On a 3rd gen Tacoma, it can only be done with a tune adjustment to electronically tell the alternator to raise the output voltage to 14.6vdc. There is no other way to do it, no addon device that I know of to raise it from 13.8 to 14.6. Even with an aftermarket high output alternator, the computer will tell it to output 13.8vdc. The problem is that every time I talk to a "Tuner" to see if it can be done, they want to sell me a complete tune package that alters everything from throttle response to shift points. I don't want all that. I simply want to raise the output voltage; I'm happy with everything else about my taco. These Tuner guys are like high pressure salesmen.
@@swade417 Yeah that’s what I’ve been looking into. I think if R4T is pushing using these G31 batteries or any AGM they should at least let folks know of the issues involved with going AGM. My $0.02
@@ryanskeeteas an electrical engineer understand higher voltage means more stress and a guaranteed shorter lifespan on every component exposed to the higher voltage. I personally wouldn’t touch it unless it was creating huge issues where my truck wouldn’t start
@@Runnin4Tacos Just an update for anyone wanting to know if it works for 100 series. The negative terminal cover sits too high and can’t close the hood. Right now I have just the positive terminal cover, i shaved the spacers about 1/8”. Although, in theory you should be fine with the negative terminals exposed I made a cover for the negative terminals out of a thin sheet of rubber i found just for peace of mind.
