    Wiring help

    Ladies and gentlemen I bought a boat with a universal Atomic 4 engine it was seized so I went out and bought another Universal or no point in changing the engine compartments around to suit something that can be fixed with the same product.
    I would appreciate it if the Forum please walk me through wiring my engine to start without a key and an ignition switch.
    I would like to start with the alternator all wires then going to the ignition coil.

    A wiring diagram is attached.

    I presume you wish to start the engine out of the boat to get it tweaked before installing.

    When I did this I had some standard house light switches laying around that I used - worked like a charm.

    I would encourage you to use a switch of some kind to reduce the chance of you leaving the power to the coil on by accident.

    Hope that helps,

    Peter

      Remember to have the spark plug wires in the correct firing order 1, 2, 4, 3.
      I was getting crosseyed looking at the picture. Are 2 & 3 spark plug wires correct or are they interchanged?
