Hello Forums:
This vehicle would readily start some times and a jump was needed other times.
I disconnected the cables from the battery, the ground, and the generator
to clean the points of contact and to check the continuity of the cables.
A few minutes after I reconnected the 14ga brown wire to the side of the generator,
I noticed that the battery voltage was dropping like crazy. A coincidence? I pray that
the drop in voltage has nothing to do with connecting the 14ga brown wire.
A parasitic draw test shows that 60 ma of current are being drawn through
the 50A INT BAT fuse, located in the fuse box under the hood. Removing
the 50A fuse decreases the current to approximately 40 ma.
The schematic shows that the INT BAT fuse feeds five fuses located in the
fuse box on the driver's side of the dash. With the INT BAT fuse installed,
I removed each of these five fuses, which did not cause a drop in current.
I then pulled all the remaining fuses in the fuse box in the dash. Pulling neither
of these fuses caused a drop in the current.
Interestingly, pulling Fuse #4 caused the current to increase from 0.12A to 0.20A.
I guess that the current decreased from the 0.60A reading of the earlier draw test
due to the current drain.
I may be mistaken, but, I believe this current increase indicates an issue in the
circuit fed by Fuse #4. The schematic shows that Fuse #4 feeds the instrument
cluster and the TBCM.
The next step is to check the continuity of the wiring from Fuse #4 to these
two components.
Please offer any suggestions for troubleshooting or for things to check.
