Your last generator Maintenance Run

[3930dave]

You don't have a probe that can connect to 240V?

Possibly common in the Utility or Power world..... somewhat less common on the Electronics side.

I wanted to highlight Nick's use of a transformer, to hopefully lessen the likelihood of somebody grabbing a borrowed scope to play with, and blowing a regular probe's ground clip into next week. I've "heard of a guy" doing that .

I think it went, Wisconsin, then Wisconsin- Robin, then Robin-Subaru and now I see them just called Subaru's...

DM

I was thinking it was something along those lines...... last I looked (2-3 years ago) Wisconsin still had a line of pretty serious (meaning non-consumer level) industrial small engines.

Howdy,
It's that mid-point time of year. Time for major re-fueling

Date: July 17, 2015

Generators: Coleman PowerPulse 1750, Honda ex4500, ETQ TG72K12, Generac 6500EXL, MEP-802A 5kw, MEP-803A 10kw

Activity: Gas units simple load of 2 1500w oil filled heaters,(1 unit on small coleman) voltage and Hz monitored, each loaded for at least 1 hour with fresh fuel. Diesel units were loaded with load bank for 100% load respectfully for 1 hour. All fuel topped off after workout.

Final Fueling notes: Siphoned all gas out of units, placed in truck, re-filled with fresh 100% gasoline and red stabil. Diesel units topped off.

Maintenance notes (Done, or Required): Oil changed in all gasoline units. 5w-30 synthetic. Diesel units oil level good.

All batteries placed on smart trickle changers for at least 3 days.

Conditions: Bright and sunny, 83 F deg.

On the farm, up early, getting lots of work done - I like your style Mike !

I'm curious, what are you using for a load-bank on those diesels ?

Howdy,
A surplus military load bank (Essex Electro Engineers A427 0-33kw) single phase and 3 phase

Now, that's a load bank !

One downside to hanging on TBN is that I keep finding New Toys I Want :shocked:

aka..... Critical Maintenance Tools.... depending on who is listening

All drooling aside.... it is fun to see what you get to play with when budgets are virtually irrelevant. In past for-hire work, I've made do with everything from dead batteries, light bulb arrays, and even a carbon pile..... watts is watts, but pushbutton at that power level would be fun.

Thanks for the equipment details and pics Mike !

When we got our place in NH, we were advised that the area lost power "all the time." So we purchased and had installed a 14KW Kohler running off two 100 gal propane tanks and an automatic switch. So, of course, we didn't skip a beat through 10' of snow.

Last night one **** of a line of thunderstorms came through: if you want to see what it was like, fast forward to 15 seconds.

The lights flickered and went off at 7:12 and came back on a few seconds later with the genset. It was still running when I left at 10am, though power has now been restored. Wish I'd checked the fuel level at start to get some idea of consumption.

Engine is a 725cc air-cooled Kohler V-twin using 45-80 cfh (1.2 to 2.2 gph).

Storing power (batteries driving inverters) seems to get more attractive to me as time goes on..... on that Kohler, going from 25% load to 100% load only doubles the propane consumption.

One thing I like about propane or natgas is how clean the engines run...... enough so that you can't go by "Change the Oil When it Gets Dark".....

Even at 100% output, you'd only have used about 35 gal in a 15 hour run.... nice setup :thumbsup: .

How quiet do you find that Kohler GM ? I haven't seen one of those yet.

The specs are 63-67 dBA. The Kohler spec says the quietest competing systems are 58-63.

We mounted ours on the far side of the garage (that's where the fuel was) and with the windows closed on that side of the house you don't really hear it at all. If I had to do it over I wouldn't change a thing.
