Malibu Vtx 20 2021 - When Battery on, boat starts by itself!!!


Recommended Posts

Hi,

We have a Malibu VTX 20 2021.

Since yesterday, when we open the battery switch the boat the starts automatically (by itself!).

when we shutoff the boat with the power button, it makes a cracking noice behind the boat, the sport dash flashes and then the boat restart automatically by itself! The only way to shutoff the boat is by turning the battery off…

Have you ever experienced this?

Anyone know what it could be?

Thanks!

Has anything been done to the boat since the last time it worked normally?  Like battery replacement, repairs, maintenance, or accessories added?

New feature to encourage use? 😁

seriously, though. I suspect you have a bad relay on the MCB.

I would check the battery connections and the main engine ground cable connections on the port side engine bell housing stud.  For multiple systems to be affected by a cross circuit I would either look for a disconnect ground creating a "reversed" DC circuit, or I would look for very severe wiring damage from a dead short or fire.
