SPRINKLER TALK FORUM - You Got Questions, We've Got Answers

We had an SRC Plus (9-station) Hunter system installed about 2 years ago. We live in Georgia and are prone to some pretty good electrical storms. According to the guy that installed our system, these storms keep blowing out our transformer. We had to replace it three times and currently can't find one so we're having to manually use our system. It's my understanding that this model has a built in primary power surge protection so why do we keep blowing out our transformers? The company that installed our system is now out of business so we're not sure where to turn for help. We have purchased a surge protector to see if that will help but we need to find another transformer to test in the next big storm. I think the controller is okay because it still comes on with a battery.

Any help/suggestions will be greatly appreciated!

We have 7 zones. Have no clue how to test the system wiring for bad solenoids. Can you help me out there? Good to know I can get an adapter anywhere. The guy that installed our system told us we could only use a "Hunter" transformer.

What am I looking for when taking resistance measurements? I guess my question really is, how will I know the difference between bad and good? What is normal?

Regarding the transformer, I'm not really understanding what you are saying. You said the Hunter transformer can't supply enough power to burn out the controller circuitry. If I find another that has twice the power but the same 24VAC output voltage, will I then be at risk of burning out the controller circuitry?

Thanks for all your help and yes I did try to use the Forum Search and didn't really find anything helpful. Maybe just not looking in the right place. Anyway, I think you've given us enough information that we'll be able to figure it out. Thanks again for your patience!
