ON my '96 Ranger, 2.3 L 4-cyl manual, there was about a 5 A parasitic drain. I looked for frayed/bare wires, but because of my limited multimeter, could not narrow it down. Took it to a mechanic who said it was the GEM module and so I decided to order and install one myself. Upon further probing with a better multimeter, I narrowed down to main fuse Mini#6 (15A), which when pulled reduced the drain to only 0.3 A. This was for the alternator/voltage regulator. So I took the alternator to Autozone and it tested defective. After replacing it with a new alternator, the same issue remained. More specifically, when a wire that is white with a black stripe was removed from the hot bolt on the alternator (the one that the positive cable attaches to), the drain reduces to now 0.15 A. So I thought some Bozo had attached a grounding wire to the hot terminal. But when not attached at all or attached to the alternator chassis, the battery light came on. So I am thinking this is not a ground but the wire for the voltmeter (battery gauge). Is all of this because of the GEM module being defective? (other symptoms include: turn signal flasher was buzzing when turn signals were not being used, although now it was not happening, cabin dome lights not working) The pick-up was just purchased and obviously was not taken care of well, but I am trying to remedy that. Please help.
