I am putting a 02 Daytona motor in a 99 Sprint RS body. Everything fit and hooks up fine except the alternator, where is the alternator, I know the 99 RS has an external alternator and I dont know where the hook ups are for the alternator on the Daytona. Also, does the Daytona have a regulator and if it does what does it do?

I didn't know Triumph made an RS in '99.

hi cklassen, the alternator is 'inboard' on the LH side of the crankshaft (and about time!). Pickup located there too. Starter sprag on the RH side.
Sounds like a good project cklassen, post a pic if you can
Cheers

edited as forgot the regulator/rectifier. on the '02 Daytona was located on the frame at the rear RH side. An after market should work fine. The 'old' alternator contained the rec/reg unit internally. Do you have a wiring diagram, you will possibly need it to navigate the charging system due to the component changes.

Oh my bad..duh..its a 00 Sprint. Thanks, for the info. I think that the alternator is the only thing I am going to have trouble with when it comes to "rigging" stuff up. Oh, and the exhaust system, but other than that it has been smooth sailing. On the wires coming out of the crankshaft, (which i know are from the alternator) they are all grey, (there are 3 of them) would that mean that they all do the same thing, like positive charge? Because if that is the case I can very easily hook them up.

On a completely new topic, I know in 02 or so they went to a open loop fuel injection system, (I believe it is where there is a sensor in the exhaust) and it changes your fuel air mixture when you drive, since the RS is a closed loop system, could I just leave that sensor unhooked, or how would that work?

What is a regulator? The only reason I ask is that I saw one on ebay for a Daytona, and the RS doesnt have one. I just dont know if i need it or not.

Also, the CDI box on the RS is the same as the 02 Daytona, but it has been programmed for a RS-955i motor, is it possible to run the daytona motor with that configuration just long enough to get the bike to a dealership so it can be remapped?

Thanks,
John

You definitely have to have a voltage regulator somewhere in the system. It keeps from overcharging the battery when the revs come up. On the RS it is inside the alternator.

I have shop manual for my '01. I'm not sure how to scan and send the wiring diagram to you.

Thanks for the info, on the scanner stuff I have no idea, I guess you would have to send it to my email. But I dont know.

Hi again cklassan
To answer your 1st question: the 3 wires from the alternator you say are grey will connect to the voltage regulator/rectifier you saw on Ebay and need to bid for! :hammer:
As I said in my earlier post. the regulator/retifier unit is contained within the alternator on the RS engine. The '02 Daytona has a unit mounted seperate to the alternator, and mounted to the rear of the frame on the RH side. You will need to mount the same unit to hook to your '02 alternator. The reg/rec unit benefits greatly in terms of reliability if mounted in an area of air flow.
As for wiring: the 3 grey wires(usually yellow) go to the 3 black wires on the reg/rec unit. The 3 black/white wires from the reg/rec unit go to a good earth. The 2 black/red wires be connected together. then run as a single wire to the main fuse. Connect it to the 'power out' side so that its fused to the battery.
Your next question:what is a regulator. It is basically a solid state current coverter and voltage control unit rolled into one. the job of the reg/rec unit is to convert AC voltage (alternating current) to DC voltage (direct current) for the battery. When a pre determined voltage is reached excess charge is unloaded to earth being again converted to heat. The body of the unit is in most cases heavily finned to assist cooling.
Your exhaust question: the O2 (Lambda) sensor you refer to allows the '02 to run a very lean ixture at idle and light load throttle opening. Both you RS & the '02 Daytona run a Sagem MC1000 ECM. You wont have to concern youself with it. "Closed loop" mode activates at an air/fuel ratio of 14.5-14.7 :1
Recoding and tuning: The '02 Daytona code for your new engine with std exhaust is 10178. If you have an aftermarket exhaust 10181 will do well.
However, both these codes contain the lean fuel condition at low load and idle. The idle may even be a bit rough. Two solutions: 1, load the tune and adjust the idle trim to a value of around 13.5-14 :1 via the dealer.
2, find a local TuneBoy 'Doctor' & dyno for massive results.
Be prepared, the RS wont wear many front tyres when you're done!! and you'll suffer from big grin syndrome

Finally, the exact date of manufacture is stamped on a small raised cast block near the sterring head.
The exhaust cam shaft out-rigger bearing has the engine manufacture date engraved on it.
Cheers and good luck, keep us informed

Wow. that helps out tremedously. I think I should be able to get everything running correctly once I recieve all of my parts, but on a regulator, should I get a factory one or a other brand? And you said hook the wires up to my fuse box, should I do that or just hook them up to my old alternator wires, and then let them go through the fuse box or? And on that sensor in the exhaust I just leave it unhooked, correct? I think that pretty much sums everything up for me, but there is always the possibility of something messing up.
Thanks,
John

Hi John,happy to help with your progress.
The Regulator you require would be best purchased S/H from ebay or a good breaker. Will cost about as much as a SHINDENGEN 35amp unit new.
The unit is a good match though, as the RS is not equipped with a 'charge' light on the dash.
Must apologise John, I mis-read your earlier post, you do indeed have the Lambda sensor in your exhaust.
This is already connected to terminals 2/F1-1/A3-1/A2 of your ECU. With the 10181 tune code down loaded your engine will automatically run in closed loop mode.
Good point about your alternator wires John.
Referring to both the Haynes manual #3755 covering your RS loom, and the factory manual #3850595 issue 3 that covers the '02 Daytona loom:
One black wire from the RS/alt goes to a Blue/Yellow wired fuse that is on the headlight cut off circuit.
This cuts the headlights during start up to allow full voltage being available to the starter and ECU.
The other RS/alt wire goes to the ignition switch/main fuse circuit.
The '02 Daytona is wired differently to achieve the same function.
Simply, you can do the following:
All three wires from the '02/alt go directly to the new Reg/Rec unit.
The two original RS/alt wires can be connected to the two output wires from the the new Reg/Rec unit.
The two earth wires on the unit to common earth.
Looking through the diagrams I see that the wires can differ in colour, best you get the unit you'll be using 1st so I don't confuse you with too many wire colours.
How about the air box John?
Mounting to the cam cover differs, but the stepper and inlets should line up ok. You may be able to chnge the mounting brackets over, really not sure on that at all.
Are you using the '02 stick coils? The RS ones won't fit.
Cheers

ckassen

Well I am going to have to get some new coils, probably just buy some off a wrecked bike; its just a matter of finding them. I will decide which air box I will use once the throttle bodies come in, the only reason I dont want to buy a new box is because of the position of the sensor on the 02 air box, the connector from the RS harness isnt long enough, although I could just split them and add some more wire, I figure I can just wait and see how everything fits. You are right, the mounting does differ, but I am just going to decide what I will do once some other stuff comes in and I get it all figured out. Do you know if the exhaust headers for all of the 02 models are the same? It is just because I found some headers off of a 02 Sprint and am wondering if they should fit on my motor, and if I can hook up a 02 Daytona aftermarket can. Speaking of exhaust cans, what would be the best "bang for the buck" exhaust system, preferably a LOUD one. But anyways, almost all all of the wiring is hooked up except the alternator stuff, I just have to ground out a couple of things, but other than that it should work good. On my wiring harness I have 2 connectors that wernt connected to anything, they were wound up and were just there not doing anything, do you know what they are? Oh and I have to get a new oil cooler and connecting lines (the motor didnt come with any, but other than that and the exhaust it should be smooth sailing. One other thing is that I dont know if the connectors that hooked up to the coils on the RS will hook up correctly to the coils on the Daytona, I just dont know if they will match up, or if I will have to do some custom stuff.
Thanks,
John
