I have had more than one or two Cannabis errors. But not on a Generac, and things always cleared after a few hours.

The physical link is broken ignition module fails or reset the Nexus controller fails or reset
having the battery chargers 120 volt AC connected without a battery installed
a blown 10 amp ignition module fuse
a blown 25 amp system fuse

Checked both fuses. Both are good.

Same problem. First call tech support said replace charger based on tests. Second call replace controller based on tests. Any other options?

Not the Installer

Never assume nothing! Installer did not enter V Codes. Unit did not know what it was supposed to do so did nothing!

One of the problems with start up calls from other installers, you don't know what they did?

Again, Thanks for the response!:no:

I've only worked on one liquid cooled unit so far. I assumed that these came set up with those entered from the factory. Where it came into play was when you replaced the controller. Not the correct?

I am not sure what he is referencing. Unless he is talking about the activation code.

Must be. That was done on mine. Programmed and after I was don't the error occurred. Won't clear. Tomorrow will change parts. Lol

The nexus panel has a set of parameters that deal with voltage, phase, engine size, etc, that are entered when you replace the controller so the controller knows what it is operating.

Up and running, thanks!

Haven't been in a forum for a couple of years, but it is nice to get back online and in touch. The new control panel we installed was not shipped with the V code info, period, so we were hanging out in the wind , and really wanted to get this unit up and running. Thanks again!:thumbsup:

Long Story

Yours was a replacement?
Been installing Generacs since 1997.

Mostly install and service my own clients.

Started getting online referrals.

First call on a new unit not working, my tech suspected a solenoid, but under warranty reviewed with tech support, they recommended we replace one part then the control panel, then the new panel which was shipped without the V code info, and we are now waiting on a new solenoid because the control panel is not the problem.

I am in a cabin watching eagles on the Mississippi trying to give my tech support online and on the phone. This whole process is very atypical, usually it's one shot and done.

Definitely learning a lot on this one.

Again, I appreciate the online support!
