Possible bad shut down device on Smith
by: Anonymous

Might have a bad shutdown device.

The bypass switch is used to get the unit running by taking some of these out of the loop during startup.

When you let the bypass switch go, they come back online, and if one of them is not satisfied that everything is ok, it will shut the unit down.

I`d suspect the low oil pressure shutdown first, but make sure you actually have the proper oil pressure before testing it! You can temporarily jumper the device with a wire to see which one may be acting up.

Does it try to rev up?

What's the pressure at?
