Default Help! No DC power on 2700 SCR

Hi,

I need help! I am unable to figure out why I lost all DC power (except to the bilge safety switch) after taking out the starter on a single screw 1996 Mericruiser 7.4 bravo 3.
My boat is a 1995 Maxum 2700 SCR

I REPLACED the battery selector with a new one being careful to go one wire at a time. Still nothing. Battery have a full charge on them. Next replaced the red 50amp DC button that is on the engine block. No luck for this Shenanigan!

Next, I have power before the switch to the trim tab solenoid. Not sure where to go next?

I had power before the boat mechanic removed the starter. After he took it out. No power at all. I thought it was because the starter was removed. I put the new starter in on the solenoid left post yellow, middle red large and right post the two other wires that were grouped together by the boat mechanic. Still no juice

Is there another button or switch I am missing.

Totally frustrated!
Dan Marina

Welcome aboard

Do you know how to use a volt meter? There is a 90 amp fuse on the starter soleniod that could be blown.

With a volt meter and the wiring diagram you need to start at the battery switch and work forward until the voltage is missing and you will have found the issue.

Thanks yes I know how to use a volt meter., no luck with the 90 amp fuse that was connected to the back of the trim tab solenoid. I will be replacing the solenoid next. Then I will be out of things to replace. Lol!

You checked the wrong fuse, I said the fuse on the “starter” soleniod.

The trim pump soleniod only provides power to the trim pump.
