Do you ground to the alternator ground post?
As long as you either ground to your alternators ground post or to the engine block itself then you will be all set.
What should the ground value be on an alternator?
To do this, take one of the probes and put it on the area where you are about to mount the ground on your engine and take the other probe and put it on the negative of your battery. It should read a value of 0 ohms to .1 ohms.
Is the engine grounded through the alternator or the Fender?
The engine is grounded through the alternator as it is and stock from the factory they have a dedicated ground to your frame/fender, and another ground dedicated to your starter motor. And in all honesty your engine is already grounded to the alternator since the bolts for your alternator go straight through the engine block.
How do you disconnect an alternator from an engine?
Begin by removing the dust boot from the main power terminal to expose the main power wire. If the wiring is difficult to access you will be able to disconnect it once the alternator is loose from the engine. All alternators are designed with a main power cable (large gauge) that is connected directly to the battery for main charging purposes.
What to do if your alternator has bad ground?
Place the red lead on the positive battery terminal (if possible dig it into the battery post, not the terminal). Place the black lead on the bad post of the alternator. Same thing as above, if the voltage is above 0.5v then examine the positive cabling for problems.
Where do you put the red lead on an alternator?
Place the red lead on the positive battery terminal (if possible dig it into the battery post, not the terminal). Place the black lead on the bad post of the alternator. Same thing as above, if the voltage is above 0.5v then examine the positive cabling for problems. Highly active question. Earn 10 reputation in order to answer this question.
Can a dead voltage regulator be replaced in an alternator?
At least a dead voltage regulator in the alternator. The voltage regulator can be easily replaced without removing the alternator most of the time, and usually is cheap so worth a try. Nevertheless, you should definitely clean those connectors and terminals every now and then. – galingong Feb 15 ’17 at 9:25
Can a bad ground wire cause a car battery to not charge?
The ground is a major part of the battery’s charging system, so assuming that you’re getting proper voltage output from the alternator wire, and the battery isn’t hashed, then you may be looking at a bad ground wire. If the ground wire is loose, then the alternator won’t deliver its full power to the battery, particularly at idle.
