I'm working through some battery drain issues with my FJ40: parasitic drain, bad alternator, and wiring.
Specific to wiring - is the white wire with the blue on it from the alternator sufficient? Should there be a heavier gauge wire? For example, should I get a dedicated heavier gauge wire from the alternator to the battery? What are the other critical connections from the alternator that require proper/heavier gauge wire?
