fuse box 2800 scr

My Carbon Monoxide dectector is a 9v with an internal battery and is typically disconnected and sitting contently in a drawer. LOL!!!!! I do agree that there is a draw, though it seems to be anything. I've found great results by turning the fridge completely off. I used to see the volt meter drop and raise with no rhyme or reason. Volt meter would drop and temps guage would shoot up. Volts raise back up and temp. guage drops. This stopped when I started turning the fridge off while running. The same occurs with anything. If I hit hte horn, the volt meter drops. Trim IN/OUT volt meter drops. Tab Up/down, volt meter drops. windshield wiper, volt meter drops. and so on and so on. whn I say drops, i mean down to 10V.

since it happpen every time you activate something I'd start with the 80amp fuseible link on the top of the starters. this is what feeds your boat harness at the dash.

the gauge should never go below 12.7 volts, that what your 12 v battery is, any thing lower is a short.

the alternator rectifier bridge limits the max voltage to 14 to 16, and suppost to hold the amps down, but like sparking the battery cable, you can do some ark welding if your not careful.

If its fryed or melted like mine was, then its grounding out with every use. its way down low, so if its getting wet of splashed that a good ground out also.

any starter work is done by feel or laying on the engine with your head wedged in the well, plus you got to hold the light.....

my boat previous owner bought this one owner 2800, with a new engine and out drive (documented),had it surved in april 2010 for $800 bucks and sold it to me in October 2010.

I'm sure he took a loss, and I drove it home, never drove a boat before, nor tested this one, before waving goodbye.

Got 12 miles away and hit a sand bar....

first day, first sea tow.....

boat would not start again, towed to dock, by the same sea tow captain that had towed this same boat twise this summer for thrown belts......

I put the start on myself, upside down and backwards, but dropped the 80amp new fuseible link in the water...., got another, it was bad, got another.....

a week later, started back home again, got 4 miles from the dock, and the coasties flagged me down for a fire extinguse hunt....

got going again, and passed the same sea tow boat captain again.....

got home, then i had blidge pumps running, would not go off, batteries going dead, melted sea water pump housing, lose trim tab, toilet tank leak, carbon monxtide expired.

and my voltage gauge was doing what yours dose, pegging at 16 v.... the previous owner had a new gauge in the box for me....

so, it would sound bad expect, i got a boat $10k under market, with an new 740 garmin ($1800), and new engine and out drive... i called mercruser and they track the block number.

also, had a hurricane my first year of boating.......

point is, i see non mechincal inclinded boat owners, who primp and clean, with nice cd players and LED lights but don't thing to check fluids and hoses.

the real joke is the $800 boat survey, with pages and pages, pictures and pictures, but did not help the last guy....
