You are absolutely correct, the more voltage, the less current flow - to accomplish the same task. With a relay or solenoid, the issue is its specific ratings from the OEM company that made it. Many 6 volt solenoids - when you look at the small print of specs. - are designed to work with a minimum of 6 volts (or lower) and are often rated as high as 18 VDC. It is unlikely you're gonna' find any specs. for a used solenoid - but it's a $7 item - who cares? In my own experience, I've never seen one burn out or suffer from high voltage. I have seen many get destroyed from low-voltage. I recently made a stupid mistake and a brand new starter went up in smoke. I installed a new-old-stock diesel engine into my Case 580CK backhoe. As I said - new including all electric components. It came from a US military base. Well, it cranked slow which p*ssed me off. I had new batteries, good large cables, etc. I was in a hurry and wanted to hear the new engine run. So, I figured there was a bad connection somewhere - and I ran an array of jumper cables and more batteries. The starter just spun slow and grunted, the solenoid closed slow, etc. Finally, smoke poured out of the starter. So, I finally put my glasses on, looked close at the starter and solenoid - and it was all marked 24V. Duhh . . . ! Boy, did I feel like an *sshole. Then it dawned on me - most military stuff uses 24 volts, even their SUVs and pickup trucks. Seems their Case equipment is also 24 volt. So, I had to get an old 12 volt starter, and also find a 12 volt solenoid for the fuel-injection pump. I still feel like an idiot.
