Bought the reducer diod sold by Wrongway. $8 or $12 with shipping. Will that servie a smilar function to an "opto isolator" ? As I undestand, it should insure a steady voltage from my 3,200mAh Li-fe battery to my ignition on one lead while the rx is power by another lead. Or do I have something mixed up here? How do I acturally wire up the rx and ingition off one battery with the reducer diod in line?
Thanks for you help.
