Figure 5 and 6: Positive side 12.3v. Ground side 0.30v: Normal reading. Electrically, this circuit is OK. Suspect a mechanical problem with the LOAD. Figure 7 and 8: : Positive side 12.6v. Ground side 12.60v. Figure 9 and 10: : Positive side 5.98v. Ground side 0.30v. But take the third measurement anyway. The reading close to, but not exactly, 0.00v indicates that the remaining voltage has " dropped " and there is current flow present, even if it is reduced. See Figures 9, 10. This is the combination that tends to throw most technicians off. The first reading is normal, showing that current is flowing. But that second one? One meter lead is on the battery ground post and the other is on the ground side of the load. With two ground points, how the heck are we reading voltage? Take a look at the next illustration to understand why. See Figures 11, 12. September 2022 3 MACS Service Reports Pete Meier Pete Meier Pete Meier
