Now, I don't have the sealed beams installed, right now. But I turned the headlight switch on & the violet wire gets hot, BUT, there is no voltage there. And that is as far as I have gotten, so far. had to stop & work on getting a rental vehicle & a way to get there. Oops, forgot to include that with the new headlight switch, the high beams work with or without the engine running. Low beams, cause the amp meter to jump quickly, to the left (discharging, of course).
