I want to put a second alternator where my power steering pump is on my 7afe.. haven't had power steering since November because when I swapped my engine one of the lines got busted and I'm not too concerned with having it. Just wondering how you guys would go about doing this. I have a battery isolator. Red top optima under the hood. Yellow top in the back for my mini fridge (don't ask) on a 1000 watt pure sine inverter. And also for my 4 12s in the hatch. So obviously the second alternator will be for the yellowtop. That way I can get rid of the isolator and have a second charging system for all my addons. I know it can be done. How would you guys mount the alt?

Look into the MR2's. They mount the alt where the PS pump is in our cars. You may be able to use the mounting brackets from an MR2 but I don't know if they'd fit a 7A.

A charging system only for my fridge.. ya know.. only for the inverter and the subs. And the stock alt does its normal job powering the red top under the hood. So when I get in this car after work at 2 am I can run my lights and have my yellowtop be charged back up after running a fridge for 10 hours and not worry about my alternator being overloaded because I know it is. So if the alt that charges the yellowtop everyday goes out I won't be stuck on the side of the road
Yes I have a fridge in my car because people at my work steal food.. it's isolated from my starting battery so it doesn't kill it leaving it on. And I have a 92 mr2 so I'll look into that. They have 2 places to mount an alt on that 5sfe. Maybe I'll get lucky. I'll let you all know how it goes. |

They are very similar as far as I know and that thing looks like the mount holes are just like my power steering bracket. That might just be what I need right there. I can handle the wiring.

There are videos on YouTube of people retrofiting camry, highlander and beams alternators into hybrid 5sfe alternators. Upping the output.
