Horton Fan

[Donald Spithaler]

Guys
I would like to know when my fan engages & disengages. Being a
pusher the fan is two far away. How would be a good way to wire it up.
I would like to have a light come on when it is engaged. Would the air
solenoid be a good place to tap into the wiring? I would like to know
at what temp it engages. I can tell it is working when I stop because
it will cycle on & off. How does everyone else know? I hope I am not
the only one that wanders that.

On my PT, is is fairly obvious, as the temp will fall when the fan
cycles on. It is not exact, but good enough for me.

Don I dont know about the fan on your bus but some air clutches are
engaged in the absence of air pressure. air is needed to turn the fan
on. that way the fan will be on at a failure of the air pressure system
(passive on). If you dis connect voltage or ground at the electric
over air switch the fan comes on.

Our 88FC fan is activated by an air electrical 12V solenoid.
An indicator light could be attached, but I think you would need
at least 70 feet of wire, and probably a relay for voltage.
I do not have this schematic, but possibly it could be attached to
the overide switch ??????
This is not impossible. And I think a good idea.

Greg -- Bill
When you put air to my fan it will lock the clutch. I just had it
off & rebuilt a couple of months ago. It was leaking air around the
hub. I haven't had time to check the solenoid to see which wire is the
12 volt. I want to know when the fan comes on. When it is cold my temp
stays at about 175 & when the outside temp goes up it runs around
190+or -. When it is warm out side & I stop for a break the fan is
running & then after a few minuets it cycles off then back on again. I
would just like to know if it does that when driving or if it stays
off longer. The fan would make a difference in you fuel consumption to
wouldn't it? When I turn my key off the solenod opens up & lets air to
the fan clutch & my fan will stay locked up till the air in the tanks
drain down. lf I turn the key back on the will release from the fan &
it will spin free. Bill if you figure out a good way to wire it let
me know.

Sounds like when 12 volts is complete at the 12v/pnumatic clutch
valve it stops air from being sent to the clutch and at the same
time allows the trapped air to exhaust.??? it might be that 12 volts
is always present at the pnumatic valve and the signal is sent via a
ground.

if you were to hook up a bosch relay to read the 12 volts input +
or - that turns the fan off and connect that acting signal to Bosch
terminal 85 you could mount a bulb on the dash and hook its + side
to Bosch 87a. Terminal 87 is not used. Terminal 30 is +12 volts
ignition power.Terminal 86 is powered depending on what signal trips
the pnumatic valve.

you may want to see if the fan override switch gets a signal
backwards when the fan comes on????? that may reduce the need for a
long wire between the dash and valve.

See link below and scrool to the bottom for using positive or
negitive input to power the relay

Greg
Thanks for the info on the way to wire it. I will check the over
ride switch before I pull a wire from the back. If I end up pulling
one I have a pull line I left in the wire chase from the last time I
pulled a wire so it won't be to hard to do.

Guys
I put a small light at the dash to let me know when my fan comes on.
I took it out on the road today to check it out. It was cold today & I
saw the fan coming on & off at about 170 degree. That seems to cold
for the fan to be coming on & off. What do you think? What is the
sender set at & does anybody know what degree it should come on at. I
always though the fan was running more that it should.
