  • rewire correct switch

    Posted by Marius on January 17, 2015 at 8:02 am

    It is time to take care of the generator start panel.

    The previous owner hacked the switch portion and had probably trouble with the stop (down) portion of the switch. Instead of getting a new double pole momentary switch like (I believe) the original should be, he had a single pole momentary switch for the start and added a separate button for the stop function.

    Now…I do not know yet if this has to do with why the inside Start/Stop switches for the Generator do not Start the Generator anymore ( but will stop it for some weird reason) but I should fix the outside part first. Correct ?

    I have the corrrect switch and would like to wire it.

    Looked through what I have for the Kohler 20kw in manuals and there is no wiring diagram. I opened the panel with the switch and I see a few black wires, unmarked. I have to sort it out.

    Can somebody with a Liberty- late 90’s- and Kohler take a picture of the wiring inside of the outside control panel in the converter compartment ? Or some advice as to how to restore the wiring correctly.

    Thank you.

    BTW, the Watchdog start system seems to be dead but I won’t jump to that conclusion until I restore the button wiring and then attack the Battery Watchdog.

    Any help, much appreciated.

    You still want this photo? I assume you’re talking about the upper of the 2 boxes in the inverter bay?

    Yes please. Correct, the inside of the upper box , inverter bay, to figure out the correct wiring of the switch to start the generator.

    Much appreciated.

    Thank you

    Still looking for some diagram or how to wire the bi-polar switch in a liberty gen start panel in the Inverter compartment.

    Thanks

    before i found this site i only had the personal cell numbers to the only two men that Liberty has in there service dept that can answer anything. they know every wire and the reason somthing is wrong.. the first thing i did when i got started was trade some tiny fuse in the watchdog then things started working. they were always nice to me.

    Marius: Do you still need help? It was 28 degrees here today, good for outdoor pictures. Tomorrow and next week in single digits and teens. Did you get a picture yet?

    Marius,

    I have not had issues beyond having to reset the Watchdog, but if my understanding is correct Liberty has their generator start without the Watchdog a manual operation using the switches on the generator itself, essentially bypassing their system entirely.

    I can’t remember if your coach is 12 or 24 volt, but if it is a 24 volt, I think your A-B PLCs are also a part of the system when the Watchdog is functioning so without specific wiring diagrams you might still have a problem correcting the wiring to restore the generator start/stop function.

    Bear in mind the Watchdog not only is part of the start/stop function, it is the device that protects the generator from damage due to overheating, low oil pressure etc and those protections are lost when it is bypassed.

    Thank you Jon.

    You have seen my coach in the air at Jeff’s place a couple of weeks ago when we pulled all that water and oil out of my air tanks….You were there to talk with Jeff about the training sessions.

    Jeff has tested the Watchdog module, has it working properly and now is addressing the Start/Stop switch outside as well as the correct wiring for the inside switches ( driver panel and rear lounge).

    I decided to let Jeff sort this issue out because I believe that he is very good with electronics and along with the rest of the things I wanted to get addressed, the choice to take the coach to him and leave it there for 6 weeks was the most feasible approach…..11 hrs drive away from where I live but I think the right thing to do.

    I can tell you all that read these posts that I have dealt with a few repair/upgrade shops in my life and I happen to operate a business that upgrades coaches of the “plastic” kind……When it came to this Prevost, after doing my research, meeting him, going over the coach side by side, I believe that Jeff is the professional that I want working on my rig and has the tools to get the job done.

    I will have to wait and see how much I still like him when he presents me with the final bill ……

    You could not have chosen a better and nicer guy to partner with for the “Know your Prevost” seminars.

    We are very pleased with Jeff and all he has done for our members.

    He answers questions on the forum, I know he is a much lower cost alternative to Prevost on chassis work such as air bag replacement, and for our seminars we are getting not only the use of his shop, the lifts, and the large area for parking, we are able to plug into his knowledge based on years of experience.

    While our seminars are not going to do any more than brush against some converter information we also know Jeff will be available during breaks and after sessions to answer some if not most converter specific questions not covered in the seminars. It is a great deal for all of us.

    Marius, while it is never fun writing those checks, I can say that I mind it a whole lot less at Jeffs place. Geo.
