View Full Version : PLEASE HELP WITH 600 SDI QUESTION
I have a 600SDI Renegade X. I am new to the SDI engine. I started it a few times this month,with no problems, but last week it seemed like there was a delay before I had power to start it, It has electric start. Then no power at all, I pulled the cord a few times and after about the third pull I had speedo lights and then it fired up. Since then It has no power to the electric start, and even when I pull it there is nothing, So..... I bought a new battery, had to fill it myself, and was told to slow charge it, did all that and it shows the battery is fully charged.Hooked it all back up and still nothing..nada.. Is there a secondary battery that is not kicking in? a relay? what am I missing? I am heading to the show in Milwaukee Sunday and need to pick up the part while I have the chance so all help appreciated before Sunday Morn. thanks in advance!!!

Muss, I THINK there is some sort of secondary battery or capacitor or some other device that holds a charge to deliver juice for starting but I'm not sure (there must be something for those who don't have electric start or have a dead battery). Not that it will help your problem, but for future reference.....when starting, with the kill switch OFF, hit the starter button. The gauges will light, their needles will rotate clockwise (and then return) and you will hear the fuel pump pressurize the system. Wait a couple seconds and then proceed to start it.
Good luck with your problem, let us know what you find out.

I believe it is one of your relays, I have had this happen before. My 06 SDI has three of them under the hood. Buy NAPA AR201 and replace them one at a time, they will work intermittently when they start going bad. NAPA saves you a bunch over Ski-Doo. Good Luck
Rustholio, That is where I believe the problem lies in the "secondary capacitor" or the other device that holds a charge, because even with my old battery once those lights kicked on and the fuel pump kicked on it would fire right up, but that is the problem, I cant get them to kick on to get it to that point to start it, My other rev's would not do that, If all else failed you just had to pull start it, but without that juice kicking on it is pointless to even try to start, I know I'm really not liking the way they set that up in the SDI! Anyone else know what part this is that is not giving me the juice??
also Notaboveme thanks for the relay advice, I am going to replace all of them, But I still think the problem is in the secondary battery, If there is such a thing... anyone? anyone?

There isn't a magneto (http://en.wikipedia.org/wiki/Magneto_%28electrical%29) (as used with reciprocating aircraft engines, lawn motors and chain saws) in there to provide spark on a pull start, is there?
I will be damned if it wasint the relay, and what an easy fix! I bought one at Napa per Notaboveme's advice (great advise by the way) and looked above the engine for 10 min and could not find 1 relay (that is where all other relays have been in my past Rev's) and then I popped the hood, in a fuse like box there the 3 were! and how much easier to change out! I pulled the ist one and it looked perfect no corrosion even greased, and I said no way this is the problem, I pulled it anyway, put the new one in, hit the power and it fired up instantly! What a relief and easy fix, If I only would have known before I spent the money on a new battery and charger, It would have saved me $138.00. But at least I know I have a fresh battery, and I learned a valuable lesson. Thanks to all of you for your help, I would have never knew what was wrong without your help, special thanks to Notaboveme and Craig Anderson. (can you tell I am in a good mood!) 1 final question.... there are three relays under the hood, I only had the two side by side relays in, the back one was empty, what is that for? Do I need to put one in there?

That where you can carry a spare. I don't though, I keep a spare in my jacket pocket to keep warm. Have had a relay fail or stick when it is -25 below or colder after warming sled up then stopping. Can use old one again after thawed out. Learned this the hard way on a cold night.

Glad to hear you got it fixed. I didn't think of the relay in the earlier posts, since I thought the relay either worked or didn't work. I wasn't aware they would still work intermittently when they were starting to go. I always carry a spare relay, and fortunately haven't had to use it yet!
ALWAYS carry an extra NAPA relay with you when you have a 'Doo SDI. It should say this in the owner's manual on page two. Very common problem.

Muss, glad to hear you found the problem. I have a 600 SDI Summit for my wife and ran into some of the same problems. Between Dootalk and JD's website it read about the SDI dilema. Being a past mechanic (paid my way through college by being a ceritfied mech)I started to explore "why" the SDI had these problems. A good mechanic will give you a "cause & affect" of a failure. If they can't they are just part swappers. Now these relays have been around for years. In off road lighting, snow plow set ups, all kinds of auto and marine applications, etc... I am not postive but I believe they are used on the lighting and engine of the BRP groomers. Why are they failing in the SDI. I decided to take a weekend and take my wife sled down to look things over and analyze what could be happening. The relay was designed to take a small amoun energy from the electonic control management system and open a circuit for a more powerful circuit within the ECM system or externally (fuel pump, lights, etc...). They quit working if:
The power supply for the exciter circuit is incorrect.
The power supply for the main circuit is incorrect.
The relay develops moisture and corrodes.
Through use, the contacts in the relay wear out.
And if there is electical inconsistancys in either circuit going to the relay.
Everyone was on the money with cleaning connections and using grease. This cured most problems but I found more. I beleive ground leads were more to blame than anything. Alot of people talked about the battery cable and the dragon tooth washer had to be on the footwell battery ground lead. Correct but I don't think many checked the other grounds. Like the wiring harness ground on the frame under the guages. I found my self tapping screw ,that SkiDoo uses, had become loose. tightening it up cause the cut threads in the tube frame to strip out. I thorugh drilled it on the frame (with dragon tooth washers, bolt and nylock nut, and grease). I also found a couple wires with just a small amount of chaffing. Enough to cause electical inconsistancys. Nothing that was life threatening to the sled but enough of them combined to cause alot of problems. I'm sorry if I'm long winded but I don't want you to think everything is cured and then get out on the trailer and develop problems you thought were cured. Look your sled over. SDI's are awesome but they had a few small, what I would call, assembly line issues. Good luck and feel free to contact me if you want.

Doo Dr has an EXCELENT point. I found the same problem with my SDI. The self tapping screws that hold the voltage regulator to the bulk head were loose and stripped when tightned. The ground wire is attached to one of those screws as well. I think that is why my regulator went bad. Because the regulator went bad, causing heat to the electrical system, my plug connector from the regulator overheated and went bad, causing intermediate loss of electrical power. Very frustrating to find that problem. Sometimes I had no power to anything, mainly after riding a while. This problem also took out a relay. I also drilled the holes out and used nuts, bolts, star washers and lock tight.
Check those grounds!!!

Sounds like you should go back to the Massey Ferguson.
