One on/off switch for the house bank.
One on/off switch for the start bank.
One on/off switch to combine the two banks.
The combiner switches went bad and I had to replace it. Turned out I wired it back asswards.
Seems when the combine switch was off it was really on. And vice versa.
Thanks for the input.
I love you guy's
I made a living troubleshooting and repairing electronics and related equipment. Here is your original statement:
"When I start the boat. I have an issue with other electronics shutting down Like the GPS.
Just started doing this"
Here is your second statement:
"The combiner switches went bad and I had to replace it. Turned out I wired it back assward"
I learned long ago, if something was working OK and you did some work on the equipment and now it doesn't work OK, there's a good chance that your work caused the problem.
Or in your case, the electronics were working fine, you replaced the switch and they no longer were working fine. Go back and check your work.
