I have the mentioned generator scheduled weekly to run for 15 minutes. Did not turn on last weekend. Red light was on side panel. RPM sensor was on the screen. Battery was 7 1/2 years old. Replaced it. Turned on manually with no problem. Five days later attempted to start it. Would not start. Took battery out to charge despite being new. Was charged. When put back in generator started manually. Afterwords would not start. No clicking, no sounds - nothing. This has been the case each time it would not start. Each morning I attempt to start it manually and it starts running well. Afterwards nothing. Screen says “cranking” then reverts to “RPM sensor”. Any suggestions, comments? Thank you for your time.

How corroded are the battery cables?  Clean them and use good conductive grease.

I'll take a stab at it similar problem and I found out that the control board was at fault no display showing I had the red light too.

Very clean. Has been well maintained. Just scheduled test and it started running through test cycle. Started manually several minutes later and started right up. Head scratcher!!

odd. where i see this in the field its almost always cable related. i had one unit that i tightened all the ground points and tightened connectors down as tight as i could and still no start, but when i went and hard twisted each connector the battery positive twisted when turned. could not tighten any more. cut off end and put on a replacement end. generator started fine.

Just attempted to start generator  manually. Silence while screen read “cranking attempt #1“ then “RPM sense loss”. Removed cables from battery, cleaned connectors and battery thoroughly. Still nothing. 20 minutes later I attempt to start manually and it starts perfectly. Strange that it will start at times and nothing at times.

Check the other ends of the cables, especially the ground cable.

Post the Sn please.  Sounds like the starter relay or solenoid.  If it doesn't turn over it will give the RPM sense loss.

Cables on both ends are tight. SN -E8827488 13038

Not the correct SN, Should be on the engine side of the firewall between the engine and the battery in the upper corner toward the front.

Thanks for clarifying where the correct SN is. 7849044

You need to check the start relay to see if battery voltage is going to the #56 wire when it is not cranking but should be.  Then check to see if you have battery voltage on the #16 wire to the starter at the relay if you don't the starter relay is bad if you do the starter is bad.  The old battery could have done damage to these components if it was low when it was trying to start.

Will do what you say. Waiting on retired electrician neighbor to help me out with this. Will let you know how things go. Thank you.

What would the cost of replacing either of these?

Problem fixed. Finally got to it. It was the starter relay. Replaced and running great. You guys are awesome. Thanks for your advice.
