    Rb25 into 180sx

    Hey, so we took my rb out to get the engine bay painted , and since it’s gone back in I’ve no dash lights and it won’t turn over , but the windows , mirrors, heaters etc work? Any ideas what could be the problem ? It ran perfect before the engine cans out

    Thanks in advance

    Wiring problem somewhere.
    Being a custom loom there's any number of things to check, you've gotta go over it carefully to figure out what is wrong.

    Hopefully something silly like the ECU isn't plugged in.

    I wish it was something as simple , I cannot find the wiring diagram I had for it, so I’m sort of stuck until I get one , it’s odd though when everything else is working

    Poor ground one one of the main looms if you have just had it painted you may not have a solid connection

    I’ll have a look at the earths when I get home , when you put the battery leads on you can see the gauges light up very slightly

    If they light up a little bit it’s probably volt drop due to a bad connection

    Do you have a multimeter ?

    If there is one common on that connects to all the items then yeah
    like maybe one near the main fusebox

    I’ll have to have a look, it’s a matter of eliminating things now I suppose
