Hunter Pro-C causing power surge

I have a Hunter Pro-C that is causing a power surge. Here's what I figured out so far:
Ran system from the garage (GFCI) power went off to this circuit when it reached station 3 (ran for 25 minutes).
Ran system via extension cable from the house power surged when it got to station three, but the system kept running.
Ran system starting at station 4, when it got to station 7, it ran for a couple of minutes then the GFCI blew (ran about 35 minutes)
I would really appreciate any help. Thanks!

You might be getting nuisance tripping. In general, the supply transformers of these controllers can be trusted to not have any shorts to ground, which is what is supposed to trip a GFCI.

Are any of the zones giving you error messages on the controller display?

Check to make sure that your zone 3 is not getting water in to an electrical outlet outside. It may be an unprotected and exposed electrical outlet.

Good Luck :thumbsup:
