  • Generator wont start !

    Posted by doris on June 4, 2017 at 12:55 pm

    1990 Marathon prevost XL, Martin generator, never had a problem but after my last shut down of the generator it wont start again! Neither of controls work, front back and on the gen itself, not even a click?

    Moved for Andre.

    Start checking at the battery for battery voltage and tight cable connections. Follow the battery ground wire from the battery to where ever it goes and make sure it is a tight well grounded connection. Do the same thing with the postive cable, start at the battery and follow it to the starter. Make sure all connections are tight. Check the smaller wires on the starter solanoid and make sure the are tight. Sounds like either a dead start battery or a connection has come loose some where.

    Check all the easy simple stuff first, before getting to worried.

    We have experienced this exact same issue before. By toggling the generator power button (above driver) on and off a couple of times it should work. Ours sticks sometimes.

    Thanks has the start option on the generator, when dc power is on starter has power on. No power to the start togle switch, starter works when bridged with screwdriver but doesnt run, batteries are new.

    You’re getting lots of great advice from some pretty smart and very experienced people.

    Consider calling Jim Martin at Martin Generators:419-782-9911

    Jim@MartinDiesel.com

    I met him at the PRI show in Indianapolis last December. Even though we have a Wisconsin birthed Kohler in our coach I found him to be very engaging and very knowledgeable. I should be another good source of ideas for you.

    I wish Martin Generators was an advertiser on this web site and their staff monitored the postings.

    On our coach the “GEN DC PWR” button sticks just enough to remind us who’s in charge. Cycling it a few times and all is good. I tried attaching a photo.

    If you open up the main control box the start signal is actually a ground signal. While pushing one of the start switches make sure you are getting a momentary ground pulse on pin 1,9. The stop signal is also a momentary ground pulse.

    pin 1 or 9 should have continuity to ground normally. When you push start it ties the other one 1 or 9 to pin 2 which is ground. You can try jumping 1 to 2 or 9 to 2.

    I sent you 3 pages of wiring diagrams via email if you do not already have them. I would post them on here but I do not know how to post a Pdf file.(admin help?) Others may be able to help further if I could post them. Let us know how it goes. Jeff
