Yes. It is a dummy pulley, its only purpose is to keep the belt in place and tight.
Check alternator output with a voltmeter A fully charged battery should read approx. 12.8 volts without engine running Should read approx. 13.8-14.2 with engine running
A fully charged battery should read approx. 12.8 V without engine running With engine running should read Approx. 13.8-14.2 Volts
A fully charged battery should read approx. 12.8 volts without engine running With engine running should read approx. 13.8-14.2 volts
yes. it is a dummy pulley, its purpuse is to kep the belt in place and tight. ==answer no it should not turn at all if installed and belt is on it if belt is not in place, yes it will spin freely
The key has to be turned to the "Run" position, but the engine should not be running. The key has to be on to power up the ECU.
Bad alternator? A fully charged battery should read approx. 12.8 without engine running With engine running should read approx. 13.8-14.2 volts
Bad alternator- not charging battery enough to keep vehicle running check with a volt meter A fully charged battery should read approx. 12.8 volts without engine running With engine running should read approx. 13.8-14.2 volts
Check the voltage at the battery with engine running. It should read 13.5 to 15.5 volts. Any less and the alternator is suspect.
Perhaps the alternator is not charging the battery adequately check with a voltmeter A fully charged battery should read around 12.8 (without engine running) With engine running reading should be 13.8-14.2
Check to see if the alternator is working Connect a voltmeter to battery: Without engine running reading should be about 12.8 With engine running reading should be 13.8-14.2 If not bad alternator
Alternator not charging battery sufficiently? Check with a voltmeter: A fully charged battery should read approx. 12.8 volts without engine running. With engine running should read approx. 13.8-14.2 volts
Connect a voltmeter across the battery terminals without engine running reading should be around 12.8 With engine running reading should be 13.8-14.2 if you are getting these numbers alternator is charging battery
