Title says it all, just curious if anyone has any insight that my (not very mechanical) self hasn't come across.
Back story is was a totally fine, all normal running motor
as of last time I shut it off on Wednesday, ran totally normally the whole day (on and off a few times as we were day sailing
but in light winds and heavier currents so motor
sailing some). Came out to boat
site) on Friday, everything looked fine, did normal fluid checks all good, went to crank it and nothing happens... no click, no turnover of engine
Turn key to ignition everything sounds normal (low oil alarm
sounds because engine
isn't running, glow plug
switch works - big voltage drop as normal when hit glow plug
switch) but when turn to "start" just nothing, no click of solenoid, engine doesn't try to turnover, and there is no drop in voltage (like I would expect if starter was trying to run but couldn't).
Things I'm pretty sure are good:
+ plenty of battery
were at 12.5-12.6 volts when I tried to start, used a jump start battery
pack with no difference, we are now on a dock
(thanks BoatUS / TowBoatUS!) with shore power
and fully charged batts and still nothing, no crank at all.
+ I appear to get good voltage at the starter, 12.6, but haven't been able to test if that's there when key is twisted (on my own until tomorrow morning).
+ I don't think (but of course can't say for sure) that it's something like a hydrolocked cylinder / water
in the fuel
/ something that makes the engine itself not want to run because I would think those things would allow the engine to crank but not catch, and it just won't crank at all
Things I've tried:
+ jump starter / etc above to make sure I have the juice, batteries
are definitely good, of course could be wiring
between batts and starter
+ tried, as best I could figure, to jump the ignition switch... three terminals on the back of ignition switch, one is 12v in from battery, one goes out to all the things that turn on when you turn the key to ignition, I assume third goes to solenoid, so I jumped power from 12v+ to the solenoid out and no change
+ banged on the starter to see if it would disengage / knock some junk off the brushes
, no joy
+ someone mentioned an ignition interlock (won't start unless in neutral), I am pretty sure I don't have one but even so tried moving gear
shift into forward and reverse slowly while turning key, nothing.
Things I wish I knew / did:
+ can't find any terminals that look like a solenoid, I'm guessing it's internal to the starter? so I banged around on the starter with a hammer like I was trying to hit the starter and/or hit the solenoid, but I don't have two fat terminals that I could jump with a big screwdriver or something... wish I did because with no click sound I highly suspect my solenoid
+ turn the crank by hand... honestly not sure if this is doable on this engine, but there's the end of the crank there maybe I could try that (to dislodge a stuck starter for example) but I don't have a socket that will fit over the crank shaft and if I did not sure if I have a long enough breaker bar to twist a 1.5 liter diesel
by hand anyway?
I have mechanic
coming Monday morning and hope he can help to sort it, putting crimp in our (always too short) vacation
plans, although I realize things could have been much worse (we got towed in for free on our plan, and while we're not in our slip because they couldn't get us in there under tow we are on the guest dock
, plugged in, all is well in the short term).
If there are any thoughts I'd be interested to hear, I personally feel like it's a solenoid (because I hear nothing when I turn the key and there's no voltage drop like I'd suspect with a frozen up starter) but I can't find it to jump it to test it, any other ideas appreciated.
As always (when I post these "why won't this work" posts) thanks in advance,
