Won't start checked coil,switch,spark plug,fuses and wires to be sure of connection and these are not problem,check gas and it turns over but seems to not get fire this is on a 90 cc 4 wheeler SunL type
I need a wiering diagram for the sunls electrical system someone has cut the wires on it and it also has a remote for the alarm. Can someone please help me by sending me the electrical diagram at firstname.lastname@example.org

First check all the connections. Something as simple as a loose wire will cause your sub to shut down. If all connections are secure, then your coils on the sub itself may have come apart. To test, try pushing in the center of the sub as it is playing. If sound comes out, it's your coils.
check speaker conections. disconnect all the speaker wires and use one speaker that you know that works and connect it to each channel one at a time. most surround sound stereos will not go into surround mode unless all the speakers are connected so make sure stereo is in 2 channel mode to start testing. check all fuses sometimes amp fuse is seperate from power circuit and denon uses relays in 99% of thier units.
Just a wild guess but it could be fixed by replacing all your speaker wire or checking it for breaks. Look for tiny teeth marks if you have a small dog or a mangled mess if you have a big dog. Is the wire running under a cabinet or furniture which touches the ground, perhaps it's been fractured by the pressure. Has the wire been pulled out of the speaker itself or possibly the rear of the amplifier. Some speakers and amps use the old insert bare wire and twist the connector type connection. Others use speaker cable with plugs on one or each end. It's possible that the wire has been fractured or pulled away from the connections inside the plug. This would be readily apparent and certainly not visible. The only way to properly check would be with a multimeter. If you don't have one maybe a friend has got one and can help you check the wiring Another way to check is to physically put your ear to each speaker in turn (with the volume at a low level) If there is a broken wire the speaker concerned you wouldn't hear anything being emitted. When you are checking make sure that all speakers would normally be working if everything was OK.
If there are bare wires anywhere in the system make sure they aren't touching. Just a tiny filiment of wire in the wrong place will cause a warning to come one.
The last thing that it could possibly be is a damaged speaker caused by overdriving it which would overheat the voice coil and cause a short circuit.
You would pick this up when you listen to them one at a time. Nothing would be heard from that speaker. This problem would be seen by the amplifier to be a wiring problem.
So visually check all wiring for breaks or crossed bare wires. Bad kinks, wire under strain, wire with marks of being squashed under furniture etc.
Do the listen to each speaker test.
Find a friend with a multimeter to help you.
Finally disconnect all your wires, put a tag on each one to remind you which speaker it connects to and take the lot to a repair shop. It would take 10 minutes to check all the cables for continuity or failures. Get the tech to replace the broken cable with one the same length and then go home and reconnect them.
Just a word of warning. Don't continue to use them in this condition and make sure anyone else in the house knows the same as it could cause permanent damage to the amplifier. Better a simple check now than spend a fortune next month or week. Another tip, if your cables have plugs on them, always pull the cables out of the socket by grasping the plugs, not the cable.
As long as you're sure the power cord is firmly plugged in, it sounds like the protection circuitry of the unit has likely been activated. This happens when there is a short circuit in one of the connections. Check your speaker wiring connections and make sure all of them are firmly and carefully grounded (i.e. the copper of the wire touches nothing but the proper terminal, and that the wires do not touch each other). Check the connections on the speakers as well. If protection circuitry is the result of a shock or power surge (lightning, strong static, etc.), you can reset it. Turn it to standby mode, unplug it, wait for 30 seconds, then plug it back in.
In regards to your issue with your SA-AK510 turning back on most likely you have a short and/or a bad connection on the unit. So what is happening is the is a charge going to the switch that is engaging the switch again after you turn it off. Note most modern electronics do not have switches like a light switch. They have an electric relay switch that turn off and on the device when the circuit is completed.
The first thing I would do is make sure that your receiver is not still in warranty. If it is I would call Denon's support. If you are not then the first theng to check would be the fuse. I have seen a few devices over the years where the fuse clip is not connected properly and starts to arc which in turn puts a charge on the board. Also you will want to look around in the areas that get hot to see if any of the installation melted off the wires causing you to have some exposed wires.
The unit is going into protection mode. The message is a generic one and usually means that the output section is drawing too much current and has been shut down. Defective speakers can cause this, but in this case, I suspect that there is a problem in the front end that is allowing DC current to pass to the output circuits. This will cause a problem that will shutdown the system. Yamaha designs are not the most straightforward nad I would not suggest you attempt this repair without prior repair experience. Take this to a service center and request a detailed repair estimate and report the results here. Armed with that info, we canguide you further.
This is the thermal overload for the amplifier section. unplug unit and check all speaker connections for a crossed wire. After all connections are checked and are in good condition, plug the amp back in and power up. Note: the polarity of the speakers when the wires are plugged in. Use the painted line on the speaker wire as a guide for which one is positive(+) and negative (-). If an amplifier is operated out of phase for too long ( positive and negative reversed), you can damage the amp. A bad speaker coil can cause the overload as well. If it still does it, disconnect all speakers and power it up. If these remedies do not solve it, you amplifier IC is shorted and needs replaced.
