engine swap help !!!

[rakram]

Please help us:

We've got a 90 Civic 1.5l in wich we had swapped the 1.6 DOHC CRX engine from a 90 car. We also changed the wiring (as told) but i've got a electrical problem.

I've got voltage on EVERY cable when i turn on my key. When i turn key into off position i've got no voltage at all !! (exept for some cables)

What is wrong !! I am pulling all of my hair because i'm getting crazy.

Please help me.

Well... could you be more specific? If your car is on, voltage will be supplied to most of the wiring... If the car is off, you will still read voltages on the wires that are connected to a positive source (for instance the battery cable)...

What engine did you swap in?

Hi,

i'm sorry but i am not so familiar with engine codes but the engine is from a 90 CRX 1.6i DOHC (no VTEC).

Do you know what engine this is?

I know that when you turn on your key most cables will have voltage, but in my case we have voltage on about every cable there is !!
And when we turn of the key, usually you must have a voltage on one cable by the ign.switch (key). This is the cable wich comes from the battery, right ? This one also doesn't have any voltage with the key turned off.

also if i turn the key into on position my meters won't work properly.
If i turn my signal the lamp of the check engine goes on. If i put on my bright light the lamp of my turn signal goes on !

What did we do wrong ?


Are there also technical electrical schemes on the internet on both the Civic as the CRX ?

DOHC????!!!! I would have to say it is a ZC.....

First off, vehicles which require an ECU for the engine (most of them after 1970) have a little more complexity then simply one wire with voltage and several without.

Secondly, if you want the wiring diagrams, get a Helms manual for the model you want and it has all the wiring diagrams related to that car..

As for engine model numbers, familiarize yourself with where the engine stamp plate is, it will have the model number stamped into it and look something like B15B2.

Jesus, you guys sure fucked up something.

I would also agree that your engine is a ZC

I knwo that this is a little more complexer than i wrote, but i did that so that you would understand me, because you still have to agree with me that what i have now sure isn't correct !!

Where can i get the Helms Manual ? Does it seem to be online anywere ?

^^^ thats pretty much the same thing my car did when i tried to use the gauge cluster from an 88 CRX in my 91 hatch
