i have tried 2 remanufactured alternators & there not charging what would cause them to not charge ?

make sure the heavy red wire is 12 volts.

the other connector will have a hot wire, key on. does the light work on the dash??

thanks for the reply asemaster 6371 ! there's only a gauge no light. i tested the heavy red wire with a test light & there's power, i tested the connector wire and it has power with the key on. tested the battery with dvom & it reads 12.58 with the van off & it read 13.89 w/van running. sometime when i turn the van off & restart the charging voltage will read 13.01 & start dropping down into low 12's

ok, then it leaves the alternator itself. what kind are you using??

if im not mistaking its a delco reman. im not absolutely sure, i purchased it from a local parts house. i dont know if they do in house rebuilding but it has a warranty. i really would like to try another rebuilder,this is the second alt. from these guys, ill replace it today & see if the problem go away! thanks again asemaster6371 ill let u know the outcome !!!!

good luck
