[RE-wrenches] GENERAC EcoGen 6kw problem

[David Palumbo]

I am troubleshooting a 6kw EcoGen LP gas generator in my neighborhood that starts quickly 
• but immediately shuts down with an “Under Voltage” shutdown alarm
• I can clear shutdown alarm and restart with same result. I tried this a few times with same result. One of the start attempts included a back fire before shutting down.
• Generator was recently run successfully for a few hours during a cold snap. Started after several attempts at -10 F.
• According to the EcoGen manual this Under Voltage alarm is triggered “If the generator voltage falls below 85% of nominal for more than 15 seconds”.  This definitely isn’t happening as the generator starts as usual but shuts down within one or two seconds.
I will check for fouled spark plugs tomorrow. Anything else that might be the problem?
