Poor grounds are a common source of all types of codes and driveability issues, as is low system voltage actually reaching the component due to poor connections or wiring damage. The best way to test for this is by "voltage drop" testing. The technique is described in detail in my book Automotive Driveability: A Guide to Engine Performance Diagnostics. You can get more info at my home site at www.autoservicetech.com or visit my bio page.
Hope this helps!

Why is the voltage regulator overcharging the battery in a 1990 Ford econoline?
A bad voltage regulator can cause an overcharging condition. Check the wires going to the regulator for corrosion and make sure the regulator has a good ground.
How single point grounding reduces ground loop?
A voltage can be induced on a ground wire by other wires nearby. If you have more than one ground wire, The induced voltage will cause a current flow up one, and down through the other. By removing one of the two, you interrupt the loop.
How you know if the wires black and white are mixed?
You use a known ground and check them for voltage. You can use an extension cord to reach from a ground to the wires you are testing. You are not putting it in an outlet, just to connect you to a ground.
What are the 3 wires on a map sensor for a 5.7 hemi?
5 volt supply, sensor ground and signal voltage.5 volt supply, sensor ground and signal voltage.
Will a voltage regulator just go out?
Yes, if you have a poor regulator ground connection, shorted wires etc. What is the application?
Why would your distributer cap cause a you to be shocked when you touch it?
AnswerBecause there is high voltage present and as the cap and wires get older a certain amount of current will pass on the outside of the cap.( May be an indication of a need for wires and cap, rotor) So when your body provides a better ground, the voltage will jump thru you instead of the spark plug wires. Wakes you up quick right? MarkUsually because there is a crack in it. It should be replaced.
What wires in a 2003 crown Victoria will cause it to not start?
What makes you so sure it's wires? Any loose ground related to the cranking system can cause it, faulty spark plug wires will also do it.
Can you put low voltage sound wires and low voltage light wires in the same conduit?
noyou can not
What colour wires are live and ground in 96 mondeo?
Normally Red, Black, or Orange are hot and Green, or Possibly Brown are ground. To be sure, use a voltmeter, set for 12 volts D.C. and check each wire for current. Once you have isolated the wires carrying voltage. then switch to OHMS and check the other wires. Wires that are grounded will show a reading in OHMS.
How do you identify the hot wires if they are not white or black?
You can use either a volt meter and go from the line in question to ground and see if you have voltage. You can also get a non contact voltage tester which is what I would use and place it on the wire in question and it will beep if voltage is present.
