About Me

Based in South Dakota, I have performed stray voltage testing for over 30 years. Cases have involved dairy cattle, beef cattle, swine, sheep, goats, horses, and people. My goal is to provide relief to the animals, resulting in less stress, higher production, lower SCC, and better animal health.

If you’re looking for high quality and personal service, you’ve come to the right place.I’ll give you the attention and personal service you expect and deserve. I offer the best in investigation and analysis of your stray voltage situation.

Stray Voltage Problems

  • Poor production
  • Lapping water
  • High Somatic Cell Count
  • Nervous when milking
  • Not milking out completely

If you notice any of the above, stray voltage may be the problem!​


Stray voltage is the voltage difference between the electrical neutral/grounding system and earth. Some voltage will always exist and is normal for any electrical system. However, if the voltage is greater than 0.5-volts, problems will develop with livestock coming in contact with it. This voltage can be reduced to less than 0.5-volts.
