Look at this wire diagram. There is nothing between the S10-1 and the K2-X1. So if it will not turn over with the S10, Check S10-2 for 24 VDC. If nothing is there, Check CR1. see if you have 24 VDC on the input side, and output side. If not CR1 is bad.

were do i check voltage on s 10 , cr1 no voltage in or out checked another 803 i have that runs can't see anything deferent . Thanks for your patince need all help i can get

Look at S10. There are three wires on it. In the diagram above it is shown in the OFF position. It is a three position switch. When you want to crank the engine over, you turn the switch to the crank position. That makes the contact between position 2 & 1 on the switch. Power comes from position 2, through position 1 on the switch, causing the K2, (Starter Relay) to close. That turns the starter over. So, back to S10. Position 2 should have the wire # 120A hooked to it. Using a multimeter, measure from a good ground, to wire # 120A. Do you have 24 VDC there?

Is this gen set new to you?
Have you ever seen it run right?
Can you use a multimeter?
Can you read and follow the wire diagram?

yes its new to me. Yes i can read the dia and use a multi not something i do often but i can manage , the dead crank worked for a few times, it will start by jumping the starter motor and holding the fuel solenoid run,s fine makes power. It got dark last nite will try agine today Im in san diego cal big time deff Thanks Mike

Batteries dead?

new bats . relays click I can make it run by jumping the starter motor and pulling the fuel solenoid, Dead crank worked a fem times Now nothing . must be a wiring prob

In message #2 I asked that question, and his reply was yes, they are charged. Lets see what comes of the S10-2 check.
