q-tip Posted June 11, 2014 Report Share Posted June 11, 2014 I was just looking at Rock Auto and they have the 1990 D-21 alternator listed as having 70 Amp. Is there a specific year/model engine where they started using the 90 Amp. alternator? I think the reman ones from O'Reilly's are upgraded to 90 amp is where I got that from. Quote Link to comment

ggzilla Posted June 13, 2014 Report Share Posted June 13, 2014 1982 Subaru uses Hitachi 160LR, same as Datsun 210/510/720 a/c models Quote Link to comment
ggzilla Posted June 13, 2014 Report Share Posted June 13, 2014 They are 60 or 70 amp. If you go down to Oreilly maybe the parts guy can match up a 90 amp from a different Nissan that will fit the 1990 D21.

Parkinglotslider521 Posted June 14, 2014 Report Share Posted June 14, 2014 1998 Mitsubishi Eclipse GST alternator, 75 amps, had to figure out which two wires to use and swap the pully, then it worked perfect. although i do have to rev it above 2500rpm to get the alternator to kick on :confused: Makes the 521's headlights look like H.I.D.'s B) Quote Link to comment

q-tip Posted June 16, 2014 Report Share Posted June 16, 2014 will a bad alt.(iR) fry your starter solenoid ? Anything is possible really, put a volt meter on the battery with the car running, rev it up and if it goes over 15volts something is wrong. If it goes to like 25 volts something is still wrong.

Parkinglotslider521 Posted June 30, 2014 Report Share Posted June 30, 2014 So my eclipse alternator fried. Fitted a 90 amp alternator off of a 2000 saturn sl2. 1 wire, ignition switched to excite the field, 35.5 inch belt with a Lowe's turnbuckle and I got 1/2" of space from the steering idler arm. But it was a junkyard alternator so it fried. Now I have a squirrel on a pulley generating power. Little prick isn't running fast enough. Quote Link to comment
