Whats the difference behind a 24v 5 wire External mounted Voltage Regulator and 6 Wire External Mounted Voltage Regulator ?


hi i have a few NipponDenso 5 wire NOS voltage regulators

i also have 2 different 6 wire ones

ALL 24v........fyi


however i was asked for a 6 wire for a HJ61 and i can't find ANY info anywhere online except 2 different 6 wire part numbers OEM that claim to NOT interchange ?

27700-57080

27700-57090

this is very odd to have such a vacuum of no TECH after digging here on MUD in advance search too

thanks for any and all input ...........

This is my 5 wire I have going on

It should cover a Bj40 , 41 , 43 , 46

But NoT a 42 ?


Maybe I’m wrong too ?

 

[DEADSALT]

what’s the sixth prong for the 42 for....?

 

[DEADSALT]

both 24v

 

[ToyotaMatt]

both 24v

i cannot find out this is why i posted the TECH thread ?

anyone ?

 

[DEADSALT]

gotta be a difference between B and H series

what colour is the extra wire
and are the other five the same between the 5 and the 6 prong

 

[DEADSALT]

just checked - 1980 Canadian bj40 24v - six wires/green connector

not a B to H change.

5 pin were maybe pre 74 or odd market/no heater

a ROUND type green connector 6pin correct ?


like this ?

NOTE: this is a sample connector ONLY photo and NOT from a related TECH> regulator topic , as it only has 5 pins too ....

Matt,

My 03/81 General Market (S. Amer) BJ40 - B engine (but, with many 3B attributes... oil cooler, late water pump, etc.) - shows a six pin regulator.

P/N: 27700-15011 is stock according to toyodiy.

Also, this is a snip from the wiring diagram that I used to rebuild the wiring harness; shows six wires to/from V/R:

I can't tell from the pictures that you posted if your 5-wire has a Yellow wire. But by the wiring diagram the Yellow wire on the six-pin V/R is optional. FWIW, that yellow wire comes FROM the (+) side of the Sedimenter warning light (before the float/switch in the sedimenter that would trigger the warning light), through a diode and into the V/R. I'll stop short of speculating on what that yellow wire DOES within the V/R 'cause I don't completely understand the relays/switches inside there...

I'm not sure this answers your original question (which, I think, was 'what do these 5-wire regulators go to.?') but I hope to help,
Trav.-

I suspect the B (battery) connection is missing on the 5 pin. You could technically use the IG (ignition) pin as a substitute.

 

[hj 60]

I have the 6 wire, at least count six wires, it is explained somewhere, ignition or battery: no need to try to charge if engine is off.

From here, where mine tried to fry itself, picture to large to attach so a link

hj60-24V glow,alternator,dome,buzzer,battery, electrics

The charging is 14.4 but the Amps are not fine and there is a powerdrain. The batteries can handle 17 more amps when charged with a good charger. wiri

a 27700-15011 is a 12v regulator correct ?

i have new part # 27700-15040 , it supersedes back wards and side ways a bit before i nailed this one down !

THANKS for the tech !

i only pulled the case lot trigger today on 6 wire 24v made in japan regulators, because of your post , i think these are gonna help alot of folks out ,

we will see

time will tell

NOTE:

i ONLY will post Confirmed part# interchanges i confirm WITH DENSO / NipponDenso Headquarters japan ............fyi

Yeah, 12V. (again, sorry if I clogged up the thread with my non-answers.... haha)

You have a LOT of stuff I need (V/R is just one of them); I'll give ya' a call in two weeks - got some travel that I need to complete before the next parts order - but certainly I am at the point to need a bunch of vintage, quality, TEQ, correct stuff!!

Your Input Master Chief IS ALWAYS welcome and VALUED in my threads ............

 

[ToyotaMatt]

I think maybe it's time to call in MY personal Expert on regulators ........

@bj40green Rudy wrote a College professor LEVEL Thesis on regulators , just not sure how much was 24v related ?

time refresh Mr. Rudy's passionate thread of a helpful nature ..

I will post the link once i find it again ...HERE

The voltage regulator of my 24v HJ61 just died.
I am searching for a replacement. Part reference 27700-57090 (what I had) isn't produced anymore but I can still source 27700-57080. From what I understand 27700-57090 is 24v 30A, and 27700-57080 is 24v 25A.
Can anyone confirm, and most importantly are these parts interchangeable?
Cheers

Thank you. What is the amperage of your regulators?
