Hello!
This is my first post so here goes:
I have a 1990 35lightning,it has three breakers on the starboard side of the disconnect switch and two on the port side of the disconnect.What do these breakers protect?
Also does the disconnect switch on the starboard,select which alternator to use and the port disconnect switch select which battery?
Any input would be appreciated.
Thanks

I assume when you say disconnect switch you mean battery switch? If so I would think the breakers would be for 1 each for the trim pump motors and 1 each for the drive pump motors.

As 35Lightning said, they should be for the Trim and Tab pumps. I don’t know what the extra one is for, unless it’s for the bolster(s).

Funny story:
I was leaving the Party Cove at LOTO over a holiday weekend, and saw a Fountain (42 Lightning if I’m remembering correctly) who was also leaving. One drive was down, the other trimmed all the way up. I pointed it out to him, at which time he said that he new, and seemed disgusted by it, the boat looked to be brand new. I yelled “Look under the back seat for the breakers”. They soon found it, and the trim motor started working. He was so grateful. I think that we saved his holiday weekend.
