Hi Eric,

Hope that helps, go to the pic you want to post, click on "copy code to post this photo on a forum", choose the size, I chose 500, then right click and copy the code, then paste it on the page you are posting.

What engine is it by the way? 8v71?

Paul

You would think that as a mechanical engineer I would be able to do that!!! I use CAD in my business everyday to run my CNC machines, but I can't even re size a picture!! LOL I guess that is the difference between making cabinet doors and working on a bus!!! WE ALL NEED HELP ONE WAY OR ANOTHER!!! Thanks!!!

This is the 600 size. I wanted to include this for a better view of what you need.

I'm still learning myself, so don't feel bad, it all changes so fast I can't keep up!

What is your question exactly regarding the sensors?

You also might get some help on www.eaglesinternational.net. Come join in the fun!

On the curb side, the rearmost/largest unit is your alarmstat for high temp shutdown.  The front one is your engine temp sending unit. I can't see the driver's side unit clearly enough.  Can you post a close up?

Good luck!

also I just found what I was looking for! I have had trouble loading or resizing pictures here from day one! I recently found this thread and link very helpful! I down loaded it and now all I do is right click on the picture and click on re-size. Then when I get a choice I chose custom and put in 480 X 360 and it works like a charm!

If I can do it! You can too! FWIW Grin  BK  Grin

opps I forgot the link! LOL!

Thanks for the close up Eric!  That sure looks like another temp sending unit.  Double check for any numbers on  both units.  If they have numbers and are the same, sweet!

FWIW both heads should have a shut down stat in them and the right head (looking at it from the rear of the bus) should also have a temp sending too! (sometimes folks will put a temp sending unit in both heads with a temp gauge on both sides of the engine compartment for comparison purposes and not a bad idea either!)
If ya follow the wires or use an ohm meter you can tell which ones are hooked together which will be the shut downs.
Also if ya take a test lead and short them out to the block with the engine running it will either shut the engine off (if it has air and the system is working properly), or the temp gauge will peg full hot! One or the other it will not harm it to try this!  FWIW Grin  BK  Grin

Thanks guys for the help with the temp sensors!! I am down to the emergency. shutdown system to have everything done. My thinking is that there are only two reasons for this system to shut off 12v power to the fuel skinner valve. Low oil, and over temp. This means that both would need to be hooked in a series with the fuel shutoff which is controlled by the ign/ switch. I am assuming that the overtemp sensors (Left, and right bank) are normally closed. The low oil sensor is remote mounted. It has 3 wires which I have not put an ohm meter on yet. I assume it would be normally open. If I hook all in series the low oil will always want to shut down before the engine starts. Not a problem if the air system is down. However if it is up it will not work. I know there is a simple answer, just need the think tank to ponder it!!

Only problem with chasing wires is that I took em all off!!! Smart! probably not!! But I have been able to rewire the entire bus using the existing wire harness. The emer. system is the last part of the puzzle.

   I do not have my manual in the house with me (it lives in our bus), but I remember the my MC-8 schematic showed diodes to allow either low oil or hot engine to activate the appropriate warning device AND shut down the engine without activating the inappropriate warning device. The starter switch was also wired into this circuit to allow the starter switch to be used to override the auto shutdown, using a pressure switch on the secondary fuel filter to prevent the starter from energizing. (so you could at least pull off the road).  Jack

Eric they are normally open and whenthey get hot enough they close! Hence the simple test of the system is to ground them! FWIW Grin  BK  Grin
