TheDucks Posted December 4, 2020 Share Posted December 4, 2020 Make sure all Grounds (negative) are tied together (very critical that all nodes have the same ground. If you power inject from DIFFERENT supplies BREAK ONLY the 12V line where they meet. 2 supplies can fight You can safely set (well in the tolerance range)the voltage to 12.6 (5% high out of 10% limit) Link to comment Share on other sites More sharing options...
