Kohler 5ECD Generator

That's the way to say it!

Update: I replaced the injector today. I started it and it shut down two minutes later with an LOC (Loss of coolant) code. I forgot to replace it with the new one I ordered. I installed the raw water pressure sensor and it ran with no issues. I put all sorts of loads on it and it was rock solid. Hopefully it’s all good now. Before I pulled the old injector I tested the spray pattern and it was just pissing with no spray. If you get all types of codes, replace your injector before anything else!

Raw water pressure sensor.

I ended up not replacing the O2 sensor, I think the lack of a spray pattern was causing the EC69 code.

@aero3113 Aren't there 2 injectors?  How did you know to replace that one?

aero3113

@Spyderweb , it’s a two cylinder engine with only one injector.

Mind blown.

Mine too!

there is direct injection and multi port injection right? MPI....

Huh.  I always thought 2 cylinders, 2 spark plug, 2 injectors.  That looks pretty straight forward to change?

It's an mpi motor! Sounds like you have 1 injector than shoots fuel into the intake manifold...just like my 350 mpi boat motor...although I have not really looked to be honest. I tend not to look at stuff that ain't broke...got enough of the broke stuff to contend with...

Yes, very easy to change. The second time around to install the new injector took me less than 15 minutes.

Vvery interesting.   How much it's a new injector?

Black_Diamond

Basically throttle body injection.

Cost me $130.00

It was on auto. I wonder if maybe it needs to run for a certain amount of time before it shuts off. 

I again had a situation where I couldn’t turn off the genny from the panel.

When you guys run your generator, do you power the fridges with it or leave them on 12V and just run the charger?

Liberty44140

I power the fridge and ice maker with the ac switch with the generator, not the dc side. Spent all day Saturday on the hook with the genny on powering the ac, ice maker, fridge, charger, etc...

YYZRC

I use AC as well. 

Dream_Inn

When the genny is on, I power everything off of AC.  No reason not to & the load is good for the genny.

aero3113

Guess I was just being cautious, still nervous it will shut down on me again. I ran it yesterday for over 6 hours with the air conditioning on and charger, no issues.

@aero3113 when you run your genny you should put the highest load on it that you can. The bigger the load the better the genny likes it. When I run mine I put all A/C on. I even turn on my stove top. Genny does not like small loads..... Just say'n

Aqua_Aura

How does the top cover come off of the generator? I briefly looked at mine today as I want to change the spark plugs but getting to the back one on the 280 seems near impossible. 



@raybo3 I knew that fact but now after reading that comment it made me realize it's like revving an engine in neutral not having a load on the generator since the generator runs at its operating RPM somewhat regardless of load. 

YYZRC

I think on mine there were 2 long screws on the top at the back edge. 

LaRea

Look for smallish hex head screws ... 2-3 along each side, and two along the back top.  There are also pins that get inserted into holes, and its confusing until the first time you take it apart. 

The screws are steel, and likely corroded, so be careful.  I stripped one of mine, and had to drill it out.  

I replaced mine with stainless ... hope that won't cause a corrosion problem.  I have spares if you need 'em.  

Aqua_Aura

Ok I'll take a closer look next time I go down there. I checked the service manual and it says to clean and re gap at 100 and replace at 300. Generator has 190 on it so if it proves too difficult I guess I'll wait till  300. I don't have all the room in the engine room like you all. 

Liberty44140

My 5e had 4 hex screws on the top lid, one in each corner. Your newer fancy one may have less…

Black_Diamond

You need to be a bit Helen Keller on replacing the plug towards the hull. lol. Once the top is off or pushed back and the end panel removed, it’s not bad. Just did the plugs on my 5e on Sat. I replace every year and carry spares.  

Aqua_Aura

I'll dig in some more. I was worried I was gonna need a mirror and a third arm 🤣

Black_Diamond

Nah, won’t need a mirror. 👍🏻

There is a shortage on BPR4ES SPARK plugs, at least in my region yet BPR5ES is plentiful.  


Stock up on spares if you can find them!!!
