SOURCE: 1983 GMC G2500 Alternator Belt Diagram

REMOVAL & INSTALLATION Fig. 1: A gauge is recommended, but you can check belt tension with thumb pressure 89771g18.gif
Fig. 2: Loosen the component's mounting and adjusting bolts slightly to remove or adjust the belt(s) 89771g19.gif
Fig. 3: Push the component toward the engine and slip off the belt 89771g21.gif
Fig. 4: Slip the new belt over the pulley 89771g22.gif
Fig. 5: Pull outward on the component and tighten the mounting bolts 89771g23.gif
Fig. 6: Accessory mountings found on 6.2L diesel engines 89771g24.gif

  1. Loosen the driven accessory's pivot and mounting bolts.
  2. Move the accessory toward or away from the engine until the tension is correct. You can use a wooden hammer handle, or broomstick, as a lever, but do not use anything metallic, such as a prybar.
  3. Tighten the bolts and recheck the tension. If new belts have been installed, run the engine for a few minutes, then recheck and readjust as necessary. It is better to have belts too loose than too tight, because overtight belts will lead to bearing failure, particularly in the water pump and alternator. However, loose belts place an extremely high impact load on the driven component due to the whipping action of the belt.

Have 2002 dodge dakota and brake lights don't work-have changed brake switch, checked bulbs, checked the 15 amp fuse and it's ok. what next?


Did you use a DVOM - digital volt ohm meter an test for B+ voltage to the brake light switch ? Who cares if the fuse looks good , if there is No battery + voltage on either side of the fuse it's not going to work . Looking at a wiring diagram to know which wires to check an using a volt meter to test is the proper way to diagnose .

How to test a blower motor resistor


Unplug the electrical connector to the resistor. There are 4 terminals on the resistor block. You test the resistor block using an electrical multi-meter, set to the Ohms scale. Using the meter's test leads, check the following:
Between terminals 2 & 3, you should have 2.3 ohms resistance.
Between terminals 3 &4 you should have 1.1 ohms resistance.
Between terminals 3 & 1 you should have 0.4 ohms resistance.
A bad resistor block will generally show infinite ohms on one or more of these tests. Look very carefully [magnifying glass] for the marks which identify the terminals on the block.

When i bolt the ground wire to engine behind alt, the ac compressor clutch locks on and stays on with key on or off. any suggestions???


The only thing it could be is the conrtol wire of the A/C compressor clutch relay is shorted to one of the wires grounding at the alternator . The PCM - engine computer controls the grounding for the A/C compressor clutch relay. Find the A/C compressor clutch relay in the under hood fuse box , pull the relay out of the fuse box an look on the bottom . You will see four sets of numbers . 30 & 87 plus 85 & 86 . Take an ohm meter an check pin 85 to ground with the ground wire's behide the alternator connected , you will have continuity . Disconnect the ground behind the alternator an you will probably have a open circuit . When the motor was changed wire's were pinched or something . Most likely . Here , check out the wiring diagram http://www.bbbind.com/free_tsb.html Enter vehicle info. year , make , model an engine size . Under system click on HVAC , then under subsystem click on HVAC controls . Click the search button ,then the blue link . Fourth diagram down is for the A/C compressor clutch relay circuit. Don't know if know how a computer controlled relay circuit work's . Looking at the diagram .The DB/OR - dark blue with orange trace wire would have to be shorted to one of those ground wire's for the compressor clutch to stay engaged .

Gauge showing low output alt only 1yr old wondering if it could be regulator or batt or wiring


if you have access to a digital multimeter, connect the meter (set to volts) across positive and neg. terminal of the battery, should read roughly 12.6 volts, close to 10 volts, battery may be going out, also test the alt output, disconnect neg term and place negative lead to battery neg post and positive lead to neg battery cable (make sure meter is set to amps) should read near the rating, if both those, then you'd want to do a resistance test, (set meter to Ohms) disconnect battery and connect meter neg to either pos cable terminal or where the pos cable connects to the alt and connect positive lead to opposite of neg, should read next to 0, the check resistance of the ground by connecting meter between batt neg cable and body of alt.
