Hello, thank you for requesting me.

What are the model and serial number of the genset?

Ask Your Own Small Engine Question
Customer reply replied 7 months ago
Kw 20. I don’t have access the the serial number right now.
Technician: Hank F., Technician replied 7 months ago

20 kW is a size rating, not a model number.

I an't do much if I don't know which model you have.

Technician: Hank F., Technician replied 7 months ago

I still need the serial number. I need both numbers.

Hank...I hope youre a Patriots fan!
I am waiting on your response. You now have the serial number (8408846) and model number (0062440) as soon as I hear your recommedations I will take action. Thanks again
Technician: Hank F., Technician replied 7 months ago

Nah, I don't like baseball.

I pulled your serial number, and found that there are no bulletins out on your unit.

Code 1505 is RPM Sense Lost. It means that the controller can not detect the engine cranking.

In your case, it is because it is not cranking, so the first thing we need to do is to have the battery tested.

Do not rely on a volt meter or battery charger to tell you if the battery is good. Even a bad battery can read fully charged with 12V, but not have enough ampacity to do any work.

If it turns out to not be the battery, let me know, and we will dig deeper.

I replaced the battery. Nothing changed.
Technician: Hank F., Technician replied 7 months ago

Ok.,

Remove the panel over the controller.

Underneath, you will see a relay with 4 wires attached to it.

Locate wire 56 at this relay, and connect a DC voltmeter across wire 56 and ground.

Set the gen switch to MANUAL.

Is there 12V present on wire 56?

Did you test this yet?

Actually I brought in a Generac technician. The unit had flooded and there is saltwater in the oil. This thing is cooked.
Technician: Hank F., Technician replied 7 months ago

You didn't say anything about the unit having been flooded. That was critical need-to-know information.
