Chevy 1 wire alternator

[its-dat510]

Noob question just wondering what cars had the chevy 1 wire alternator im looking to put one in my 510 I went to a starter alternator place and the guy did not know what a one wire alternator was he asked what kind of car had it? I have done research but dont know what car has it or what car has it that will fit my 510 thanks

It will fit and work, the case is way different than the IR 280ZX one.  Custom bracket will be necessary.

what motor you have in tthis 510?

If L16 then the mount or holes will have to be enlarged. Not a drop in fit other wise get the stock alternator.(the GM alt)

If you have a L18/20 then get a 74/75 610/710 50amp as it has the bigger bolt holes.

 

 

If L16 Rockauto.com and parksgeek sells brand new Chinese stock type for like 65/70bucks.

 

 

If you want a 30min alt change get the alt for the exact year car. If its still a L16.

Im not a mind reader of your 510 maybe it has had 3 motor changes since new

Get a Nissan alternator, even one from a junkyard.  It will fit mechanically, and is probably more reliable than a rebuilt alternator from an auto parts store.   I have an alternator from a Nissan Pathfinder on a 1970 521.

Google search saturn alternator ratsun. The thread will come up. The saturn unit will put out more power than you could ever need.

New from Napa, NNE 1N4011ASW, 63 amp. Under $100.00. We use them on everything.

Are you sure they are new? REMAN is more likely.

One wire alts didnt come oem. Aftermarket or rebuild a standard gm one with a one wire conversion.

Another thread mentions marine grade hitachi which looks exact match but 70-80 amps. Saturn 90-95amp ones work but really should have larger pulley. Datsun high revs killed 2 in the 521

RockAuto/PartsGeek does list brand new ones but they made ein China. Power select brand.

 

Last 2 alt I got from  1 from Autozone and 1 from O Rileys are Chinese clones also but say rebuilt . They dont have the Hitachi or Mishibishi case marking on them.

I am assume the cores are even wearing out.

 

Iam running a O riley chese rebuid right now. Havent tried the NEW Chinese clone yet.

 

 

Nothing wrong with the GM units esp if brand new USA(those should last forever). Just they are not a drop in unit as most people think for the average Datsun kid(owner). Esp if a L16 in a 521(use the smaller bolts)

. a 510 has more room to work with and is EZer. as for that 80 amper as mention above this is a Chinese clone also (one I saw pictured)

A one wire alt is a flawed idea...

[banzai510(hainz)]

Yes the one wire is flawed and made for simple installations. The newer have sense circut 3 wire I believe

[G-Duax]

Been running a 1-wire PowerMaster for several years.

Only thing flawed about a 1-wire is if you buy a $100 (or less) chinky-chinese one.

[banzai510(hainz)]

Powermaster or Mean Green last forever  200-300$

Napa is new. NNE part number. Napa New Electrical.
