can a auxiliary charging cable be installed in a 2002 F225TXR (pn 69J-81949-01-00) by replacing the voltage regulator with the 2003 voltage regulator. (pn 69J-81960-12-00)
thanks

Looks more complicated than that.
On the later years, the aux charge wiring comes through the "drive unit assembly" aka fuel pump driver so that's different as well.
Plus the harness... -
i wonder how the 2003 aux. circuit is wired,Comment

Here is how it is wired. It is more than just the rectifier/regulator. A new main engine harness is also needed. Figure on a grand or more, at least.Originally posted by sailorboy View Post
For a whole lot less money, time and installation efforts you can simply add a Yandina Combiner between two batteries and have the same results.

well now i wonder what is wired up... I just bought the motors and i have some sort of field spliced wire in one of the green wires between the stator and the voltage regulator/rectifier which is also the aux charging cable.... the plugs and wires got burned (no kidding) and the 16g spliced wire is also connected to a #6gComment

Looks as if a backyardigan has struck again.Comment

thanks for the 03 diagram...any chance of a 02 diagram to see the difference?
many THnanks

oh.. the link to the combiner was great , i am almost convinced to revert the previous jury rig to original factory and install 2 ...Comment

hahahahaagha
spend that jack all you wish.
however the isolator circuit is already there.
ALL V6 Yamaha since about 1990 for the US market have the isolator circuit already INSTALLED from the factory.
simply add the wire from the circuit to the battery.
or spend your jack.
find a real tech that knows how to rig Yamaha.Comment

would love some input...
diagram, schematic,,
I just bought the boat,never have owned a 4stroke, so this is a learning curve.
I have something non factory wired in/on the starboard motor (cannot see it fully until i remove the flywheel) it seem to be working. it is attached between the stator and the Voltage regulator/rectifier
my usual mechanic is swampped w/ summer rush and cannot get to my port engine that i apparently messed up by inncorrectly attaching a charger.
just need some insightComment

Yamaha data has to be taken with a grain of salt.
The 2002 Yamaha product information guide does not indicate the F225TLRA as having an isolator lead capability. The 2003 PIG does.
The Yamaha parts catalog does not indicate an isolator lead for the F225TLRA. Later F225 parts catalogs show the isolator lead.
The service manual tends to indicate that there are two outputs from the R/R but the connector is not the same as for the 2003 and later versions of the F225. Could this lead be disconnected from the other lead and be used to charge a second battery independently of the main battery? Maybe. Maybe not.
If you are going to be working on your motor you really need to get the service manual. As pitiful as it may be it is better than having nothing.

Fascinating. Both leads end up at the same lug on the starter motor?
An obvious difference here, from 2003-on, is the absence of the (mysterious) "fuel pump driver and isolator"Comment

Are you thinking that the "fuel pump driver and isolator" is in some way connected to the isolator output lead that is used to charge a second battery?Originally posted by fairdeal View Post
Here is a snippet from the F200C/F225C SM that covers 2004 and later motors. Clearly it shows the fuel pump driver and isolator.

I am.
"zoom out" a little on your wiring diagram, Boscoe
Yam shows the gizmo in two different places
in fact, you already show it in post #4Comment

Now that I think about it some more I believe that the fuel pump driver and the isolator are in integrated unit, even though the WDM in the SM does not depict them as such. Very strange combination of components.
Anyway, after many words and pictures it is so much simpler and cost effective to use the Yandina combiner than it is to fiddle with silly Yamaha stuff.Comment

indeed.Originally posted by boscoe99 View Post
I assumed it was "the rectifier" the first time I spied it; then was puzzled to learn it was not.
Its got, what, FIVE different wire connectors attached to it?
looks like a joke.
almost as amazing as the rubber tubing connected to the cowling latch.....Comment
