94 275 pro xl aerator timer help

[dustmanion]

First off let me say hello as this is my first post here.

Now to business... i have a 94 275 pro xl my it runs the 2nd generation timer with the front mounted 2,4, and 6 min selector with the auto, off, and manual switches.

my port side runs fine on both auto and manual no problems what so ever

my starboard however only runs on manual.....

thats where i am stumped my boat only runs 1 timer which when checked with a voltmeter checks fine... 12(+) on red, (-) on black, and pulsed 12(+) on the other wire... the 2,4,6 min side of the timer also checks fine and you can feel and hear the relay click when turned on

so my questions are

how can 1 timer run both pumps individually?

if it is a fuse problem where would the fuse be located on my boat?

if it is a wiring problem will someone please explain how this dang thing is wired to both pumps and controls them individually?

....i did fine the sticky with the stratos wiring schematics but it was to no avail

thanks for the help the boat looks awfully sad being torn apart as it is right now
