Re: [Amel Yacht Owners] Generator failure (Field Breaker) won’t start

OK. I understand the model you have. I think it is better than mine because it is simpler.

Try this: Turn OFF the 30 Amp 230VAC breaker on the side. Try to start. Does it start and run OK? If it does, the short is external of the generator and your guess is as good as mine, but I would start with the shore power/generator solenoid box.

If you have the same results as before, the short is internal...if so, find an authorized Onan dealer/mechanic.

Good afternoon Bill,

Regarding the “Field Breaker” (check generator) I put a link to the pictures of my genset:
http://nikimat.com/onan_mdkal_b_specs_12_volt_kubota_d1105.html

For limited bandwidth, here is the pictures of my front panel
http://nikimat.com/onan_mdkal_b_specs_12_volt_kubota_d1105/onan_mdkal_b_specs_12_volt_kubota_d1105_1.jpg

I also have the DC Circuit Breakers on top of my Emergency Stop and the 30 Amp 230 VAC switch on the left side as well.

As of now, when I start the generator, the “Field Breaker” (check generator) will pop and shut down right away the genset.
I also suspect an electrical short somewhere… just not sure where to start…

Thanks in advance, sincerely, Alexandre

Alex,
I am not sure what you mean by "field
breaker." Could you explain that further. My Onan has
an Emergency Stop switch (breaker), a DC Breaker, and a
230VAC 30 Amp breaker. This 30 Amp breaker is on the left
side of the generator, the other two are on the main
generator control panel. Mine will not start with either the
Emergency or the DC set to OFF. It will start with those two
ON and the 30 Amp OFF.
Also, am I correct that you generator will
start and run, but shuts down when something...possibly what
you refer to as field breaker, is turned ON? That sounds to
me a an electrical short.
I know we have different models, but they
aren't that different.
Let me know.

Good afternoon,



The passage from Samana (Dominican Republic) to San Juan
(Puerto Rico) was rough (as the waive were in the nose, so
lots of pounding.



As usual I started the genset to recharge the batteries, 2
or 3 minutes later was a big waive/pounding and it stopped.


The “Field breaker” pop.



I switch off all the 220 volt device, press the “Field
breaker” back, started then shut down instantly, I tried
starting with the DC breaker off, etc. same it shuts down
instantly.

I don’t even know where to start to find the problem.



I own the ONAN MDKAL B Specs

http://nikimat.com/onan_mdkal_b_specs_12_volt_kubota_d1105.html

Unless I am mistaking there is no code to see (unlike the
more recent genset).



Prior that I only used the genset lasts week for 18 minutes
all was ok. Before that was a month before for 1.4 hour to
exercise all the systems and all was ok.



Thanks in advance for your help…



Sincerely, Alexandre
