Mine is a 12v circuit. Have not de-winterized yet (probably 3 or 4 wks) to check voltage at the terminals. There are 3 terminals that operate a center tapped coil that when voltage across center to one side or other moves rod in or out to allow or stop fuel flow. I don't remember if my start and stop switches complete the circuit to ground or apply 12v. There might also be a relay in my wiring box mounted on the end of the engine.

I got the cat tech back down and he replaced the stop solenoid. Once removed we checked the operation. Pretty obvious it was sticking. It's been working perfect since. I also learned that to manually shutdown using button on solenoid takes a heck of a lot more effort than I thought it would. I'm winterized now and won't be checking the voltmeter issue until spring. With heater on about 9, after 12. During normal operation electric panel and dash guage are about 2 v difference.

Volt meters are same, I am looking into the overall voltage now as the starboard alternator is not putting out as much as it should. Using the cross over increases voltage and after a few min. Selinoid will work ?
After starting preheat units kick in voltage goes - 8 ,after pre heat voltage only gets to +6 with cross over on voltage goes to +12 could be alternator ?

I have had this problem for several seasons when first starting boat in the spring. Once it finally shuts down I can go months without any issue. Pushing the stop button on solenoid doesn't seem to have any effect. Recent service seems to have caused the recurrence of the issue much more often. I'm thinking loose or partial connection. Voltmeter seems to also be affected. Does your voltmeter on the dash agree with the one on your panel?

I can't get to the selonoid when running, to hot. Area is very restrictive. Have noticed that with battery in parraelle volt meters increase charge and will shut down in few minuets. Since starboard alternator charges cranking, port house believe it may be a current issue with starboard alternator ?

Ongoing issue port engine at times will not shut down. Have checked relay and fuel selinoid both appear ok. When at idle amp is +4 depressing stop increases to +6 when released drops to -6 and returns to +4
If I increase RPM and turn on crossover battery meter increases to +12 / 14 and motor will shut down after a few minuets . Cat is a year 2000 with 700 hrs. Port engine charges house Starbord charges cranking. Both are wired with preheat that turns off at 120F. Both engines run at 180F. Problem occurs mostly on short runs.
Apreciate any advise. Thank you
