1991 honda civic dx wire problem

hi everyone,

I bought a remote starter on ebay called NITRO BMW-2 way remote starter. It's a crappy made product. The chinese company who made this couldn't even correct all the grammar mistakes in the user's manual. So it's kind of confusing. But I ALMOST figured what they are trying to see. There is only one problem which is:

how can I find the alternator wire ?

The remote starter obviously need to hook up with the alternator to know the car has been started. But I tried many diagram, they give me a white wire which is also the battery wire. It failed of course. So Can anyone tell me how can I find the right alternator wire?

Thanks!

a blue wire at the distributor = tach wire.

what's this white battery wire you're talking about -- is this off the alarm/remote starter brain?

Thanks for your quick reply!

Why does it connect to the distributor? Isn't it supposed to connect with alternator?

The white wire is from the car. It's a constant +12 V wire that supports things like cigarette lighter or clock or something.

Well, if they want you to do tach/alternator sensing, then the wire from the alarm/remote starter brain needs to be connected to an a/c wire, like distributor wire or alternator wire.

If they want you to do voltage sensing, then that is perhaps why they suggested you tie into the white 12 volt wire.

Make sure you know which mode the r/s is in before you tie in any wire.  Test all wires with a voltmeter

After some investigations, looks like the green wire (alternator wire) off the nitro brain needs to be connected to a 12 volt constant supply to do VOLTAGE SENSING.

remember, you still probably have to "learn" the voltage sensing to the brain -- usually this requires you to start the car (once all the wires have been connected) with the key and the brain will flash the park lights and/or honk the horn a few times to indicate successful setup of voltage sensing.  Then you can attempt a remote start after this.

Thanks peterubers~

But it has a wire connecting with 12 V . So I don't know what to do. I am gonna type all the wires here(there are some confusing english on the manual)

green wire: Air condition wire / connect keyhole ON wire

red: connect power supply power (12v)

gray: connect START engine wire

black: ground

White wire: direction indicator (I think they mean signal lights)

white wire: direction indicator (I think they mean signal lights)

second part

white: speaker
brown wire: trunk
yellow: relay connecting wire( they provide a relay)
blue: door trigger signal -
orange: door trigger signal +
purple: foot brake


gray: hand brake

green wire: alternator ( when successfully starting, positive, power is output)

***this green wire is the one confusing me***

I decide to ignore all those trunk and door and hand brake thing. So it would be easier to do so. But the alternator part, is really killing me.

Here is my translation:

Green wire: accessory/ignition wires --> I would connect this one to civic ignition wire (BLACK / YELLOW) and the other wire connect to civic BLACK / YELLOW wire

Red: 12 volts constant --> civic WHITE/ black wire

Gray: starter wire --> civic BLACK/ white wire

black: chassis ground

white wire: parking light output --> since there are TWO white wires, I can only assume one wire is + (pos) output, and one is - (neg) output --> volt test each one prior to attaching to the civic.  The civic is a RED / GREEN(-) wire at the steering column harness.

Green alternator wire: connect to civic WHITE/ black wire (same as above) -- will detect voltage sensing through this wire.

Green alternator wire:?? gee, the most important part is missed.

Thanks for your great help~

sorry, I was editing my post based on my notes.

Purple wire (must connect): civic GREEN / WHITE wire (at switch above brake pedal)

Hi peterubers:

I really appreciate that.

Now I attach the manual page within this page. see if there is anything I didn't say right.

Thanks again!

So here is a conclusion of what you said:

Green wire: accessory/ignition wires -> bl/ye

red: w/b

black: ground

white: parking light

green alternator: WHITE/ black



Second union:

Purple wire : GREEN / WHITE (above brake pedal)

so those two white wires (direction indicator) .. you can use just ONE of those to connect to the RED / green civic parking light wire. it does not matter which one you use. 

This system has what's called an "anti-grind" feature, hence the relay.  If you want to connect that, do the following:

Find the civic starter wire, cut this wire in half. You will now have TWO ends, a keyside and a motor side:

The keyside of this cut wire, connect to the 87a terminal wire on the relay provided.

