Ive got a weird charging problem, I thought was the alternator, but i took it to autozone- and it tested good. apparently I have a code for an open EGR, so they tried to sell me a new egr LMAO i dont think thats it) the battery checked out good too... So looking for some advice.
Started noticing the AC fan wasnt blowing as well and the engine was sluggish with gas, looked down and the [DC voltage] was only at about 12.3. Then it jumps to about 16 before going to 14.4 and holding for about 5 seconds, then back down to 12volts for a good while. It repeats this cycle regardless of what is plugged in.
Terminals are clean and tight, as are the engine grounds ... so im kinda stumped. seems to be a repetitive cycle regardless of what is turned on or off, and my mind is telling me its the alternator, so before I went to the effort of pulling I thought Id ask if anyone else might have experienced anything like this before?
FYI- im running the tundra 150A with photoman bracket ,alternator is 4 yrs old rebuilt OEM denso, prob 30K mi, and batttery is a 10 mo old duracel from sams club.
