Hey Guys, <<For a List of vendors who have supplied junk parts or didn't stand behind their products....see the bottom of the article.>> pepsi71ocean here. I decided to finally write this article up after another round of people with issues with reman companies. So a while ago back in 10/2015 I shorted out my PCM with a botched rebuild on my Alternator(I forgot to add a sealing washer!) As a result, after replacing the defective alternator I still had no charging on the

MAP (Manifold Atmosphere Pressure) Sensor The MAP sensor is installed into the rear of the intake manifold. The MAP sensor reacts to air pressure changes in the intake manifold. It provides an input voltage to the Engine Control Module (ECM). As pressure changes, MAP sensor voltage will change. The change in MAP sensor voltage results in a different input voltage to the ECM. The ECM uses this input, along with inputs from other sensors to provide fuel timing, fuel control and engine protect

My OEM alternator in my 2002 Cummins Auto was producing high AC voltage occasionally during very hot days and was causing my transmission to shift improperly (see Torque Converter Lock Unlock Issues). Many of us have had this problem and have tried many different remanufactured alternators to varying degrees of success. As noted in the torque converter article, AC noise is going to come from the diodes in the rectifier failing or failed solder joints in the alternator. Heat and load is

Starter Description The starter motors used for the 5.9L diesel engine and the 8.0L gasoline engine available in this model are not interchangeable with each other, or with the starter motors used for the other available engines. The starter motor for the 5.9L diesel engine is mounted with three screws to the flywheel housing on the left side of the engine. Each of these starter motors incorporates several of the same features to create a reliable, efficient, compact, lightweight and p

Stock APPS Sensor Voltage Adjustment I just had a wonderful phone conversation with Rburks this morning and his chasing his problems with his idle well he happens to mention the fact he did the APPS sensor voltage adjustment and I like "OMG not again!" There is an article on the Internet that is written up wrong and need to be corrected and/or stopped being used. To clear this up more... (The best I can) The fact is that the stock

Ok I know several members have done this mod and said it was easy. It sure is easy. It takes about 2 hours from start to finish to complete this project. You'll need the terminal lugs and the metric bolt that @W-T specifies in his article. First thing disconnect your batteries. I unhooked the two negative leads. You need to gain access to the loom going across the front of the engine. So you'll need to remove the upper alternator bracket and the the two loom holders on
