What we don't know is whether or not it was a ground strike on the property. I remember one juicy little storm that zapped a few systems I service. Dead controller and shorted solenoids in one, and damaged above-ground PVC pipe in others.

Well, the simple answer is I got tunnel vision on the controller.
The old crime of deciding you know the answer before having all the facts. :S

why not start with a resistance test of all the zone wiring?

I'm sure there are quicker ways but brainstorming up here and assuming we don't have any replacement modules to use we ended up with this.
I'd love to hear a quicker method. Something like a hidden diagnostic button would be really good.

I don't know how many zones you have but with a good mulitmeter it wouldn't take as long as it sounds.
Still tedious though.

Previous advice

WOW! Sounds like a pain you know where!! I will have to wait until I have some help with that method--hopefully by this afternoon. Thanks for the advice.

I'm hoping some of the pros pop in with a shorter method.

All zones, manual start?
Tedious but...

Remove all modules but first.

Remove common wire and zone wires so you have an open common screw and open zone screws.

Turn on zone 1. If you get a fault message press the (-) button to clear.

Check voltage from common to zone one. Should have 24v+.

If the FAULT message would not clear then you have possible module problems.

If it did clear and you have 24volts then while zone 1 still on check rest of zones on module.

If they are getting power then bad module/controller.

If they are not, turn off zone one, hook common and zone 1 wire back up.

Turn on zone.

If FAULT appears problem probably in field wiring.

If FAULT doesn't appear hook wire to zone 2 and test.

If no FAULT, repeat basic process as you add each wire that is controlled by first module.
That goes ok, add second module, turn on first zone on module, etc.

Hunter I-Core modules

We had a lightning strike very closeby last week. Ever since, I keep getting error messages on the I-Core when it tries to open any of the valves to start watering. How do I check to see if the modules are bad? Any advice would be appreciated!
