Re: Stus-List Hard starting 3GM 30

2017-12-07 Thread Hoyt, Mike via CnC-List 
Early and late season we always require mid to full throttle to start our 
3GM30F.  Starts much more quickly and with much less throttle in the heat of 
summer and when has been running within the past few hours.  I always advance 
the throttle when starting and then throttle back as all the cylinders start 
firing.  Injectors, hp pump and lift pump all replaced or refurbished within 
last two seasons

FWIW, on my Westerbeke, the owner's manual recommends starting with throttle 
wide open.  Don't know about Yanmar.  It helped a lot when I started doing 
that.  I guess it's good to read the manual sometimes.

Re: Stus-List Hard starting 3GM 30

2017-12-07 Thread Josh Muckley via CnC-List 
My 3HM35F starts with minimum throttle and in the dead of winter but I
still try to follow the manual.  Fred, you might try priming the engine by
pulling the decompression levers and turning over the starter for 10 to 20
seconds.  Immediately reset the levers and attempt to start.  You can even
reset while still rolling the engine.  If it changes the start symptoms
then I would lean towards a problem with the fuel lines draining down
during the idle times.  Could be sticking needle valves in the injectors or
sticking discharge check valves in the HP pump or weeping fuel line
connections.

I went through all of these 3GM30 engine issues for the last 3 years.
Finally came to my senses and in October I replaced the old tired 3GM30F
with a new 3YM30AGE. The difference is extraordinary & I only wish that I
had replaced the 3GM30 3 years ago.

Checking compression is a good idea.  White smoke usually means water in
the cylinder.  You might look for a leaking head gasket which a compression

What causes it to start poorly?  To start it we have to give it full throttle.  
One more clue is that when it first fires some white smoke comes out..

Somewhere out there is a wiring diagram for adding a second solenoid to a

straight away, don't have lots of time this AM but it IS out there.

This is a good thread for a possible fix:

One thing that strikes me is that you mentioned it's only one of batteries. 
This leads me to believe that one of your batteries is either weaker than the 
other or there is another issue that is only happening on one of your banks 
wiring.

Are your battery terminals clean and snug?

I have owned two sailboats and had to replace the battery selector switch on 
both.  I believe both were original and gave up the ghost around the quarter 
century mark.

The second one left me stranded and in need of a quick fix so I had to hire a 
mechanic.  My starter fried itself and the mechanic said it may have been 
partially due to the low voltage coming from the faulty selector switch.

Re: Stus-List Hard starting

2016-08-23 Thread Josh Muckley via CnC-List 
For years I had a problem where the starting circuit wouldn't always make
contact.  You could tell because the low oil pressure alarm wouldn't come
on.  I had thought I'd narrowed it down to the harness at the engine since
I could wiggle it to get the engine started.  It finally got bad enough
that I really had to figure it out.

I had made a plan to replace the multi-pin connector in the harness at the
engine.  I started poking around and found a fuse holder buried under
intake manifold in the valley between the starter and engine block.  It was
designed to be held together with zip-fies but evidently one of the POs
decided that electrical tape was sufficient.  I reassembled it properly and
have not had a problem since.  I've seen others on this list site this fuse
holder as the source of their starting problems as well.

How hard would it be to switch the batteries?
If the problem follows the battery then you know it's the battery
  itself
If the problem stays with the battery setting then it must be in
  the wiring

+1 on that. Once, I had a 6 V voltage drop on the battery terminal (corrosion 
and a wingnut). A little bit of cleaning, dielectric grease and proper 
tightening of the nut solved that problem.
Since you are saying that this happens on one battery and not the other (or 
more on one), investigate the cables on that battery and the connection to the 
A/B switch.

Stus-List Hard starting

2016-08-23 Thread Jean-Francois J Rivard via CnC-List 
Hi, I had a similar problem last year.  On mine I replaced the start 
button and that fixed the issue. 

Basically there are a few main areas to check: 

Connections on the batteries. They do get loose over time, obviously the 
easiest fix
Connection(s) at the control panel, I redid mine with crimp connectors as 
well
Connection on the starter


As mentioned it's a poor design to have all that current pass through the 
button on the control panel, I'm starting to consider adding a starter 
relay as well.  That's the proper way to wire a starter or any accessory 
that requires more than a few amps. 

Best of luck. 

Regards

I had a similar problem on Kaylarah.  I found the problem was undersized
wire in the harness causing a 7 volt drop in the power to the start
solenoid.  I solved the problem by installing a relay next to the starter.
Now the harness feeds the coil on the relay and the relay switches a #12
direct connection from the big lug on the starter.  The engine starts
instantly now, no matter the temperature.  Measure the voltage at the start
solenoid while someone else pushes the start button.  If you're not getting
at least 10 volts, you know what the problem is.

Good luck,

John,

 

Had the same issue a few years ago and eventually could not start the engine
at all.  After trying to find the issue with a multi-meter without success
I called in a mechanic.  He found the cause was poor / partially broken
connections in the wiring at the harness behind the Yanmar panel was letting
voltage show across but not sufficient amperage.  He cut out the old plastic
harness connection and directly wired things together with butt connectors.
Have not had that issue since.  

 

Good luck.
