Well here's a good one... Tons of rain here recently. Homeowner calls handyman for "lights out problem" Handyman goes to home and determines that because the VISTA MT-300 Xformer keeps popping it's circuit breaker, that the circuit breaker is at fault. Handyman removes on/off switch-circuit breaker from transformer. Skies clear. All good for 1 week. Big Rain again. Homeowner calls handyman, says "now my GFCI pops". Handyman says "Sir, you have a bad transformer" Homeowner is now pissed and is referred to us. Over the phone I say "sir, it's not your transformer, it's not your GFCI, There's a short in the field wiring." Homeowner says: how much you charge, I say "One million dollars to keep your home from burning down." LOL. Go out and ask the homeowner, Sir, by the way has anybody been diggin' in the yard recently? Homeowner says "as a matter of fact, my irrigation guy just replaced some leaky line. " Where would that be sir" "well right over here". Where is my shovel?. Two minutes later, what do I find, a severed wire along with burned wire nuts. "heres the problem sir, as I expected, Wasn't your transformer, wasn't your GFCI. Turns out you've got a voltage/shovel problem. Enter waterproof "Ace connector" to the rescue. Problem solved except one thing. Now I need a VISTA rep to help me fix the transformer. Need a circuit breaker/switch assembly. Any VISTA guys out there? What's you're tale?
