Intermittent Electrical Problems
Wrong gear starts, no upshift, no downshift, falling out of 4th gear, etc may be caused by poor grounds. This applies to any electronically shifted unit,
import or domestic.
To test for a poor ground, connect the black lead of your digital voltmeter directly to the negative battery post and probe the suspect ground wire with the
positive lead. A good ground will read 0.1 volts or less. More than 0.1 volts is a poor ground. Keep in mind the circuit must be operating to accurately
check the ground.
