There is no fuse on this amp. It requires EXTERNAL fusing, as it is a PRO amp.
There are diagnostic LED's on the board if you look inside. They may point you to a problem, but the odds are the amp is shutting down because it is detecting a problem. You need to take it to a repair shop for an good tech to fix. Unless you are VERY into electronics, and very knowledgeable about the operation and repair of car amps, I would not attempt to repair it yourself. It is a very nice, expensive, high power old school amp. The power wiring needs to be sufficient as well. This amp will draw ALOT of current at full power. (80 amps or so I think) there's manuals for it floating around the net with the exact specs needed for the external fuse).

Cruise control doesnt work the light doesnt even come on

Fuses are a great place to start, if not fuses the actual cruise control switch may be to fault. Rear heater do you get heat out the front and if so is there a fuse for a rear fan maybe a blower.. Let me know

The fan on my 06 gxsr 600 comes on when i crank it but then goes right back off an will not cool my engine I have checked the fuzes and they work what else could be the problem


The fan should not actually come on untill the engine goes over a temprature set by a thermostat,
when riding around normally the fan doesnt normally come on except when you are waiting at traffic lights or staying still,

You can test the thermostat just start the bike and let it idle the fan should start between 80degC and 90 degC if the engine temp goes over 110 -120degC and does not kick in there is definately a issue there with the thermostat, it doesnt sound like the wiring, fuses or relay as it runs for you sometimes.

Hope this helps:)

Where is the headlight sensor or fuse?

the light sensor is located up under the black plastic cover around the rear view mirror mount. from the outside of the vehicle, look at the rear view mirror area. you should see a purple / blue square (2" x 3") that is the rain sensor, right beside it should be a small clear round circle this is you light sensor. in the day light with the car running, place a dark piece of tape over it and you lights should come on. as far as the fuse goes...sorry don't know.
hope this helps

Heater fan isnt working. cant find where the fuse

Look in the fuse/relay box under the hood,on drivers side,if the fuse is not blown,check for a bad relay near the blower motor,or in th relay box.If all this checks out,it can be the control head,it is a system with sensors all over the place,and any of them can cause the problem.But it does sound like the control head.

Ac quit running,compressor doesnt run,fan doesnt run,no bad fuses or relays that i can find,replaced controls

It may be your ignition switch. Bang on the bottom of your steering column with the key in the "on" position and see if the fan will fire up. My car is doing the exact same thing right now, but I can basically rub the bottom of the trim under the steering column and it comes on. It will also start when I hit a good bump on the road.

Good luck!

Cooling fan won't come on, have tested fan and replaced temperature sensor.

First question to you is.. Have you checked the wiring or ECU codes?

check the cooling fan switch on the back of the block, unplug the connector and jumper.
2 wires, turn ignition on and fan should come on...

if it does-----replace the cooling fan switch
if it doesnt----- go to the cooling fan relay on the pass side inner fender
panel behind the headlight and check it, besides the fan itself and the fuse, those are the only things in the system.
