Hatless list member suggestion only: We have two essentially identical threads running on the same subject. Would people who reply to THIS thread please consider changing the subject line to Re: [EE] Using a p-channel power mosfet for supply polarity reversal protection ACTUALLY BETTER may be to copy the text from this thread and paste to an answer on the other thread. I suggest this because something strange MAY be happening. When I look at the subject lines in my browser, spaces are being missed out between some words, but not consistently. Also, it sounds like the subject changing that occurred initially may not have been person driven. If anyone knows what is happening here, do please tell.
