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. Mike |

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. |
