"Here's the specifics:
Boat: 1982 Bayliner 19' Capri
Engine: Volvo AQ125A
Stern Drive: Volvo Penta 270
As I've said before, it's a tired old engine. After draining the oil from the stern drive (which came out with the consistency and color of Elmer's Glue), the drive quit whining and the boat was running great. I used gasket maker to seal up the top of the stern drive (the old gasket was shot and was letting tons of water into the drive).
I've always told my brother to check the oil before he takes it out, as the engine consumes quite a bit of oil when it's run (I'd say a quart every 6 hours of running time). Well, as usual, he doesn't heed my advice.
He had the boat out on the lake and had been running at full throttle for more than a half hour (this is after 2-3 hours of boating done earlier in the day). Suddenly, the boat dropped about 1000 RPM and he backed the throttle down to neutral where the engine promptly died. He tried to fire it back up and cranked it for a long time (he says spent almost five minutes cranking it, hope he gave the starter breaks during that 5 minutes), but had no luck.
He called me and I asked him what the temp gauge said. After the boat had been sitting for 10 minutes, the temp gauge was still reading around 215º. I know the impeller is fine and that the cooling system works. I had him check the oil and he said it wasn't even registering on the dip stick.
After getting towed in by a sheriff (boy do they have some impressive boats! Ben was promptly written a ticket for some violation as well...), I took a look at the boat. We put in around 2.5 quarts of oil to bring the level back up between the lines on the dipstick.
However, when I turned the ignition to on, nothing registered. I jiggled around the ground cable where it connects to the engine and the gauges lit up. I tried to crank the engine and it turned for a few seconds, so it isn't seized and the starter is still working.
However, now I get absolutely nothing at the gauges. Whether the key is in the on position or the start position nothing happens. The only things that do work are the bilge pump and the blower.
I got out the multi-meter and started testing voltages at various points with the common probe attached to the engine:
Battery: 12.6 volts
Alternator: 12.6 volts
Starter: 12.6 volts
12 V feed to fuse block: 12.6 volts
All fuses in the fuse block have continuity
There is continuity through the main fuse near the flywheel of the engine. The terminals on (what I am guessing is) the ignition relay are fairly corroded. I'm thinking we might have a bad ignition relay, but with no wiring diagram, it's a bit hard to tell where all the wires go and what their purpose is.
Any tips or insights as how to fix this problem?"
