Just a little bit of info. I have an Iraqi alt in my 1991 Corrado, I believe the 220A IIRC. It has helpedge not chew throw a main battery as quickly. Ate a megatron in 3 years and a red top in 5 years with the stock bosch 90a.
Threw in a yellow top, till the bosch 90a spun the pully. 2 years later. Same cost for the 220A as a oem bosch 90a. No brained their. Ran the Iraggi alt for 5 more years, tull car went down into project status.
The only issue is I have auto start in the car and with the Iraggi alt. there seems to not be enough excite current goING to the field to kick on the alt. I have to bump idle revs to about 1000 to 1200 rpm to get the alt to output current.
I.E. Idie current is low.
