Caution ... are you SURE you're hearing alternator noise and NOT the fule pump noise that Ford PU's are infamous for? I have one, BTW. If it's indeed alternator noise, take a look (Google) 'NEWMAR'. They have an extensive line of quality products. 73! Ken Kopp - K0PP [EMAIL PROTECTED] or [EMAIL PROTECTED] Hi Ken, Noise rises in frequency as I press on the gas pedal. I have also have read about the electric fuel pump noise but haven't detected it yet. Yes, I have seen the Newmar filters. They are very nice. I have seen one for at little as $125. http://www.tessco.com/products/displayProductInfo.do?sku=99967&eventPage=1 That's why I want to built one myself. If I can figure out what would be a good toroid core say in the T240 size, I think I can build one as nice for about $30. I might need to stack three, or put several wound toroids in series. That’s why I was looking for some advice since I am not good at picking out the correct toroid mix from the spec sheets. There are some toroids recommended by WA1MVX at http://www.sanantoniohams.org/Tips/whine.htm They are made by SIFERRIT and are ferrite, 64mm O.D., and type 87 material. http://www.surplusmaster.com/prods/comp/misc1.htm However, I don't know if a better material is available and I don’t know if I want to buy 20 of them.
