When hooking up a JVC KD-S36 AM/FM radio to my electric 36 V golf cart the radio will not turn on. I have power going to the red and yellow wire, and all the fuses are good

Ok, just so I get this right. You want this unit to power up, without hooking the 2 power wires??? Red is constant power, yellow is switched power. Did you use a wiring harness to hook the radio up or did you hard wire it? I alway recommend a harness. This would make the install easier. If the unit works witht them wired, use it.

The yellow wire (constant) is for functions such as clocks, retaining fm stations, etc. The red wire (DC power) is what runs the unit. You said this is going on a golf cart right? But you say you don't want switches and don't want it to drain the battery during storage. Well, you can't have the best of both worlds. If you don't like the visual of a switch in the open, at least put one close to the battery under the seat. That way you can switch it off in storage. The switch would go to the red wire. You might even think about switching the orange wire if you expect to keep it in long term storage. the dimmer wire usually hooks to interior light controls. Like when you turn your lights on to drive at night, the radio won't be so bright inside, but in the day time, it will be. This is not a necessity. Happy wiring

The yellow wire is most likely the memory wire as it needs to be connected to a constant 12 volt source.

"Hook red wire to to acc fuse" means you need to hook into the fuse block under an Accessory Fuse. (ie: something that can't be turned on unless the car is running or the key is in the "Accessory" position)

The red wire is explained above. It does not connect to the harness.

Just remember that the yellow wire needs to be hooked to a constant 12 volts and the red needs to be hooked to a circuit that is only active when the car is running or switched to the "ACC" position.

blue/white is amp remote turn on, red is ignition (switched hot pos.), yellow is constant hot, and black is ground (neg.)

hope it helps

you have the red and yellow wire on the radio mixed up switch them

Connect Yellow to Battery (always 12V), red to ignition, and black to ground. Disconnect all others. Check it. If the radio stays on and plays CD, then radio is good. You may check other wiring

bro to me it sounds like your radioi is bad you got everything hooked up right to get sound from it maybe the ant. hooked up but you should still get sound thats why I say the amp in the unit is bad!
here a little help: red: ignition when the key is turned on
yellow or orange: all time 12v
black: ground
blue: amp turn on, or auto ant.

sounds like only the constant(yellow) wire has power. you need to make sure that the switched wire(red) has power as well. good way to trouble shoot, is to hook the red to the yellow to see if it powers up then, if so you know the radio is ok, you just need to find a better power source for the red wire. hope this helps.
