    Default Self Starting volvo penta Lagoon380

    Hello from Panama, Lagoon380-VP380 with VP D1-30, Stbd engine starts by itself..amazing..Anyone had this problem?.
    Actually I've seen this on 6 various Catamarans with Volvo Penta engines..
    I've jumped the y/r starter wire across the Cannon Plugs and changed the Starter relay..
    Now looking for possible problem areas within this particular Model...Any Takers? Thanks, CM

    I've registered with Multihulls4us to find out more about Lagoon catamarans and yours was the first post I read. I think I might be able to help because the same thing happened to me. I'm afraid don't bring good news.


    I have a monohull with the D2-55 engine. The problem was entirely the failure of the relay box, literally a black box, on the side of the engine. It appears to contain a fuse, some relays and other assorted electronics. Mine couldn't be repaired by a marine electronics business so I had to replace it. The cost was in the order of US$600! On the positive side it appeared to be a well stocked item in the local VP dealer. (I was visiting USA at the time). There is a VP dealer on Panama on Isla Flamenco.


    The second time I suffered the same failure I removed the entire wiring harness and reverted the engine to a basic system for starting, stopping and warning sensors. You could also consider this option which is basic stuff for marine diesel mechanics.


    Although this isn't what you wanted to read, I hope it is at least useful in your search for a solution.

    Welcome, and what a simple and obvious temporary solution that would not have occured to me.

    Cheers

    Unfortunately, replacing a wiring loom on a 38 Lagoon is no simple feat.And the Black Box is nothing more than 2 relays and bits. Your Marine Electronics Business is Selling and not fixxing.
    Okay, onwards and I'll post the fix when I finish it.......Ciao4now
