Went out on an "irrigation box doesn't work" work order (jus luv 'dem edukated idgits) today and discovered that a slug had committed harikari on the circuit board. Board still seems to have power but there's no display. This is a new type Irritrol MC-E controller that was wrongly put in by a contractor several months ago. My understanding was that contractor was supposed to replace it (along with doing some other replacement work) with an MC-Plus-B controller as spec'ed out but it's never happened. I left it there and will let boss make the determination as to what he wants me to do.
