Genny cooling issues

[Wayne Kotila]

Hi Gregg:

I'm glad you got your generator fan working, You said you are running 190 deg. If you have a 190 thermostat on the gen. then maybe it's cooling fine and will still run around 190 when the ambient temp. goes up.

Good Luck andI hope you enjoy your trip!

Hi - Update on this project...

In our case the fan was wired into the breaker box on the side of the genny compartment. Someone (perhaps the shop that repaired the genny) had wired it into L1/L2, which since it's a 110V unit wasn't working. I switched the white lead to L0 and it's working fine now. There's a little more vibration than I'd like on the fan, so will be trying to adjust that. And as Wayne pointed out, one of the two blowers at the back top of the compartment was shot - the squirrel cage was shreded and detached from the motor. But the other's still working its little rodent heart out. I'll be replacing the dead one shortly. Ran the genny with all three cruise-Air units running (about 55A total load on both legs) and it peaked at a little over 190 degrees water temp after about an hour. This was with the
radiator shroud off and in the sunlight, but only 75 degree ambient temperature. We'll be in 110 degrees later this year and will need to make this work better. Hopefully the blower and the shroud replaced to improve airflow will give us the additional headroom we need. But always appreciate suggestions!

This is fun! I'm no gearhead - my college degree was in English & Philosophy. But I love learning new skills, and it is such a joy to have so much knowledge and willingness to share it available from you all!

We would make it to one of the BB rallys, but are a little afraid that we would be embarrassed by all of your beautiful rigs. We don't go for the classic polished look of a machine that just came off the showroom floor... But we are very concerned about keeping it running and functional. However, we are slowing decorating Bluefire in Burner style - adding animated elwire
on the outside and various fabrics inside, to go with the 15'x30' projection screen gear we carry on top along with our 16 foot tall Saguaro cactus.

With all this, we should be on the road east by Monday. First stop Phoenix and then on to Toast, an event on the AZ/NM border. Will post our story on our website (www.52weekburn. org) and will let you know when it's been update. It's empty right now.

Thanks again for all your help!

Ok:

The power to the fan motor come directly from L1/L2/LO. these points are located behind the vented plate on the back side of the Kohler gen housing and are on isolated studs. Were they wired back properly? The motor can be configured as 100VAC or 220 vac, double check the way the motor is wired then check the wiring from the motor to the isolated studs. You can see those connections in your gen set manual on the 2 line wire diagram.

Hey Fred!  Burners are people who go to Burning Man, an event unlike any other that takes place in the Black Rock Desert NE of Reno every year the week before Labor Day. Hard to explain, but it can have a really transformational effect on some people. To others, it's a party, or the biggest gathering of avant-garde artists in the world. To some, it's evidence of all that's right with society - to still others, it proves all that's wrong. http://www.burningman.com

Greg,

I'm coming into this thread late. But FYI I have the 12.5 Yanmar with the Kohler
also. My fan is mounted directly on top of my radiator (which is horizontally
mounted) and blows air from the fan through the radiator to the ground. Seems to
work well!

Ok:

The power to the fan motor come directly from L1/L2/LO. these points are located behind the vented plate on the back side of the Kohler gen housing and are on isolated studs. Were they wired back properly? The motor can be configured as 100VAC or 220 vac, double check the way the motor is wired then check the wiring from the motor to the isolated studs. You can see those connections in your gen set manual on the 2 line wire diagram.
