When I realized it was the bulbs (or wiring/resistors) my first thought was with the original papers and replacement list - think they were $48. Never even bothered to look on line. Yup, pricing is all over the scale.
I only have horses here during the summer now and it's the horse owner's responsibility to keep the fences intact. They have their own tester. They came one day to repair something and had forgotten theirs. I dug mine out and that's when we noticed.
As long as I get any reading at all, I'm good.
Thank you all for your responses!
I'll think of you all while I eat the cookies I've made for you in appreciation!
Meddle not in the affairs of dragons for you are crunchy and taste good with ketchup.
