why if there is no power to the electrical system after the battery is switched off and you go home for the night, why the solenoids are still "alive" and therefore apparently wearing out?
Hudson, imagine switching ALL 4 pumps off in the Shutdown cklist: by doing so, you would
energize the solenoids, only to
de-energize them after a few minutes by switching the battery off.
The opposite would happen the next morning.
Now you can imagine all these useless solenoid cycles...
