock

The noise is a double beep as in ( Beeeep,, Beeeeeeeep) over and over again while rolling. It sounds very similar the the seatbelt beep noise. (seatbelt light does not go on, however it does flash randomly while the car is stopped once in a while and beep as it flashes)

The chime starts when the car begins to roll, both forwards and backwards.

It does not stop when i speed up.

It immidiatly and only stops when the car comes to a complete stop.

I would be more than happy at this point with just removing the 'chime box' if someone could point me towards the proper wire.

Hope this info makes it more clear

thanks

Power steering warning beeper?

Scroll down to the powersteering bit, and see if that describes your symptons

thats the "hey idiot your car is rolling down a hill" beep if im not mistaken. mine does it when i let it roll downhill with the ignition off. could be a bad netral switch. not sure. can you start the car in gear with the clutch unpressed? or start in gear in "D" if its an automatic?

dont remove the chime box. thats ghetto and it comes in handy.

the wiper problem is most likely a faulty switch. make sure the ground under the large "wiper vent trim" under the wipers is in good order and has clean metal to metal contact, no dirt or corosion. then replace the switch. you can find one in a junk yard or on this forum for cheap in the for sale section.

NCross, thank you for this information. You obviously know your mazda and are a big help. Do you perhaps know the name of this "hey idiot your car is rolling down a hill" circuit? Im just getting up and I will definatly check to see if she starts in D (yes auto trans atm) however if this is the reason for the beeping i'd be glad dissableling that circuit. Thanks again NCross, I will confirm very shortly as soon as I check the car (just grabbin some breakfast first :-)

NCross: So I tried starting the car in drive gear with no success. I guess the N-Switch is ok? Any other ideas?

well i wasnt sure if that was it or not, just a thought. i know a few things but not as much as a lot of people on here. try PM'ing Icemark. Mine beeps like that when i roll it around with the engine off. not sure exactly on the specifics of the circuits, but dont just cut the wires.

ziplock

Cool, will do. Thank you again

PS. I Have a GXL with the optional Teft Deterrant System. Perhaps this is the beeping?

i doubt its the anti theft because i removed mine and it still beeps.

Icemark

There is no such thing. What are you smoking???

Icemark

No, the ECU (the Engine or Emissions Control Unit) never beeps. It does not have any sort of beeper.

The CPU (body computer) beeps for lights on door open, Key on door open, seat belt for less than 15 seconds.

If you are getting beeps, it is (as mentioned earlier in this thread) more than likely the power steering computer reporting an error code, such as the tach not working, or the power steering pump disconnected or the speedo cable disconnected or a few other things.

Of course if that is the case and it is a beep, then you should have read the FAQ for FC sticky thread found at the top of this section before posting.

Have you recently been admitted to a psychiatric hospital?

i swear my car beeps twice when its rolling in neutral (IGN off). i just thought it was a "hey idiot your car is rolling down a hill" warning.... it does it when i pop start it. im sure its part of another system but ive never had it do that any other time.

Icemark

Key on and rolling (but engine not running), the power steering CPU will beep indicating tach failure

ok, sorry. i did know it was something that could be with the PS. I didn't know that its only for PS. I thought it was a safety feature of some sort as well.

Firstly thank you to those who replied

I did read the FAQ must have missed the part about the tach cause mine is non functional when i got the car, had a RX 'specialist' take a look at it cost me 3 hours rate for him to basically shrug his shoulders at me. I dont really know enough electronic troubleshooting to find the problem with the tach was planning on just sticking in an aftermarket tach any advice on trying to fix the tach myself or can someone please point me towards the proper way of just disconnecting this chime box?

Cheers

Tach has to work.

If it doesn't the ECU, Cruise Control, power steering won't work correctly.

The tach gets its signal from the trailing coils. If the tach is not working, then chances are the trailing coils are not firing or unplugged.

Wouldnt coils not firring cause the engine to run very poorly? she runs quite well, never the less i will check the coils, thanks Icemark
