Maiden trip

[jorgefife]

Finally, after 1 year, 2 months and 12 days I went sailing today!
Up and down the chanel in Clear Lake, trying hard not to hit bottom ( as Sam said on his profile) and avoiding all the crab traps strewn everywhere
What a day! All tanned and flushed like a boy on his first date.
Boat handled admirably(I will put it for sure for everyone to see), and no problems
Except perhaps that I have a massive jib, which made me skate on the water with no control on the rudder
But that is another story: I think I have the jib that Larry Edison used on his boat when he won the cup
But I need some help here, and before I try and understand the Manual, someone out there may short circuit my research by going right to the point
Here it goes: engine sounds great and fires right up, but I was told it is supposed to sound an alarm momentarily, to0 remind you to look down there if should be a problem, and it is supposed to stop the alarm a few seconds after.
I have no such alarm warning; where do I look?
On the control panel where the start/cut-out switch is?
Another light (voltage) and one other come on, but no alarm
Anyone can suggest whewre do I look?
The engine is a Yanmar 2GM
Thanks
I am still all revved up, will take something strong, like aguardente (portuguese equivalent to fire water) to quiet down

Congratulations

Jorge,

Got the same boat so here goes....when you put the ignition key in and turn it to the right, you should hear a buzzer. Press the start button, the engine should fire and the buzzer will stop.
If it is like mine, it doesn't have any gauges, just idiot lights.
One is oil pressure, one is temp. If either gets too high, or too low for the oil pressure the buzzer will sound.
Once you pull the engine stop cable, the buzzer will sound again until the key is turned off. That's it.

Congratulations on a great first day.

As I said, I have the exact same boat so if you have any questions, let me know.

Normally if one of the lights comes on you should hear the buzzer, the two are supposed to be connected togheter, maybe you have a problem with the buzzer?. The buzzer when you turn the ignition key on if from the oil pressure switch, the buzzer comes off when you start the engine because pressure builds up. I would start by looking at how messy the wires are behind the panel and in the engine bay, maybe someone improvised down there...

Dave,
Thanks for responding
I bnought a key on e-bay because a neighbor has a key on his 1979 Hunter 33, but then I discover that my boat has a push button to stary, not a key
You pull out a lever, 2 lights come up on the panel, push the button and the engine fires up right away.

Mathrin2: Thanks also; I will look at the cables also, but it seems that the key trick is what makes the buzzer go; maybe someone improvised by installing the lever you pull out, and then the push button.
It may not be original, but I would very much like to hear some kind of alrm!
In my high spirited mood yesterday I could have been sailing right down to the botton of the lake and still be thrilled!
Will take a picture and post here
Thank you again

Jorge,

I'm thinking that there has been a modification to the panel. Maybe the previous owner kept losing the keys....

You should be able to access the back of the panel from the starboard cockpit locker... are there any wires loose, off etc?

Humm, I don't know if you have the same kind of panel that I have, but if you do, someone really messed with the wires. On yanmar panels, the chrome lever you probably pull to start your engine is normally used to open/close the tach light, and is in no way designed for the kind of amps necessary to drive the solenoid switch on your starter.

 

[Mathurin]

Btw the easiest way to access the back of the panel is to remove the 4 screws holding it in place. There should be enough wire to drop it face down on the cockpit floor.

Hello there
It's me again!
Breaking wind 2: yes, there is no problem accessing the back of the panel: I believe 4 screws remove it; I will check for loose wires

Mathrin: I am not at the boat, but the buttons, as far as I can remember, are positioned as follows:
far right: a lever pulls out, and the panel lights up with 2 different ones, I forgot what it shows, one I think looks like a strike of lightning
then to the left of it there is a black rubber switch that goes up or down, and to my knowledge, does nothing
To the left of it, there is a push button that you press when the first lever is pulled out: motor fires right away
And lastly, to the far left, there is a lever that you pull to cut off the engine
I suspect it has been modified, but it looks like it was always there
I will go there again Sunday and will send a picture
But I will check for any loose wires, I did not do that

this may be of some help:
http://www.motoren.ath.cx/
go to the web page, chose yanmar on the left.
chose the third link, the one that says :
1GM10-2GMFL-3GMDL(PDF file 1.5 MB)
have a look at page 14-15, if you have basic notions in electricity you shold understand.
thats the most info you are gonna get.
You could probably download the first link too, it's the shop manual and it can come in handy (but I aven't had a look at it, it 60mb and my engine is a 3qm30)

 

[Mathurin]

Also take a look at page 28 of the same doc

Will Do
Thanks

I have the same panel you describe on my H27, Sometimes the buzzer takes a second or 2 to buzz...sometimes its immediate...I am not sure if this is a problem or not...it seems to function fine.

Jorge:

If the tips/suggestions already posted still don't get your alarm buzzer going, I recently dug into my Yanmar wiring just to assure myself that the alarm circuits were working properly. So I have a little insight to convey. Print out the Yanmar wiring diagram on page 15 (= manual page # 10-3) of the pdf File that Mathurin2 directed you to. This will help you identify the wires both at the instrument panel and at the engine and the various alarm circuits. The below is a summary of the steps from my Yanmar manual with my interpretion of the sequences added. First, check that the engine 12V fuse is not blown (unlikely since other things are working for you). On my QM model Yanmar, the fuse block in mounted on the engine, not far from the starter motor. At the engine, disconnect the wire from the oil pressure warning switch. Turn the key to the on position, but don't start the engine. This activates the +12v to the alarm buzzer (and everything else on the panel including the push button starter motor switch). Touch the fitting of the oil pressure switch wire to the side of the oil pressure switch, or to any clean bare metal part of the engine (i.e. touch the wire to ground thus completing the circuit to the buzzer). If the alarm sounds, then you most likley have a defective oil pressure switch. Also note that the oil pressure light on the panel goes on. If the alarm doesn't sound then the wiring isn't completing the circuit to the alarm buzzer. Next step is again at the engine, disconnect the wire from the high temp alarm switch. Touch to the side of the switch (or any other ground). If the alarm goes off, then you most likely have a break or bad connection in the oil alarm wiring. If the alarm doesn't go off, then you really will need to check all the panel wiring for continuity. Something is amiss -- maybe the
+12V isn't getting to the alarm buzzer. The instrument panel doesn't have any solid state parts, resistors, capacitors, etc. that can fail. Just 12V, simple switches, wires, lamps and the alarm buzzer. Oh and the tach.
