so i took the alternator off. and took the back off and the diode bridge was melted. when i first got the van they told me the battery would not charge. changed the battery and everything worked fine for a while. now it won't charge again. it has the original alternator and 150,000 miles and the water pump is leaking a little around the seal and a few of the oil pan bolts were loose as well. typical high milage engine problems. so the only thing i can see that powers the alternator is fuse 3 and the auto shutdown relay that feeds the ecm by the battery that tells the alternator to turn off or on. is that correct or am i missing something? i was told there is a device that makes the regulator a part of the alternator instead of the ecm. are they any good?

 

well i fixed it for free. when i test i need to make sure the leads are plugged in all the way. now it charges at 13.75 volts i didn't have anything on but the radio and the engine. i still need an alternator but not right this second. this is not my daily driver. my water pump still drips out the weep hole and the tensioner still has a crack in it, but one at a time as i get money. tags first. if i don't renew the tags my apartment complex will tow it.

 

what other alternators will fit on this van? it has the 90? amp alternator would like to have the 120 amp alternator.

 

anybody out there?
