Any one have any ideas for adding an alternator on a 1998 ford ranger with the 4.0 in it.

 

Adding a 2nd alternator or replacing the one already there ?

 

yeah I would like to eventually add a second alternator.

 

Welcome to the forum

Why?

You can buy a 200amp alternator to replace stock alternator

If you don't have/need AC you could build a bracket at that location and use the 4.0l AC fan belt

For most extra power requirements a second battery is the better option, since alternators can only produce 50% of power rating at engine idle RPMs

If you need the extra power while driving then pulley can be installed on drive shaft, at transmission end, and it can be used to spin 2nd alternator

 

Ok thanks. That helps me alot. I'll try the bigger alternator first thanks again.
