Re: Battery won't charge.

You have a short across the circuit. That’s why you don’t see the 13 volts when you have th charger hooked up but only when it is disconnected. Fuses don’t always blow with these 12 volt systems like you would think. Investigate your field wireing

Re: Box full of bad controllers

Thanks. I know Evolution 1 and 2 don’t match that’s why there is two separate wireing schematics for the boards in the diagnostics manual. I tried to use a evo 2 14 kw controller I took off on an existing evo 2 13 kw. And it wouldn’t work. . I think I’m finally starting to get it. Has to be the exac...

Re: Evolution controller warranty procedure and attachment

Some of the problem I think is I can’t open an account with Generac because I’m not a dealer. I’m getting second hand info. I do occasionally get on the sight. Basicly you I’m the one who has all the licenses an credentials . I’m not interested in becoming a dealer. I’m 62 and looking at retiring so...

Changing out coil on ATS

Changed out a pair of burnt coils for the first time also the board was fried. I think it was water damage. Was not too happy with the little square nuts that were hard to line up. And the mounting bracket that the screws go through makes it even harder. Seems they could find an easier way to mount ...

Re: Box full of bad controllers

Well I only have one question left. Is it possible to use a controller off another generator as long as it is the same style. Basically 3. Controllers to match up. All the controllers we have is the Evolution 2

Re: Box full of bad controllers

I tried sending one in and they rejected it because I didn’t fill out the form with the proper diagnostic info. The other boards were changed out by other techs. I was trying to figure out a way to bench test the board like Generac claims they are doing. If they are really testing the boards and fin...

Re: Magneto rpm signal

Well we know the AVR uses the power winding sense to increase or decrease current in the rotor field. I’m agreeing with you. As the engine fluctuates under load there has to be a corresponding signal to the stepper motor. That’s why I was posting posting test 60 tb.4-10 to check ignition signal. I t...

Re: Briggs ignition system

I always thought thr Generac ignition signal was used not only for a rpm display but to to also control governor speed. After reviewing the generator control theory I don’t see any thing about ignition signal. Hoping to get a comment from you on this subject. Thanks
