GENERATOR OUTPUT LINE VOLTAGE DROP TEST

This test determines the condition of the wiring from the generator "B" terminal to the battery (+) terminal (including the fusible link). 1. Be sure to check the following before testing: a. Generator installation and wiring connections b. Generator drive belt tension c. Fusible link d. Abnormal noises from the generator while the engine is running. 2. Turn the ignition switch to the OFF position. 3. Disconnect the negative battery cable. 4. Disconnect the generator output wire from the generator "B" terminal. Connect a DC test ammeter with a range of 0-100A in series between the "B" terminal and the disconnected output wire. (Connect the (+) lead of the ammeter to the "B" terminal. Connect the (-) lead of the ammeter to the disconnected output wire.) An inductive-type ammeter which enables measurements to be taken without disconnecting the generator output wire is recommended. Using this equipment will lessen the possibility of a voltage drop caused by a loose "B" terminal connection. 5. Connect a digital-type voltmeter between the generator "B" terminal and the battery (+) terminal. (Connect the (+) lead of the voltmeter to the "B" terminal. Connect the (-) lead of the voltmeter to the battery (+) cable.) 6. Reconnect the negative battery cable. 7. Connect a tachometer or the scan tool. 8. Start the engine. 9. With the engine running at approx. 2500 rpm, turn the headlights and other lights on and off to adjust the generator load on the ammeter slightly above 30A. Limit: max. 0.3V When the generator output is high and the value displayed on the ammeter does not decrease to 30A, set the value to 40A. Read the value displayed on the voltmeter. In this case the limit becomes max. 0.4V. 10. If the value displayed on the voltmeter is still above the limit, a fault in the generator output wire may exist. Check the wiring between the generator "B" terminal and the battery (+) terminal (including fusible link). If a terminal is not sufficiently tight or if the harness has become discolored due to overheating, repair, then test again. 11. After the test, run the engine at idle. 12. Turn off all lights and turn the ignition switch to the OFF position. 13. Disconnect the tachometer or the scan tool. 14. Disconnect the negative battery cable. 15. Disconnect the ammeter and voltmeter. 16. Connect the generator output wire to the generator "B" terminal. 17. Connect the negative battery cable.

SOURCE: replacing rear wheel bearings on 1999 hyundai sonata

1. for drum brakes with sealed hub(all one piece) remove lug nuts and wheel.
2. spray penetrating oil around studs if there is a big phillips head screw visible remove it with impact driver/if not use big ballpeen hammer ,tap on flat of drum near studs(becareful not to hit them) until drum loosens(your creating a shockwave to loosen rust)
3. once drum is off there are 4-bolts coming in from behind backing plate, remove them then hub should be able to be removed w/a little persuation from hammer.

1. remove wheel
2. remove dust cap,cotterpin,star washer(if equipped) do not re use cotter pin
3. remove nut then washer, wiggle brake drum and front bearing will come out.
4. put nut on shaft tighten 2-3 turns grab drum by sides and pull towards you this should remove drum leaving inner bearing/seal on shaft
5. to replace reverse procedure making sure to pack new bearings w/grease(take drum and use long punch to remove bearing races, use race/seal installer to install new races

1. remove wheel
2. remove caliper/bracket
3. remove rotor
4. remove 4-bolts from behind,tap old hub out
5. reverse procedure

SOURCE: Major oil leak after oil change

Your filter was installed either without the rubber seal, or the seal wasn't lubed before installation and it slipped, causing an improper seal. You will have to drain the oil again, remove the filter, and make sure it is reinstalled with a proper seal.

dear friend-it appeares that you have no feul pressure,check pressure,feul filter,feul system,
