furrys/ss 0 #1 Posted June 2, 2013 Hello to all new to this forum working on a 1986 312-8 am I correct in assuming that the red power lead going to the test light board if disconnected will not affect the starting of this unit??? In other words the test light board does not have to be functioning to start the tractor? Tim Share this post Link to post Share on other sites
