Some have read my transmission problems and tach issues in my other post. After searching on here a solution could be a bad ignition switch. From what I have read you hook your meter to a ground and the trans fuse. I did this, When the keys are in the ON position but not started yet I get a reading of just under 5 (meter is set at 20V). When I START the burban it wonders a bit. Sometimes it drops to the 2.7 range. I was told this shouldnt drop under 9V. Am I testing it wrong???
