You've most likely already have purchased the solenoid so this post is for informational purposes only.
Those solenoids are a high failure item that will most likely fail again. My recommendation is to bypass the solenoid permanently UNLESS you really do use that Battery Disconnect aka Salesman Switch. I would guess that most people do not including myself.
My solenoid has been bypassed for over 9 years now and I haven't missed it for one second.
BTW, they usually fail at the most inconvenient time which is the middle of the night and pouring rain outside.
