thanks alot for the info dude

Well...I checked at an audio shop in town last weekend and the guy there referred Dominic Iraggi also. So I called him up and he said he will sell me a 180 amp alternator for $379. He said it is direct bolt on and I could have it in barely over a week I think is what he said. What do you guys think?

I'd find out if that 130a unit from an 01+ highlander will fit first.
You can get them off car-part.com for 75 and up.
A factory rated 130a will actually put out around the 180, they are very conservative on their ratings

Bud, your alternator is 14 years old.


Get a rebuilt one, unless youre running some serious SPL setup.


And yes, a spiral coil battery would help as well. Not only is the battery able to charge and discharge frequently, but it takes a FRACTION of the time to charge one than a standard battery.

If it charges in less time, you're less likely to kill it.

I have a drop replacement iraggi alt, works great, but I needed it to run my 2100 watt system.

well...what i think ive decided to do...partially by influence of money...is go to pepboys and get abt a 90a alt., optima yellowtop battery and also do the 'big 3' upgrade ppl have been talking about. if any more problems exist ill just get a capacitator....itll be cheaper than the HO alt and its gonna be awhile before i actually get to put my plans for my sound system into action so this will work for the time being....

A cap will will actually draw more current, once its used up the stored voltage, usually takes about 10 seconds to drain it.

I have a voltmeter on my battery and it sometimes reads 14.4v with my car started, does this mean i have a bad alt. Also how do you disconnect the positive wire on the battery where is it connected, i want to change it to 4 guage wire..thanks...

[eddiem67]

14.4 is perfect, check your voltage at your amp if it still reads 14.4 or even 13.8 dont change a thing.

[oibone781]

Ive been checking it all today, and it hasn't run a 14.4 again, i think the battery was cold or something. But anyway, i added a 150 anl fuse holder to the + on the alt to the +on the battery, and it still cuts off, next thing i will do is add a battery, i will maybe do this tommorow, if that doesn't work, i will change the ground wires, then if that doesn't work, i'll give up on my sound system, how do you disconnect the positive wire going to the battery...

oibone, are you having electrical issues? what is the problem, start a new thread and explain your situation.
