The biggest problem I have seen is someone not familiar with electronics' is they find a board problem may see a burn's out part on the pc board electronics and right away try to buy a new board and install, Without finding out why the board burnt or smoked in the first place, hence guess what happens ? they burn the new board out and then come on the ogrforum and ask for help. biggest mistake you can ever make. there is always a reason when some part draws excessive current and the board burns' up again !
if your not sure what you doing it's best to ask someone the knows how to figure what the real problem is! did you see what happened to Alex M train he had to repair because damage due to person working on engine did not know what he was doing ! an ounce of prevention is worth a pound of cure!!!!!!!!!!!!!!!!!
