Ok, so I get it now, the old style solenoid, which I had one that last 10yrs/100,000 miles, and only went bad because of shoddy construction, in which the coil wire is just laying against the backing plate for contact, and the cheap gasket leaked, so it corroded and had no more conduction, that supposedly arced the contacts all the time, has to to be updated with the new $.30 diode solenoid for $10 retail cost....I love technology!
