High Output Alternator

Dariusz · 04-13-07, 10:32 AM

My Prado 3 door (Merú in my country) have a 70A alternator, and the output is 13.6V, is possible to modificate, change, etc. this to obtain 120A and 13.9V?

Thanks in advance

Nope, You will need to fit another alternator. Not sure if yours has a vacuum pump fitted but if it does you will need one that also has the vacuum unit on it. Mine doesn't have the vacuum unit, and I think it is a 90amp alternator. Depending on where you are you should be able to exchange your original for a high output one.

P.S. Why do you need the extra juice? Lights perhaps?

I find one in e-bay. It is a Tacoma T100 alternator (the same size and configuration as us) but with 130A.

I trie to install it the next week

You could change the stator from wye to delta configuration, and get an adjustable regulator to increase the voltage, but it won't hit 120a. More likely around 100a.
