Went fishing this afternoon and had an issue I never had.
After playing with my new terrova and down image transducer, I had a notice come up on the bird saying low voltage. I went and tried the motor and it cranked fine. Went back to fishing and it happened again. This time motor turned over and over but would not start. Then wouldn't turn over at all

Batteries were all fully charged. 1 is for cranking and electronics and live well ( it has timer). The other 2 are for 24 v terrova.
Just curious if y'all experts think the bird could have used that much voltage ?

Any and all suggestions are welcomed.
