Can you add an Auxiliary Alternator to the iForce MAX Hybrid?

[vready]

The recent review of the 4Runner by Car Care Nut Mechanic mentioned that certain hybrid 4Runners (specifically, those with the pre-wired AUX port switches) include a traditional alternator that can serve as a backup in the event the hybrid motor can't charge the battery, and the vehicle essentially reverts to a non-hybrid.

If that's true, and the addition of an alternator provides increased redundancy/reliability, then it seems like a worthwhile upgrade to consider.

My questions are:

• Is the wiring for an alternator present on all 4Runners?
• Can you simply order and install an OEM alternator like this?
• Would the combined motor + alternator = higher amperage?
• Would an aftermarket high-output alternator be even better?

Interested to learn more about this...

I second that — I’d also really appreciate confirmation on which trims actually come equipped with the alternator. I'm still undecided on which trim to go with, or whether I should just opt for the LC250 instead. Also curious: does the LC250 come with an alternator?

My thought is that the wiring would probably not be there as Toyota would probably want to save money and only include it when necessary.

how on earth can we go about getting an answer to this question? Other forums i've been on have a master tech that will generally field these questions.....Bueller?

To the best of my knowledge only hybrid 4Runners equipped with the optional auxiliary switches (TRD Pro and Trailhunter) come with the alternator and its associated wiring. Non-hybrid models have a traditional alternator as standard, but most hybrid models without AUX switches rely solely on the hybrid system's DC-DC converter for 12V power.

The Land Cruiser doesn’t have an alternator.

Is that the same as the tacoma?

Yes, I believe that it is.
