Hi

I am curious as to the purpose of these two items:

thing 1 is mounted just above and left of radiator, in center grill section, its yellow button says 'push to reset'. TOP Pic

thing 2 is located behind driver side front access panel where the wiper motor is. BOTTOM 2 Pics

thanks for any ideas or even guesses!

#1 looks to be an air filter restriction indicator. If you look at it from the side, it should look something like this.



#2 Is an adjustable air pressure regulator. You'll typically find these on the stop sign arm or the air door arms. It's used to adjust the speed/force those air items operate at. Follow the hoses connected to it and see where they go.

thank-you, i was wondering where to control the door speed/pressure.

Follow the lines to be certain what it is used for. Typically the regulator for the air doors is above the door itself where the cylinders are. And usually the regulator for the stop sign is located in the compartment below the driver's side window. So being where this specific one is located, it could be for something else.

As for the filter minder, basically it keeps track of how much "vacuum" the intake system generates, when it reaches a certain threshold, the 'minder will "lock" to a yellow/red indication, at which point it's time for a new intake air filter. Reset this when the filter is changed. (Basically, it simply "locks" when a certain amount of "vacuum" is sensed, the yellow button releases it).

thanks guys for clearing this up!

thing 2 looks like the air valve for probably the stop sign or a pop out crossing arm if your bus has one..

Yeah it should be an air pressure regulator.

Look on your air filter. There should be one there to measure if your filter is restricted.
