Fusion MS-RA200 head unit will not turn on

The +12v constant and switched have power and the ground is hooked up. I checked the 15amp fuse on the back of the unit and it was fine. Any suggestions?

Amp want power off


Hello
If your Dual Car Amp refuese to switch ON check the following.
+12V wire is not connected or incorrect voltage.
REM wire is not connected or incorrect voltage.
Ground wire is not connected.
Fuse(s) are blown.
If the fuse blows repeatedly, check whether the +ve voltage wire touche the chasis of the vehicle. If it is OK, the fault is with the univt itself. That is, the output of the unit has a short. Check for any output IC failure. OK.

Will my b4 250.0 work with out hand held remote?


Absolutely. Any car amplifier needs only 12v constant power, Chassis ground, and a switched 12v source to power up. Your switched source is most commonly from the remote turn on lead that comes from your head unit.

I have just put in a new cd player in my 1991 nissan pulsar but i think i have blown a fuse as the cd player light comes on but doesn't actually turn the cd player on. I cannot find which fuse it is as all...


Sounds like you have a constant feed going to the head unit, but the accessory wire on the head unit is not connected to an accessory 12v.
Are you using an aftermarket wiring harness or fishing through in-dash wires?

If you really want to check if there is a fuse blown, unhook your head unit and briefly touch the 12v accessory, 12v constant, and ground to the battery of your vehicle. If your head unit comes on, you have found your culprit of one of three wires.

Power problem


The best places to look are:

1. Remote wire running from fuse box or back of head unit.
2. Ground wire, make sure it is connected good the the body of your vehicle. (I almost threw away and $700 amp because the ground wasn't secure enough).
3. If equipped, inline fuses on power wire or connections on battery.

If all these check out, then its probably a short inside the amp. You can have them fixed, but sometimes it cost just as much for a new one! Hope this helps and good luck!

I have a jl 500/1 . The distribution block is lit showing 12v plus. no green power light on the amp? I disconnected pwr and ground and reconnected. the green light came on for 10 seconds and shut off. all...


The amplifier will not power on unless/until it recieves the turn-on signal from the head unit.

It seems the issue is with the head unit in this case.

Check the fuses and verify constant and switched power with a multimeter.

Once the Head unit powers on - the amplifier should also.

I need a fuse diagram for 2001 Nissan Pathfinder


Do you want to install a new unit or wht ? u may use this reference to work upon ....
Get yourself a digital multimeter. Find the +12V constant, 12V remote, and ground. Connect them to the new head unit. For speaker wire get yourself a 9V toy battery and listen to poping noise. If you have a factory amp you need to power up the factory amp. Use the wiring diagram below to serve as a guide. Test your wire first before connecting them.


NISSAN
P o w e r
Memory (+12v Constant) Red
Ignition (+12v Switched) (varies) Brown or Green
Ground (-) Black (varies - most don't have one)
Illumination Red/White

Power Antenna Green
S p e a k e r s
Right Front (+) Brown
Right Front (-) Brown/White
Left Front (+) Black

Right Rear (+) Blue
Right Rear (-) Pink

No power


Yes the yellow needs to be connected to 12v power but so does the red one....the red is for when you switch the key, (switched power)..if u want to test it then hook yellow and red together and hook to a reliable 12v source.....then properly connect the black to a good ground....if it does not power then the radio is bad....if it works then it just needs to be wired properly inside the vehicle......yellow is constant, red is switched, black is ground, blue is accessory switched, and the dual ones are for speakers...i hope this is helpful...

Wiring problem with cd player and lights on car


If the unit is turning off when you turn the headlights on, check that you haven't used the illumination wire as ground.

The illumination wire will normally measure as 0V compared to chassis ground. When you turn the headlights on it will go to 12V compared to ground. With the headligts off, if you measure your constant power and switched power (aka 'Accessories') lines against the illumination wire you'll measure 12V and everything will seem alright. However, if you turn the headlights on and then measure again (now that the illumination wire has gone from 0V to 12V) you'll measure 0V, since the voltage difference between the 12V constant/switched power and the 12V illumination wire is zero - they are both now at the same voltage and no current will flow.

Once you find (or install) the correct ground wire and you should be right.

Installing CDM-7836 into a Boat


Yes I can help, the blue/white wire isn't meant for that purpose. That wire is meant for an amplifier turn-on. the wire you want to use is the red that is the accessory lead. What I would recommend is finding a constant 12V to hook to the Yellow and hook the switch 12V to the red. This way your radio will retain memory. Or you can connect both the red and yellow to that switch and never turn the switch off. Simply use the on/off button on the radio. Good Luck I hope I could help.

Nothin will work


If you've got 12v constant on the yellow, 12v switched on the red, and chassis ground to black, your fuses are good the radio is powered properly.

When you plug the harness into the back of the radio you should hear the CD transport cycle. That's telling you the radio's getting power. Hit the reset button (pin-hole switch on front panel) and hold the small square open/close button for 2-3 seconds.

If still nothing, the radio needs service. I'd send that model to Alpine in CA for repair.
