Mitsubishi Altenator and regulator /swap to Delco/ HELP!

[Lebby]

First time for posting new thread. Please bear with me. OK?
Just recently took delivery on a Satoh Bison. Has a few problems here and there but getting most of them straightened out. I hope anyway. My current dilemma has to do with the wireing. Somebody in the past rode this Buffalo hard and put him away wet.
Prior to me purchasing this tractor, the previous owner? did some major cooking of the wire harness. Wire colors for the most of it are still recognizable. The original Mitsubishi altenator has been replaced with a Delco which I believe is a 10SI. (Brief description: Says Delco - has one "Bat" terminal - has one "Grd" terminal - has a rectangular port with two plug in wires. Port on my left is stamped with a "R" and has a yellow wire coming from it. The port on my right is stamped with something that resembles possibly a small star. It could be some letter but I realy cant tell for sure. There is a green wire coming from this port.
Ok I'll take a breath here...
Attached to the side of the altenator is what I beleive is the new regulator. (Brief description: Stamped tin filled with an epoxy of some sort. Is approx. 1 3/8"wide x1 7/8" long x 1/2" thick. Under neath is a tag that states: Transpo - D7014 /12 volt- 241 The yellow and green wires come out of this and are plugged into the altenator. Also a black wire that attaches to the "Grd" terminal on the altenator. A faded red wire that is attached to the "Bat" terminal on the altenator. Last but not least there is a stubby orange wire protruding from the epoxy that has been capped off.
More useless information to consider....
Tractor charges well (14.5 volts), lights are bright and keeps the battery fully charged.
Have preceeded to check out all of the wireing per Satoh S650G wireing diagram. While doing the traceing of the wires I discovered that:
1. The old mitsubishi voltage regulator was still somewhat hooked into the sytem. The six attached wires under the Mitsi regulator had fried most of the insulation off. There was a small amount left so I could identify the color code. Four wires were cut off just short of the altenator. These were taped off and tucked into the wiring harness. These were the wires for the E-N-F-A tabs on the old altenator. I would guess don't need them with the new setup. The larger black-white wire which fed from "Bat" terminal on old altenator to "B" post on starter switch was also cut off and retaped. It had a major melt down. This is still hot probably not hurting anything.
2. The yellow-green wire runs thru/to the "L" tab of the volt. reg. this I believe is for charging lamp. I beleive this is still working properly. The black wire feeds in to the "IG" tab on the Mitsi regulator. This is fed by voltage that comes from the "IG" terminal on the starter switch.
3. Voltage for the system comes from "Bat" terminal on altenator and feeds into large (+) terminal on the starter.

Almost done here...
I would like to get rid of all the extra, melted wire and old Mitsi regulator as possible and replace with a newer wiring harness.
Last question/s here:
I would like to eliminate the old regulator. If I do this I will have two wires left over and not sure how to incorparate them into the new system or if I need them. These would be the wires before mentioned in #2.
Once again thank you for your patience and thank you in advance

Wow....it's over my head. I would either send TBN member mitch becton ( REALLY good alternator specific guy) a PM and ask him if he could offer any advice OR post this in the Mitsubishi specific forum here on TBN. Tons of Satoh owners there and someone has probably been down this road or knows enough about it to answer your questions.

gm made 2 types of look alike alts .. for gassers ( with multiple case mounting ears for different motors )

one had BATT- grnd -, small connectors - R and -F... used an external voltage regulator

the other one was SI batt grnd , small connectors 1 and 2 .... had an internal regulator

thanks for the kind words darryl what you have is the 10dn external delco alternator is last one made by delco external regulated. the d7014 attached by thru bolts of alternator and made it be self exciting by eliminating old style external regulator. the wiring diagram for what you have is black wire is ground B- the orange wire controlled the light if applicable the green and yellow should be in a molded plug green is the field wire and yellow was attached to stator the red wire is positive of course if you wire this accordingly you can eliminate all the original wires i feel it was left there but should not be operationable reply with any question maybe this will help understand the wiring of this any old wiring can be elimanated

Thanks to Daryl, jaotguy and mitch becton!

It is truly a great day when you can learn something from everyone that you "talk" to.

Daryl... you gave me right direction to look and you were the first one here.

jaotguy.... the breif description of the two different altenators was good. Looking closer at the two letters embossed in the casting there is the "R" and the other one does indeed resemble an "F". And to make lite of the situation, you mentioned about the different mounting ears for different motors? Mine was actualy "ground" some (with a grinder) and then mounted upside down. LOL. It works! Who can argue.

Mitch Becton... Your above info was great and with it I should be able to put a few more of the peices into the puzzle! ' probably be a few days before I can put this all back together. Will keep you'll updated as to progress. Right now there is plenty of white stuff to shovel. And then there is the matter of that jolly old fat guy in a red and white suit that keeps stumbling around here. Not that he's in the way or nothing...

Thanks to everyone and have a Merry Xmas and a happy new year!!!

Man oh man where does the time go? One month later and I (We) have successfuly completed this project. Pertaining to the two mystery wires mentioned earlier, I connected the yellow -green wire to the stub orange wire coming out of the Transpo D7014 regulator. This connected the circuit for the battery charge warning lamp. The larger black-white wire that was cut off I reattached to to the output stud on the altenator. I removed the old Mitsi regulator. Started it up. System was charging at 14.2 volts. Turn on the head lights flood lite and flashers and still charges at 14.2 volts.

Success!!!

Thanks again for all of your help.
And a special thanx to Kernopelli ; jaotguy ; mitch becton
