How come you dont just use an higher amp Leece Neville?
most are 2 wire hook ups, but if you have a three wire hook up dont use the indicator wire, there is all types of higher amp alternators from Leece Neville: http://www.prestolite.com/pgs_products/products_0.php
If need to just give us a call m - f 8:30 to 5: pst
800-289-2737 and see what we can hook up for you.
Try to get the unit number off your alternator....
