2013 Nytro XTX not Charging... out of ideas.....

[sehughes]

I have a 2013 Nytro XTX with about 200 miles on it.

After running the sled for a while it shuts off due to low voltage.

I have replaced the battery with a new one that works and test perfect.

I have tested the output of the stator ( 3 white wires) and when I test between any 2 of them on AC Volts I get 40+ volts at idle.

I have tested the output of the voltage regulator and it has over 14V DC at idle.

When all connected I have 12.8 V at the battery whether the sled is off or running. I have tested from and idle to 5000 RPM and no change.

If I do a continuity test on the battery connector for the voltage regulator I get good connection from the red wire to the positive terminal on the battery.

On the black wire I do not get connectivity between it and the negative terminal or any other ground on the sled.

What confuses me is that is I measure voltage across the plug for the voltage regulator I do get the 12.8v battery voltage even though I cannot get connectivity from the black wire to ground.

Is there something like a diode inline with the ground wire n the output of the voltage regulator?

All fuses that I have tested on the side of the battery are good and there is not a single sign of corrosion on any connection I have looked at on the sled. Everything looks new as it should for having less than 200 miles.

You should see continuity between the black wire and ground or the black wire to the battery ground. The regulator black wire should be grounded to frame can you see where its grounded to frame and that it is a good connection. Have you looked closely at the plug from the regulator to be sure its not broken or not making a good connection? #1 in picture is regulator and #7 is battery and you see both show grounds. Start tracing until you find a break either in wire or plug.

Good luck

I have checked that the plug for the output of the regulator is good by testing for continuity from the pin to the wire on the backside with a thin probe I have that pushes though the wire.

The issue is that I have no continuity to ground on the black wire but I do have battery voltage (approx. 12.8) across the red and black within the plug. This makes no sense to me as that shows I have a ground.

I have about 2000Ohm resistance from the black pin to ground on the battery or ground on the chassis.

I do see where the battery ground connects to the frame beside the engine and there is a tab that looks like a possible second connection on the other side of it that is bare. I am unable to see any disconnected wires. It is hard to see with my supercharger and intercooler filling up most of the space.

Does anyone know where the black wire from the voltage regulator makes its connection to ground????

You should be close to 1 ohm to ground on the black wire to ground. Something just seems wrong with that wire. Possibly partially broken inside wire.

Agreed, But even if it were partially broken a continuity check would still work. If I check voltage across it I can pull, push and twist the wire and it does not break connection.

Knowing where that wire makes its connection to ground would be a huge help.

Sounds like the regulator is not making a good ground. Disconnect the black wire and wire brush it and the chassis connection, reconnect and see if it now has continuity.

I am trying to find out where it connects to the chassis. All the wiring goes back under the intercooler towards the engine but I can not see where it goes. I do see where the battery makes its connection to the chassis.

If you get desperate you could consider cutting it and making a new chassis ground point.

I was hoping to not have to do that but I am thinking I might need to.

OK so I have it fixed and I am not happy.

It was a broken ground wire. This ground connects on the left side of the engine compartment and was tight.

I was able to see some cut tape on a wire harness in the area above the primary clutch. once I peels the tape back I was able to see the ground wire broke in 2. There was also a brown wire partially cut through.

While I would have been fine with this being just a wire that worn through what I found next is what really pissed me off. There was another wire next to these in the same bundle that already had black tape around it. That tells me that someone caused the damage to these wires and only fixed the one. Only the dealer has worked on this sled to install the supercharger so I am thinking it was damaged then. I have had some electrical issues that caused me to not ride last year much and I am sure this was the root cause of it.

There is no reason a sled with less than 200 miles on it should have cut wires.

One I repaired the ground wire and started the sled I had over 13V at the battery.

That's great you got her fixed! That's what I figured was wrong broken wire! Now go out and have some fun.

Just because you took it to a dealer, doesn't mean everything was done correctly. My MPI Apex, I bought used, and the previous owner had alot of work done to it at a dealership, and I found alot of stuff wrong with it when they installed the drive cogs. Chaincase was completely screwed up. Friend had his bearings in chaincase replaced by local dealer, they fuked up and bolt backed out, rubbing completely through the case. Moral of the story... Learn to work on your own stuff if possible. 99.9% of the time, i work on my own cars, bikes, sleds, anything. If something goes wrong, it's my own damn fault, instead of wanting to rip off some 18yr old kids head at a "dealership" for screwing my stuff up.
