    :Cool: Hit it with a Hammer? Or try turning the starter motor with a spanner. I had a starter Motor burn out on our old Coachmen Classic. :Sad:

    Try shorting the solenoid out by jumping across the terminals to see if the starter motor then turns over. (put a screwdriver blade across but dont touch anything else apart from terminals)

    Could be dirty contacts inside it or it is stuck (hammer)

    Regards

    :Cool: Try looking right at the back and towards the bottom. That's if the covers do not completely obscure the view. :Wink:

    Check the oil in the genny. Mine is a Generac and without Oil it will not run.

    Even says so in the manual.

    Is your vehicle engine running when you try to turn the genny over?, if not try it.

    There is a rest button on the genny, if its popped, push it back in to reset.

    You have got sparks at the plugs I presume and the leads were marked and replaced in the same order?:thumb:I assume the plugs that went in were the same length.Am I right in thinking the engine still turned over after they were replaced?

    They are right there is an oil level sensor that cuts the genny if the level drops too low.

    Personally, I would start by removing the plugs after marking the leads, and see it if turns over then.

    Right!

    IF the starter motor turns the engine over.............

    IF you have a spark on a plug...............

    Pour a spoonfull or so of petrol on the airfilter or squirt some easy start into the air intake. (Dont have the choke on)

    It should then start (never fails)

    :RollEyes: I'm getting confused. Originally:-

    It would NOT turn over?
    Now it would seem it DOES turn over.

    As John says. A separate fuel supply to the carb. If it starts?

    Then there is either NOT enough fuel in the tank (believe me, several others had this problem)

    OR

    The fuel line is split. Try blowing on the pipe to see if it bubbles in the tank?

    If it does? Try sucking fuel from the tank. Be careful. It doesn't taste very nice.

    If fuel at the pipe?

    Then get back to us and we will offer many more ideas to sort it out. :Wink:


    One other thing. Does fuel spurt out of the pipe when it is disconnected and you try to start.

    where does the genny starter motor get power from?

    if the supply battery is getting flat the high amps needed by the starter will remove power to the ignition coils causing a lack of sparks.

    It sounds as though there are two problems to address.
    1. The gennie was turning over but wouldn't start. Now it won't turn over at all.
    2. Gennie not starting.
    First of all we need to figure out why the gennie isn't turning over. You said you kept trying to start it. Did it gradually slow down while cranking or was it a sudden failure to turn over? If it's the latter you could have burnt out the master fuse if it has one. You could have burnt out the starter motor or possibly the relay. I don't think it's relay as you can hear it clicking. Putting a multimeter across the large terminals to measure the voltage while someone operates the switch would eliminate those. No voltage possibly the fuse, possibly the relay. Full voltage would prove the relay is ok and point to the starter motor. Low voltage would indicate a battery problem.

    Hope it helps

    Regards
    Doug
