So right after we did rear rotors/pads (CLEARLY the cause of this problem), the voltage light started coming on randomly and the scangauge showed that my battery voltage was quite low, even at high idle. Then weird stuff started happening, for example: Scangauge wouldn't turn on, extremely high idle, hard brake pedal, etc. I've been taught that "weird" symptoms are classic cases of a failing 12v battery, so I have a new one arriving tomorrow and the old one on a charger. I figured if the alt was the culprit, oh well, I'd accidentally have two batteries for my dual battery system.
So my thoughts are this - I think I may have jumped the gun ordering a new battery, and that I may have a failing alt. That's terrible, except for the fact that I wanted to upgrade the alternator to the 150A. I've perused the thread thoroughly regarding this and I have a few questions -
1) How hard is it to replace the alt on a non-rusty truck with good tools? I don't mind removing the battery box or whatnot. Shame there's no video on it.
2) Do I need to upgrade anything besides the alt? For example, alt cables, etc?
3) Exactly what alt from the Tundra do I need?
4) What are the possible downsides to doing this?
What are your thoughts, mud? Thanks.
