dickandlois Report post Posted October 3, 2016 There are a number of intermittent electrical problems that show up over time due to contamination. The top contender for signal issues are the older Bosch CAN bus, J1500 series circuits and the Newer J1900 series Data bus systems. Both are used so the Different Control modules used in the Injector pumps, ECM, TCM and other low level controls can talk to each other. Plus any 5 volt or 12 volt wiring exposed to harsh environmental conditions or where they are exposed to moisture or dissimilar material reaction. Thought I would post information on 2 products that do help reduce the problem. The first one is more forgiving Number 847- MG Chemicals Carbon Conductive Assembly Paste is an electrically conductive, non-bleeding grease for improving electrical connections between non-moving surfaces and parts. It was designed to work in the same manner as a heat sink grease, only electrically conductive. It is also good for globbing on bus-bars and other applications where a flowable grease is undesirable. It is non-bleeding and stays where you put it, so short circuits are less of a concern. As well, it inhibits corrosion, has a wide operating temperature range, a long service life, and does not contain silicone. Number 8463 - Silver Conductive Grease. This one is rather expensive and Because 8463 is designed to lubricate, it may migrate and cause shorts when used incorrectly. MG Chemicals Silver Conductive Grease is a higher end conductive silicone grease formulated for improving electrical connections between sliding surfaces and parts. It provides superior lubrication, inhibits corrosion, and repels humidity. It can also act as a gasket in EMI shielding applications.
