    A customer has this controller and it shows "fuse" on the screen.... the fuse is good??? This system has been down roughly 6 years so I'm trying to get it back up and running.... it does have a rain sensor on it as well if that makes a difference.. thanks

    So did you check the fuse? You should stock a few extra 1 amp fuses (For standard controllers - some require 2amp and the odder ones are different too)

    To test a fuse you can typically just look at it to see if it's bad.. However with a multimeter you can check for continuity by touching each end.

    Be sure to ohm out your valves to make sure you don't have a short.. A short could pop your fuse again.

    Your question is actually pretty basic in the diagnostic world of irrigation. Maybe consider learning the trade a bit more before you start advertising with your lawn company that you are servicing irrigation. ?

    Yes my question is basic but the answer is not... if i felt i couldnt handle irrigation work, i would not advertise it, thats suicide to your own buisness.. I asked a basic question to get opinions to make sure I'm not overlooking anything before I go replacing a controller.... yes I've tested the fuse and yes its good.. my questions is... what could be telling my controller the fuse is bad when its not? Bad controller?

    I should have worded the original post better... I've checked fuses, tried resetting controller to clear fault, and unhooked ribbon cable to display..backup battery is good... yet still showing "fuse" in display..

    It could be anything, corrosion of the fuse holder? Replace the fuse for S&G, check the resistance between the prongs.

    May be the ribbon? replace it, they're cheap.

    Measure the resistance of the wire paths. Pay attention to low values.

    Facepack issues? maybe worth a R&R with another.

    Don't forget to measure the resistance of any interrupters

    Sorry I was thinking faster than I type apparently. I've never replaced just ribbon cables before...never had to. Can I get these from an electronics store or do they have to come from manufacturer?

    Im a bit of a pack rat (explains my profile pic), but i usually keep extra parts around that can't be easily obtained, especially with controllers, transformers, face plates ribbon cables. I try to upsell but sometimes the person is deadset on keeping the clock or the budget doesn't allow.
