Generating trouble with Stray Current

This particular machine was on site for one year and 11 months as of February 2023 when these photos were taken.
The machine is a total loss, and the only thing that kept the entire enclosure in place during the storm was the fan shaft going through the intermediate bulkhead. Every piece of structure is rusted away.

This is all from the sulfur in the sprinkler water.

Aren't the enclosures at least water resistant?

They are resistant to falling water , but when you have a sprinkler spraying into the louvers they rust out quickly.

Man, that would suck.

They definitely weren’t happy. Kleetus the installer never mentioned anything to them about the sprinklers. He also didn’t mention anything about the developing damage when he came back a year later to do the first “service”

Damn! I've worked on fifty year old cars that didn't look near that bad. I think I'll stay in the mountain west...
 
Doing a start up on a nice little Kohler 38RCL this afternoon. The Kohler RCL series is by far one of my favorite small liquid cooled gaseous fuel generators. Brushless, quiet and fuel efficient. The 1800 RPM operating speed with a turbocharger is great for noise comfort while delivering excellent performance with surge loads. By far the tightest, voltage regulation and frequency governance in its class.

The aluminum powder coated enclosure and powder coated skid hold up exceptionally well to environmental corrosion factors.

I spy an electronic throttle body. Who makes that engine for Kohler?

Kohler builds the KG2204T in house for the 30 and 38 RCL. They used to KG2204 naturally aspirated version in the 24 RCL.

Impco technologies provides the ECM, demand regulator and megajector assembly

This engine block came out in 2016 or 17 as a replacement for the GM 3.0 and 4.3 packaged power products from power solutions international. Kohler parted ways with them as a packaged engine supplier.

The 305 and 350 from the 48 and 60 have been replaced with a Kohler KG6208, which, as I understand it is basically a 383 Vortec clone. That engine goes up to 150 kW. They turbocharge it at 80.
 
Some light service and maintenance on a 2003 Kohler 45RZG. Old school tech from the 80s

This is the avocado green refrigerator in your parents basement that will never die. The clock was replaced at 2700 and the new one is showing 611. This machine will still be sitting here hammering away at 1800 RPMs after the apocalypse.

Did a 60 point inspection on a machine we installed six months ago. It feels a little ridiculous trying to comply with some of the new flood regulations. Hey, I mean, the generator is fine regardless of the 3 feet of water in the house….

Start up and commissioning for a Cummins C60. We pulled a Generac 45 kW 3600 RPM screamer out after it drank 4 gallons of oil during a six day outage. You can’t turn a 2.4 Mitsubishi 3600 RPMs and expect it to last. Most of them rattle themselves apart.

The electrician who initially wired that 45 only picked up one 200 amp panel so we installed three new transfer switches to back the whole 600 amp service. There are 8 panels in the house but the 600 amp is seriously overkill for the load.

That 5.9 naturally aspirated 12 valve turning 1800 RPMs with a 5 gallon oil pan and 3200 gallons of propane on site should run for a good while. I’m pretty sure I heard the machine giggle when the switches transferred.

Why yes, those are spark plugs…

Um, spark plugs? Cummins? I didn't know Cummins made a spark ignition engine. I "assumed" they were all compression ignition. Learning all the time...

That is a 5.9 L Cummins block that is converted to operate on gaseous fuel.

The megajector, IEPR, and ECM are all one unit on top of the engine and manufactured by power solutions international. It drive six Borg Warner ignition coils that feed spark plugs where the injectors would usually go for a diesel. This particular unit is naturally aspirated, but the next size up has a turbocharger.

Is that O2 sensor bent or is that a optical illusion? If it is bent, the porcelain inside is probably cracked and it will fail soon.

I am not 100% sure why but they weld the bung to the pipe on an angle

Yea, I see the bung is welded on an angle but the sensor still looks bent to me. IDK

I’ll eyeball it when the customer returns and I go meet him for his monitoring app setup. I think it’s an optical illusion from the angle and .5 zoom though

Yep. If you look further up from the nut, the concentric rings on the body, and the cable exit grommet all have the same funky skew.
