i finally got my boat back - but it isn't running.

Bad news - the mechanic basically left it in the back for 6 months and never completed anything. started a lot of projects,
but none are complete. I am trying to figure out the wiring now.

the smart craft gauge will not display anything - yet I have power to turn the engine over and the analog guages move while cranking. voltmeter shows 12V at the helm. battery has 13.2 V and full charge.

can anyone tell me what these three wires are supposed to be connected to?

black, orange with faint stripe, and brown - all with eyelets - implies to me they should be screwed down to something.

thanks

ok - I wrapped them in electrical tape for now to make sure they weren't grounding against the block..

smart craft gauge still does not work - I bought the SC1000 assuming I need it for this 2003 boat that has all Beede guages from the factory.

Can you point me at some diagnostics documentation?

thanks

I'll open a separate thread about freshwater cooled vs seawater system..

Thanks for your help!
