Hello Mark! Thank you for choosing Kings Electric to meet your electrical needs. Today we troubleshooted your sprinkler pump and concluded that the wires had shorted due to corrosion eating up the protected enamel of the wire. We were able to resplice the connection while adding an extra layer of phase tape for added protection. We also added an anti corrosive to the electrical box to prevent further corrosion extending the life of the box. Thank you and we hope to help you again. Your service electrician Jeahn C Bermudez
