My unit runs through a power switch same as my old g2 mega did and I never had problems before this.
For reference I have a 1775 Lund impact and the power has always run through the switch board then to the cranking battery and I never had a problem with it for 5 years upgraded to a 12” because bad eyes helps me see the screen a little better.
When upgraded to this 12” unit I also put in a new epoch lithium battery and switch all the electronics over to the lithium.
Im going through connections and checking things out so far no issues that jump out.
It was so weird I’m on the water units on for about ten minutes and I go over a school of crappie I’m guessing mark the spot and then I’m saving my favorite setups to the quick buttons and the screen goes black but the unit still is on and has sound. If I push a button it responded with sound. I have no idea why this happened first time on the water and I didn’t run the unit for but a few seconds in the garage to verify everything was working and connected.
After leaving the lake which is about a 25 minute drive from home I try it again to see what I can do and it fires right up screen works fine no issues. So I’m wondering if to test it I could put the transducer in a bucket of water and let it run for 10 minutes and see what happens.
Appreciate the post.
