Help! 94 Sea Ray 440 Refueling Safety Cut-Out?

[John Burdon]

I have a new to me 94 Sea Ray 440 Sundancer. Her condition is a testament to how well she was built. She has the Cat 3116 diesels. I have refueled her twice now, and each time I finish fueling and try to restart the engines the ignition breaker trips on both sides not allowing them to start. If I wait for 10 minutes then everything operates normally. Note, this does no occur if I just stop the engines then restart them. Is there a designed safety cut out to prevent restarting immediately after refueling, or do I have a problem?

No.

I suspect you have a loose connection on one of the 2 engine mounted solenoids. You can also try using the emergency start switch to cross feed the battery blanks so you have all 4 batteries doing the starting.

I think you are correct on the fuel solenoids. I didn’t think solenoids would fail gradually. It appears as they cool off (10 mins as noted in my post) they work again.
I am sure it is not the batteries.
I will check out the solenoids and post the results.
Thanks!