The motor side of this wire connect to terminal 30 of the relay provided.

Terminal 86 of this relay should be connected to the civic ignition wire (BLACK / YELLOW)

As far as the Green alternator wire, i still think this must be connected to the WHITE/ black civic 12 volt constant wire to do voltage sensing.

What are the instructions for programming this module or teaching it voltage sensing?  Can you scan those as well?

-------------
The search function is your friend.

There is something called learning function. I think this is the voltage learning thing you were referring to.



Thank you!

That learning functions is to program a new transmitter to the brain... it does not refer to the voltage sensing.

Are there any other pages that refer to initial remote starting? What does pages 1 through 7, 9, and 11 and beyond talk about?

SOrry, but I didn't see any other learning thing on the manual. There are only 13 pages.

Here they are

wow... no offense, but I would not feel comfortable installing this in my car -- looks REAL sketchy/cheesy.

Best of luck -- lemme know if you run into any snags... which I'm sure you will (not because I doubt your ability, but b/c I doubt this product)

yeah, I was amazed by the crap when I opened the box.

WEll, I have no idea what to do.

The green alternator wire is still a problem. right?

by the way, I really appreciate all the helps you offer.

Thank you!

connect the green wire to the Civic 12 volt constant wire, as mentioned above 

Once you're sure all the wires are connected, I suggest starting the car with the key manually .. letting it run for 1 minutes.  Then, shut it down and initiate the remote sequence to remote start the car (this process is documented in the scanned pages of the manual you showed me)

HI peterubers thanks a lot!

Here are some wire diagram I found on the internet

I didn't see the WHITE/ black wire, can you tell me where you get it?

Thank you!

i'm not seeing it on that diagram either -- it may just be a white wire (according to that diagram)

Basically, look in the ignition wiring loom/harness and you'll test all the wires, and you'll find one that 12vdc always (meaning with the key in the off position, on and crank positions).

I tried the white wire last week. But it doesn't work.

The starter starts the car, but obviously it still tried to ignite again while the car was running, so the starter made some scary noises.

So, my guess is that the starter does not know the car has started. It needs a voltage detection or whatever to know that.

If white wire is always 12V, how does the voltage detection work?

Thanks!

J.C.

the voltage of the white wire drops during the cranking and starting up of the engine b/c the starter (the actual engine starter) is drawing a considerable amount of current from the battery, dropping its potential.  The r/s brain that uses voltage sensing detects this drop and knows that whenthe resting potential is restored, the car is running (i.e. the engine has started appropriately)

oh, i see now....

Do you have the secondary/hidden conrol box?

There are some connections for this box (it's in one of the pages you scanned in this thread)

One of things listed on that page is the "learning button."  I believe you are supposed to press this button before you start the car with the key, then start the car with the key, and it should learn the voltage sensing.

I still think the green "alternator" wire needs to be connected to 12 volts constant (i.e. the white wire will still do)

Did you use the learning button last week?

-------------

Sorry, but I don't have the hidden box. On the manual, it says "optional".

I tried the so-called learning function last weekend. but it does not help too much.

I have no clue now. I emailed them today, they gave me a number and asked me to call it.

I will talk 2 the people see what do they think. But honestly, I think they are as crappy as their products.

how much did you pay for this module?  For about $50-60 you can get a decent Ultrastart 1270TL remote starter, for another $20-30 you can get one with an alarm as well.

-------------
The search function is your friend.

I paid 69 plus shipping. So it's really a bad deal. If anyone ask you for advice, mention NITRO is the last choice they have

Well, lesson learned.

Just connect the green (alternator) wire to 12 volt constant (white wire) and FIRST turn the car on manually with the key.  Wait about 1 minutes, then shut down the car with the key, THEN attempt a remote start.

I will tried it later this week and see how it works.

I called the company today, and they even made me angrier.

They let me wait on the phone for 10 minutes transferring from one representative to another then hung up my phone.

Gee~ crappy company, crappy manual and crappy product.

Forgot to mention, the name of the company is called American Hi Fi.

Put that on your blacklist
