This morning I gave the roid a 20 min low-watt warm up, then put the biggest load on it yet, 2700w, a room heater and an old toaster oven(man, I should have cooked something in it, I'm starved

)
These are temps after 45 minutes loaded to 2700 watts, ST5 in 120v mode, temps now stable. No smoke.
Room temp 32f - 0c, Radiator vertical size 34"h x 1.5"thick - 863mm x 38mm, 195f - 90c thermostat, 25% antifreeze, non pressurized, radiator core 75% covered on top both sides.
Fuel: about 15% WMO, ATF and diesel with a splash of Power Service.
F and C may differ a little because I have to change from one to the other and try to reshoot the same spot.

Engine outlet 219f - 108c
Top of cylinder head by injector 229f - 112c
Bottom of cylinder by inlet 167f - 75c
Inlet of radiator 200f - 95c
Outlet of radiator 170f - 78c
Exhaust before expansion tank 430f - 224c
Exhaust after expansion tank 295f - 147c (wow!, what a drop)
Oil filter 80f - 27c
Top of ST5 89f - 32c
Pulled radiator covers off at an hour and temps stayed stable for another 20 min(no fan) until engine just stopped all of a sudden.
Doh!! Out of fuel!!
Other observations:
Leaks fluids like an old Harley Davidson, O.K. maybe not that bad, just a couple of small leaks to fix.
ST volt gauge finally quit completely. At least I still have that little light

. Plan on removing box anyway.
Tried COV in and out, didn't notice change in sound or rpm. Left it screwed in.
Very little diesel knock once warmed up. Sounds great!

I'm happy so far. Now I need to get this thing hooked up to power the house before some big ice storm.
Think I'm going to pull the oil plug today and put in 20w non synthetic till its broke in a lot more. I now have a mix of 30w and 15w40, pretty thick cold.
