Unit is a Honeywell made by Generac model G0070600, ser # 3001383011. about 10 days ago noticed green and yellow indicator light was on. Controller said "check Battery" I assumed it was a routine check and hadn't got to it yet when after about 7 more days I noticed all 3 lights Green, Yellow and Red were on. When I looked at the controller it still said check battery and the LEDs on Off, Manual and Auto were all lit. None of the buttons on the controller would actually do anything although there was some buzzing (a relay?) when the escape or enter buttons were pressed. I turned off the breaker on the generator and pulled the 7.5 amp fuse to check the battery and with the negative cable disconnected the battery had 12.71 volts. The battery is a 2 year warranty battery and is about 3 1/2 years old, but I believe it is OK. I then opened the main disconnect breaker on the automatic transfer switch for 5 seconds and then re-closed it, reattached the battery cable, put the fuse back in and closed the breaker on the generator. All button leds on the controller are still lit and none of them will do any thing, but now the display is blank. It looks to me like the controller is bad. FYI In between the first yellow light and the yellow and red light situation we had an electrical storm that we think got our TV even with multiple surge protectors. If I replace the controller myself, how can I de-power it as with the breaker on the generator open the 7.5 amp fuse pulled and the battery disconnected the leds areDSC_1463.jpg  are still lit? I have done this type of repair (replace CBs) before on TVs and other devices. Is it likely it is just the controller or are there other surge sensitive components? Any help will be highly appreciated.

I would try a complete "power down" and re-boot the controller before you condemn it. The circuit breaker on the generator DOE'S NOT kill power coming into the generator - that is an output breaker. Disconnect the battery, remove the three fuses in the transfer switch marked N1, N2, and T1. Press each of the buttons on the controller one at a time to try to bleed any capacitors of residual energy. Re-connect the battery and put the fuses back in, see what you have.

When I have seen this in the past the controller had been hit by lightning.

I'll try the power down, I thought I'd have to pull those fuses to do that, I just wasn't sure. I'll post the results afterwards.

Pull the T1 fuse and disconnect battery ground wire.

I powered down - pulled the 7.5 amp fuse, disconnected battery ground wire, and pulled the three fuses in the transfer switch. I then pressed all the buttons on the controller a few times. I then powered back up. The led lights on the off, manual, and auto buttons were all still on but the display is now blank. None of the buttons seemed to do anything except maybe cause a relay to chatter or hum. So, I ordered a new controller and I will post the results after I install it. Thanks to everyone for the advice.

I installed the new controller. As I was going through setup the display kept getting fainter and fainter. I was able to finish setup but it was basically almost unreadable. I put the unit in manual and it started up fine so I put it back in Off after a minute. After it had been shut down for a few minutes I then put it in Auto and opened the main disconnect in the transfer switch. Per normal after about 5 sec the gen started and then after about 15 sec it transferred to the gen. Power was on in the house. At some point during this test I noticed the controller display was back to normal clairty/contrast. But, after I reclosed the main disconnect to restore utility power, again at some point it became very dim again. After consulting some forums I tried opening the main disconnect breaker then pulling T1 and N1 N2 fuses in the transfer switch, disconnecting the battery and removing the 7.5 amp fuse. I pressed all the buttons on the controller to bleed off power, then reconnected the battery, replaced the 7.5 amp fuse, then replaced the T1 N2 and N2 fuses and reclosed the main disconnect breaker. The display was still faint but maybe a little better so I could correct the time and recheck the setup. I put the generator in Auto, turned off the main power and the transfer switch switched to generator power per per normal. I never saw the display return to normal though. So, everything seems to work ok, the display is just very faint. I think the controller has a defect but I was told it is non returnable. Any comments?

I agree that there is some problem with the controller.  I would contact the seller and see about getting another one, I have never had an evo controller loose the display.

My guess.  Measure the voltage at the battery.  I think the battery charger is not working when on commercial power and as the battery voltage drops the display dims.

I also recommend checking voltage at the battery, and at N1, N2 and T1. It does sound strange and I have not seen that symptom.

is this controller really new? did you check the run hours on the new controller

I have a very similar issue. I have the Generac Ecogen 15kW generator. The advertising for this generator specifically states it is for off-grid use. 

I purchased the generator brand new in the crate from Generac. I installed it last week and upon hooking up the battery the LCD is blank and the warning lights next to auto, manual and off are lit up. 


I am not using N1 and N2 since the generator is being ran as a back up to my solar panels and lithium batteries. I have wire ran from the inverter to the E1, E2, neutral and ground. I also have the two wire start connected to my charge controller. 

These are the only wires I have hooked up at the moment. I plan on running 120v to the T1 to power the battery charger. I have been told the generator should start up on battery power alone and that the T1 is not needed to set up the controller. 

 I cannot find anywhere in the installation manual, install manual or on line that says what the issue might be when the three lights next to auto, manual and off are on. 

I have not been able to enter the activation code since the LCD is blank. Nothing has turned on except the lights. 

Any suggestions as to what may be the issue, or is it a bad controller out of the crate? One last thing, I have a jumper connecting both connections on the T23. I am not using a transfer switch, so should I leave the jumper as it came, or should I remove it?

Any help and/or suggestions would be greatly appreciated.

Generac warranty would cover a service tech looking at the unit and replacing controller at no cost to you, but i would suggest having the T1 power inplace so they cant say the problem is because T1 wire wasnt run.

Appreciate the advise. I will get that run tomorrow.

I had a customer call me a few months back that had a dead controller on a brand new generator....
had just completed running all lines. The controller display screen was actually cracked Down deep below the plastic view screen. Very odd how they even tested it at factory. Generac covered entire replacement at no cost to customer.

Good to know. I have read more and more about people having similar issues. It’s absolutely amazing that the quality control is lacking that much with a company that is a leader in the industry when it comes to standby generators. 

I am also surprised that a company like Generac does not have technical support that customers can speak with.

They dont want customers to work on the units. Then again, try calling GM with questions on your $76,000 diesel truck...... the warranty pays for factory trained tech to repair problem units. My own 22 kw gen is now 4 years old and not a single issue.

I tried most of the suggestions on this forum but the very faint display persisted. I installed another new controller and the display is now fine.

Generac has been great taking my calls and answering my emails.  I 100% agree with your statement, they don't want anyone but a factory trained tech working on it to restore it to OEM specs.  I will give them credit that when you do go down that road, they are rather supportive, more than GM is in my experience.  I have a 22kW air cooled and it has gone through a controller, cold weather kit, muffler and I think it was coils too.  I have also found that when you call the state's largest Generac dealer to get service, you won't always get a tech who is certified.  I'm thoroughly happy with Generac overall though.  Will buy a water cooled generator when my warranty expires.
