now first off i would have searched this but the search function won't let you search "Zc" because its too short or whatever.....

Now to my delema. I finally got the engine to start but the idle is pretty high, like around 2K rpms. The check engine light came on so i pealed back the carpet to show a code 1 (i don't knwo what it was, but i thought it was bad ECU) so i slapped in the other ECU i had and the code went away and the idle dropped to 1100 rpms. Now my nissan is a piece of **** and it sounds like it idles around 1500rpms so i really hope that the ZC doesn't idle that high. I'm hopeing for a like 750rpms, or maybe 1K rpms

Any help is very great.


Also on another thing the battery light came on and it started to die. But i think thats the alternator going out and hopefully not a short or something else drawing power any ideas of how to check that would be awesome also

 

I had the same prob. Car idled high or fine, but when I would give it gas, the batt light came on. It was a ZC swap, and yes it was the alternator.


Checks................

1. Measure the batt load free (so not connected to anything) Should be around 12 V

2. Measure the voltage after you put it in the car. It should oly drop a very little bit.

3. Start the car and measure the voltage across the batt. It should be climbing to around 14 V.

Give that a go

 

ok cool, thanks man i'll give it all a go tomorrow when there is light
