OK Guys. I finally found enough time away from the campground business to check some things out on our 84 Eagle 10. I bought one of those IR Temp guns...very cool toy. I decided to crank up the 15KW Wrico Generator which is hooked into the engine radiator. I let it warm up...max temp reading at the water temp sending unit(strapped to the pipe crossing over the engine) was 157. I then went to the engine radiator which has an electric fan that comes on if you are stationary and started taking some readings across the radiator. Across the top was 157. Along the bottom of the radiator, it was 140 in the corners and 80 directly under the electric fan. And the temp guage at the dash for the generator read around the 157 temp(can't tell for sure because the guage jumps from 100 to 170). A couple of questions:
1) Does this seem normal?
2) As I had posted weeks ago when we brought the coach home, the engine temp gauge read 200 while the generator temp guage read 170. They are both plumbed together, so I'm assuming that my engine temp gauge on the dash is not correct, right?
I would have taken the bus out for a spin to do some more checks at full engine temp but my batteries were dead...another problem to chase down.

I had a similar setup in my 80 Eagle and everything sounds pretty normal as to what mine was.
I am assuming you were running the genset at no load and I suspect the ambient outside temperature was not very high. Under load, the genset outlet temperature should be around 180 degrees. If not you might need a new genset thermostat.
The auxiliary fan on the radiator really should have a thermostat that would turn the fan on if the inlet temperature reaches about 195-200 degrees. This would then help cooling for the main engine when you get to the mountain passes and the DD starts getting warm. It should be wired so that it can come on anytime the coolant temperature reaches this point, whether the genset is running or not.
Dick Wright at WRICO is a good person to talk to about this setup.

Thanks Richard for the info. I got the bus started this morning and I noticed that the electric fan was on, so I guess it is either not on a thermostat or is set wrong. |
