Genny cooling issues

[Dan]

Ralph, This is a little off the subject but do you still know where to buy the desicant cartridge 287313. I called o'reilly's auto parts but got zero.

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 Ralph - Thanks for the pointer. No such switch on my control box - there are three wiring harnesses (one on the back leading to the coach and two on the tront leading to the genny), one 10A bus fuse (which is still good) and the start/stop and preheat switches. That's all.

Thanks!

Hi Greg:

Open the gen set slide and on the left side of the control box see if there
is a switch. This is not the start stop or preheat switch. Some of the
Yammar sets have a switch that cuts the cooling fan off.
