So what is it that places a draw on the battery?
Wouldn't that draw be harming something when it is created.
I mean if something were at the ready so to speak, where is the current being dissipated if no work is being done?
Is something getting hot in waiting for some action and maybe shortening its life?
Is it a fused circuit?
What if the fuse blows and you don't know it? Will the 470 still tow properly?

Just wondering.
