When did generator last run? Gas or LP fuel?

Ask Your Own Small Engine Question
Customer reply replied 1 year ago
Yea it cranks over fuel type did run last year tried to find wiring diagram for fuel pump
Technician: Curtis B., Technician replied 1 year ago

Gas I assume. Do you hear fuel pump running? If you remove gas line at carburetor, and turn on switch , is there fuel flowing to carburetor?

Customer reply replied 1 year ago
Fuel pump not operating no spark but there is power to solenoid to crank engine the solenoid small connector feeding the circuit board is hot but from board out there is nothing
Technician: Curtis B., Technician replied 1 year ago

Let me opt out, and see if we can get a generator guru , I'm an engine guy, and don't have the wiring diagram for the unit. I assume you have located fuses and they are all good. Sorry. Please do not reply to me, or it locks your question to me.

I need to know the actual model number of the genset. I can not help you without it.

Don't have that on hand motorhome is somewhere else don't have that on hand motor home is somewhere else does the circuit board feed the ignition and fuel pump
Technician: Hank F., Technician replied 1 year ago

That depends on the actual model number.

The newer ones are powered directly from the circuit board, but the older ones are not.

Ask Your Own Small Engine Question
Customer reply replied 1 year ago
Not sure on the year the motorhome is a 78 model Ford I believe it's an older one on the starter solenoid the small pole goes directly to the circuit board it's hot all the way to the board but yet the pump and the ignition will not fire fuses are fine is there any way to test the board
Technician: Hank F., Technician replied 1 year ago

I have to know the model number to know which board it has in it.

I can not help if I don't know exactly which model genset you have.

Technician: Hank F., Technician replied 12 months ago

That is an old unit.

That unit can have one of 3 different boards in it.

I need you to look at the board, and tell me how many plugs are on the board, and how many pins in each plug.

I know the plug on the right will have 6 positions, but it may only actually have 4 or 5 wires going to it.

It is the plug/plugs on the left that I need to know about.

Ask Your Own Small Engine Question
Customer reply replied 12 months ago
OK will have to look tomorrow power goes in nothing out does the board turn on fuel and spark
Technician: Hank F., Technician replied 12 months ago

The board runs the fuel pump directly, but runs the ignition indirectly. It powers the coil, but there are other components that actually create the spark.

Ask Your Own Small Engine Question
Customer reply replied 12 months ago
No power positive side coil
Technician: Hank F., Technician replied 12 months ago

If you are not getting 12V to the positive side of the coil while cranking the engine, It can be a bad connection at the board, a broken wire between the board and coil, or a bad board.

Customer reply replied 12 months ago
OK I'll give u wires in and out so u can tell me witch board I have
Technician: Hank F., Technician replied 12 months ago

I won't be able to tell you which board you have, unless you have the old board that has 2 plugs on the left side. You will have to get the number off the board itself.
