Does anyone have any advice? I have a twin 2014 mercruiser 8.2 502 HO motors. When I turn the key on the starboard motor I get nothing - no fuel pump noise, no relays clicking, on my vessel view Im getting whole bunch of codes popping up (start sequence aborted, critical low voltage, some helm codes also)
I had the same exact problem 6 weeks ago, I changed the Buss (cubic fuse) on the starter. All the codes went away, boat started and worked great.
Today I went out to start it, I was getting a click noise from the starter when I turn the key (the starboard manifold had a slight leak, the starter was getting salt water on it for a long period of time) I replaced the starter this afternoon. When I went to start it after replacing the starter I now have the same problem as 6 weeks ago. When I turn the key on the starboard motor I get nothing - no fuel pump noise, no relays clicking, on my vessel view Im getting whole bunch of codes popping up (start sequence aborted, critical low voltage, some helm codes also)

I really don't think the buss fuse on the starter blew out again, I think this issue is more involved.

Does anyone have any ideas? Im at a loss.. Thanks everyone

Check all your cables and connections. Do a voltage drop test.

Has water gotten is the cable hooked to the starter and corroded it under the insulation?

Will check thanks

First thing I would do is check ground cables, not just look at them but remove and clean ends and clear faults see what happens. Next would be check (+) voltages. Another very good diagnosis tool is "voltage drop test" just google that to learn more. Used it many times as a tech in the auto shop.

tbanks, I will get him there and remove and clean everything.

Hey I am having the same issue, did you ever figure it out?

BB 5 yr old thread.......I say he did or set it on fire...........

I’d hope so😂
