What is wrong with my water softener Autotrol 740 Electrical problem?
I have a Autotrol 740 water softener that has an electrical problem. The transformer was blown, so I bought a new transformer and a new timer board. Installed them and the softener worked for 24hrs. After that, the transformer got blown again. I measured the outlet and it's ok. I am told that the timer motor on the softener could've gone bad....
Note; this all happened after a few lightning strikes close to where I live.

If there is a bridge rectifier or diodes directly down line of the transformer i would suspect it is bad.. put an inline fuse also on the primary side of the transformer and wouldn't hurt to put a fuse on the secondary also if the transformer only has two wires for the secondary..

Either it's getting old and you should start saving for a new one or you need to find a local water treatment dealer who is a Certified Water Specialist (find at WQA.org) to get yours rebuilt. If it's 10 years or older it will likely be cheaper in the long run to replace it. The softener with the fewest moving parts and the longest frequency to first repair also has the longest factory warranty on the electronics and valve: Autotrol. Built by Pentair Residential Filtration.
The fastest I ever saw a Kenmore softener thrown in the dump was seven weeks old. This was at the owner's insistence; just wouldn't remove iron. He bought an Autotrol with a turbulator from me. This was about 15 years ago and it still works just fine. He had his first service call 2 years ago. I've always thought that quality was more important than price, but if you wish to install yourself I can come so close to the "sale" price of a Kenmore.
There could be several reasons why your softener is not using salt. If it has a Demand Control the turbine that meters the water may be blocked and stuck so the softener doesn't realize that you are using any water, so it won't try to regenerate.
Your injector may be plugged, although this would cause the salt tank to become more full with each regeneration.
If you initiate a manual regeneration and regeneration does not happen you may need to replace the softener.
Knowing what make, model and age of your softener would help greatly in assessing. The best quality softeners last 15 to 18 years unless you have an Autotrol Turbulator in your softener, in which case add 25% more time; 19 to 23 years. There are a few brands that don't seem to last longer than 10 years...
Was the car primarily in a Southern state--no winters? If yes, it could be the wiring harness that leads to the rear wiper/stop light inside the rear tail gate. They usually break at the flex point, and short to the frame.
