Loose, corroded, or worn/damaged harness pins or cable connections are the most common cause of voltage drop.  Start by checking the battery and main engine cable connections and work your way towards the engine and dash harness connectors.

What did you buy and do.....

Have any repairs or maintenance been done, or any accessories installed since the last time the boat operated normally?  A disconnect or improperly connected ground cable to the battery can cause very unusual electrical problems. 

When the start/stop button is pressed a ground signal is sent from the button to pin 14 (red/black wire) on the Viper2 controller.  The start request is then sent from the helm Viper2 controller to the engine ECM via the Controller Area Network (CAN).  There is a START/STOP data field that can be found on the Settings > System Diag screen on the small display.

A start request can also be sent from the emergency helm keyswitch by using system voltage from the switch all the way to the round engine harness adaptor plug pin 17/G (yellow/red wire) then to the engine ECM pin 86.

If the engine is not running during a start request, then the engine ECM sends a ground signal from pin 34 to energize the starter relay.  The relay sends system voltage to the small starter solenoid post to engage the solenoid and turn the starter for up to 11 seconds or until the engine is running.

That is a pretty fancy looking vertical display in the article pics.  Although that seems to be the way all the local car dealers are going now - big glass inside display "ramps"

Carvana has a few Spare Vertical Displays

I really would like a 2020 or 2021 VLX too.  I like the traditional bow, but will say that the 21 LX interior layout is very nice.  Just a little concerned the wider front affects the ski and surf performance.  I know someone who has the LX and is lukewarm on it.  It's pretty far away from me, otherwise I'd try it out.  Thus, I'm here asking you all.  Thanks for your replies!
