    ok then i started up the arctic cat 454 quad project i bought as a non runner, it started and idled and revved fine, went to check the voltage at the battery and it was reading 14.2v at idle, when we revved it it dropped to 13.1v.......... also one of the yellow wires with red stripe going into the reg/rec plug was very hot and melted slightly. is it the reg/rec thats had it or the stator?

    I'm no expert ... but that sounds like a short in the regulator. And the voltage shouldn't have dropped when the revs rose.
    Do you have a multimeter? It's not difficult to check the stator and rectifier if you can probe the back of the connectors. Check the wires and connector for any damage and possible shorting - esp. if it's a "project"

    There are many tutorials on line. Here are a couple of short ones I found
    stator test
    reg test

    On the stator you check:
    - that windings have continuity (low ohms) and that windings to ground is open cct (high ohms)
    - that the AC volts output is the same across all phases at tickover, then at higher revs.

    On the rectifier check that the diodes are open in one direction and closed in the other.

    Do check all connections, earths (esp regulator's earth), battery terminals are clean and tight.

    we spent 3hrs cleaning and re-soldering a heap of connections to and from the cdi,reg,and earths. its made a big difference to the starting and running issues. thanks for the tutorials i'll have a good look at them in a while and see if i can get time to test them!
