Ok one time 348 Alternator questions.....

Ok guys I need your help one more time. I have a 95' 348 with alternator issues. I researched all the treads and found the proper regulator and recitifers numbers to replace, well I think.

I know the Nipendenso factory Transpo recitifer IN 220 is crap. I upgraded to the Regitar brand recitifer and regulator and the the rectifier was a very tight fit when connecting the diodes leads, it fit but it was a tight fit.... I buttoned up the alternator with the new parts and connected the positive battery cable to the alternator, reconnected the battery cables and the cable started smoking.... Ok the cable must be grounding out I thought, so I traced the cable from the rear terminal block and it was not grounding. All other cables were just fine no grounding issue. So it is inside the alternator, but the cover is not touching anything.

Now the question do you think that the Regitar brand parts from the past posts were for an earlier model of the Nippo alternator? I used model numbers: regulator - #VRH2005-4A and rectifier - #RN-10 (The 8MM B+ connection version). If so could this cause the alternator to give the false signal of grounding out?

Does any one know the manf. number of the Nippendenso brand alternator used during the 95 year, so I can verify the parts with Regitar?

Also has anyone used this part? it is the OEM manf. but with improvements (??) I was told it was designed to replace the high fail Transpo part #IN220 and is a direct replacement. Here is the link: http://www.transpo.de/cgi-win/product.exe?INR734P.

INR734P REC ND replacing OE NIPPONDENSO

Diodes: 8-50 Amp Press Fit
Diameter OD: 113 mm
»» M6x25mm Battery Post (Note the smaller post of 6MM)
»» Welded Diode to Leadframe Connections
»» Like INR728 except with Ground Srew Hole


I have seached all the treads and I am questioning the part numbers only because no model years were listed.

I could have just a bad rectifier from Regitar but thought before I order another one I better check the part numbers in case I ordered the wrong parts and what the heck as long as I have the darn thing out I thought that I would replace everything the parts all in are only about $100.00 or so.

Any help would be great!

 

Thanks I did see that post. What is weird is that the rectifier didn't appear to ground out against the cover. I need to look again closer just to make sure. Its only the logical reason for what happened.

 

Thanks Ernie, it does appear that I need the 103MM rectifier. I also ordered a back up alternator from a 95 Acura Legend and plan on changing out the regulator on that Acura to a one that will work with our cars. That way I will have the factory one rebuilt and a cheap back-up so no down time if the factory unit drops out again. In Minnesota you only have a few days a year (it seems) to drive your car so down time while waiting for parts is not an option.

 

I wish I could find some numbers on the alternator, they appear to either have fallen off of been removed. I did notice the 113MM rectifier seemed to be in contact with the cover. I ordered the smaller 103MM just to see after all they are only $18 from Holcombe. I will let you know what I find out.

 

Well I have the smaller 103mm rectifier, The new parts came in and it fits like a glove. I wish I could find numbers on my alternator but now I know that the car is special in an alternator way....

 

Almost forgot the 103 MM rectifier part number is RN-04 from Regitar for 101211-5070 or 101211-5071. This part has the proper 8mm + post and is 103MM.

The regulator is the same for both the 113mm or 103mm rectifier alternator and is Regitar IN220.

 

Correction the proper part number for the regulator is VRH2005-4A from Regitar not the IN220 I listed above.... Everything else on the prior post is correct.
