I appreciate all the advice. Had some nicer weather (finally) so I
drove down to the boat this morning. Couple hours of mucking around and
I got it sorted.
I was able to get the engine to crank over when I hot wired the
solenoid, and the multimeter was showing power to the starter/solenoid.
That left me thinking something was wrong in my panel - corroded looking
plugs but no response from cleaning a few or from wiggling contacts around.
Brief call to mechanic and he suggested the fuse box on top of the
engine would be the culprit (given the blower was not running either).
I had already checked fuses and resistance was OK - but after some
digging I found the outgoing wire was badly corroded and had a break
hidden up underneath where it went into the wiring harness (variable
voltage readings when I moved wire around).
Quick fix was to cut the wire - clean up the ends and splice it back
together with a butt connector - engine fired right up!
Thanks for the help

Thanks for all the feedback.
I'll me digging out my multimeter and heading down to the boat this
weekend. I now realize that I don't think the engine vent fan turned
on when I turned the key (my lights on the panel are rather
intermittent and my engine overheat buzzer has never worked, plus the
tach is intermittent -- so good chance that the wiring harness is the
culprit).
I'll check the fuses on the engine and see if I can find the ground
wires.
No glow plug to deal with.
I've also been advised to check the "neutral kill swtich" (stops you
from starting engine in gear) and the "oil pressure kill switch" - not
sure where those are so I'll have to look at the engine manual.
I'll see what I find and come back with more details if it's not working
Thanks,
Mark

Stopped by the boat today planning to get prep'd for some work that
need to get done.
Figured I should kick the engine over just to make sure everything
was running smoothly. Unfortunately I got nothing (absolutely
nothing) from turning the key.
Batteries seem fine. Able to run radio - and no visible dip in power
to the radio when trying to turn over the engine.
I had a similar experience a year ago after running the diesel for a
few hours - wind came up and we sailed for a bit, but then couldn't
re-start. That day I easily found a loose wire (clearly it had
shaken loose with the engine running for a long period) off a clip on
the starter solenoid (?).
That was my first check today - but it was attached. Pulled it off
to clean contact but no effect.
I figure there are 3 possibilities
1- ignition key failure - no signal to the starter to kick over
2- starter/solenoid failure - I doubt this as I'd expect some type of
noise or power dip indicating that something was seized
3- electrical connection failure - I can see a large wire leading to
what I presume is the solenoid, plus a couple of smaller wires
connected as well. Nothing obviously disconnected
I need to head back down to the boat with a voltage meter - try to
figure out what is going on and hopefully find an easy fix!
Any advice is appreciated. I presume is the key is working them I'd
get a voltage spike at the solenoid when the key is turned. If
nothing then it suggests either 1 or 3. Where should I see that?
I expect I'll pull the panel and check the contacts behind the
ignition key - maybe try hot-wiring it if I can figure out which
wires are needed
Should I use automotive jumper cables to bypass the starter and try
to spin the starter/solenoid directly?
The engine is a Volvo 2002 18HP
Thanks in advance for the advice,
Mark
