Question about Miller 907068 MILLER TRAILBLAZER PRO 350D KUBOTA DH905

No power coming out of leads?

I think i''ve blown the main circuit board on this unit.The one with the dials. I've still got power to the 110 but it sure makes the grinders wind out. There is only 3 boards And am hoping it's only the one burnt out.. Any suggestions on where to buy the boards cheap, or better yet if i can send this board somewhere to get looked over and fixed? Thanks

have the voltage regulator system checked
in the regulator the voltage controls the amperage allowed and it that unit is not working properly then there will be no current out put
that regulator could be part of the control board for the main ac out put and may have developed a fault in the section for 12 volts on the board
there is a limit on the charge rate for the battery and if it is exceed it may have damaged that circuit or possible blown a fuse in the amperage circuit

I have a generac ix2000 and has an overload light on with no AC power out. what do i need to check?

When you have a generator with a inverter in it you have to be careful of overloads an static electricity. More than likely one or more otf the MOSFETs has blown. An inverter is really a switching supply. Not very hard to replace parts but if you have spme skill with electronics take it apart an give it a go. If transistors have not blown you may find a blown fuse inside on circuit board. You will never find a schematic for any of these units. They are protected because the dealers pay to much for selling rights you cant hardly get them. But i would take it apart an see what you have. Or find a good electronics guy an ask him to check it

Generator engine running but voltage is half of regular 110 volts

With the generator SHUT OFF - and NOT RUNNING, open up the covers and make sure all the electrical wires are connected. It sounds like one of the leads from the alternator has come loose.

Do I need a main breaker in front of a manual transfer switch

I'll assume you are isolating the main breaker that carries in current from the pole (this is called a service disconnecting means). By the term "main breaker" I'm assuming you are referring to a feeder disconnect; that is to protect the generator from over-current.
Under these assumptions, no, the generator has a circuit breaker capable of interrupting the circuit leading to the transfer switch. Under these conditions, you could view the genset's breaker as a "main".

Generator running but no powerout put

I would check the fuses to see if you've blown any of them. Make sure to shut the generator off and unplug all the devices from it before testing. If one of the fuses are blown, replace it with one you're not using and plug fewer things into the generator.

I have a 10 KW Generac Guardian Stand By withe a prwired EZ transfer swithc. Everything works except the 12 volts battery charger. What could be the problem. Only have three weeks innstalled.

Your generator is equipped with a battery trickle
charger that is active when your unit is set up for
automatic operation. The trickle charger is
designed to help extend the life of your battery by
maintaining the battery when the unit is
not running.
you will need to review which circuit bord controls this and have that board replaced or serviced some of these gen heads have this built in and it will be the rectifier in the gen it self it will be a black 1x1x3/8 inch with a mounting hole in the center and 4 lug post for the wires replace this and your issue should be solved but consult your dealer for witch unit you have as to a control board external or the built in rectifier hope this helps.
