I recently replaced the solenoid on my White LT1650. I have it running now but as I was troubling shooting the repair I realized that I was getting a voltage reading across the solenoid. As I understand it there should be no charge across the solenoid until I turn the mower on. With the key in the off position I show a full 12 volts across both nodes. Is this correct or do I have some sort of wiring problem somewhere? Thanks.
