Now, that makes sense! Even a 30 amp load at 14V is 420W, more than half a
horsepower. Factor in the losses and the small reasons not to, and it is a
reasonable thing to do for a race. Of course, a 140 ma load from the window
relay is right at 2W, or about 1/370 of a horsepower.

Google Cheah pet's previous posts in this group. He has stated that
Hondas are defective because they have electric clocks which draw
current. A real looney.

I remember that thread. I believe one of the claims that time was that
because of that "defect" a Honda could not possibly cruise down the
highway at 60 mph. I say TE Cheah is a troll.
