I've put in new relay's thinking the same thing. I was thinking about the mag pick up but wanted some advice before moving forward. No fault lights.This sounds like you need to look at the relays in the control panel. Also, check your Mag pick up. If its not adjusted right, or damaged, the set goes straight to shut down.
Are you getting idiot lights?
Are you holding it in start position until it registers oil pressure? The engine won't remain running until it has oil pressure.I have an update to why the fuel cut off solenoid is missing. I pulled one off another unit to just test everything and it shuts the unit off before it can start. When starting, it will retract (as normal), then as soon as the starter disengages it extracts and shuts the unit down. Now, I can hold the solenoid back as I'm starting, when the starter disengages it tries to extract but if I hold it back for approximately 3 seconds after the starter disengages it will hold itself back as it should. From the TM it looks like the fuel cutoff solenoid uses 2 hot wires, 1 to retract the solenoid and the other to hold it in place. I traced down all the wires and made sure they were tight but still having the issue. Anyone else encountered this problem?
Oh yeah, this is not my first rodeo. LOL! No matter how long you hold it, the fuel solenoid will retract normally and will try to start but soon as the starter disengages the fuel cutoff will go back to the off position. It's weird, I'm going to perform the magnetic pickup adjustment tomorrow and run through the test procedure for the fuel cut off solenoid.Are you holding it in start position until it registers oil pressure? The engine won't remain running until it has oil pressure.
Test your input voltage to S1, before and during the startup. 20 volts is low. See if you are losing the voltage before the switch. Or in the switch. What kind of S1 is it?Tested the mag pick up and it was perfect. Then I used the TM to test the fuel solenoid and it's not holding correctly. But the solenoid worked correctly in another unit when I first got it, which was about a year ago. I've got to replace the motor so I've been pulling parts on it so I can not test anything else with that unit. Using the TM I tested all the way back to the S1 (master switch). When starting S1 sends voltage through number 3 lead on the back of S1 to hold the fuel solenoid back. Lead 3 also does a lot more but I tested voltage when starting and lead 3 goes down to 20 volts. Can anyone got out and test the number 3 connector on the master switch while cranking to let me know their voltage rating.
