Is there a JBL radio that is a direct replacement for a Marine JBL MR15B from Prospec electronics. I have one on a Chaparral boat that doesn't work at all-dead
Yes, the yellow wire is the switched hot lead - it is typically connected in one way or another to the ignition switch. There is also a smaller gauge red wire that is connected directly to the battery (through a fuse of course). Both of these wires have to have power for the radio to work. Also the black wire has to be connected to a good ground. If all three of these wires are confirmed to be in good order (power where there should be power, ground where there should be ground and no shorts) the radio should at least power up when they are all hooked up and the ignition is on.
By no power do you mean you get no response from CD or radio out of the speakers when trying to use the radio? Should this be the case then I'd like you to check a few places.
First look to make sure the wires in the back are not broke or the insulation has somehow been negated.
Next is to check the power wires and ground wire. Look for an inline fuse anywhere between the battery and either power wires. One should always be installed to prevent a surge reaching the head unit so make sure to check for a fuse. Replace if blown with same size fuse, never bigger.
Remove the face plate and notice the reset hole (last hole on the left) Take a pen or other pointed but not sharp item and stick it into that hole and hold for 10 seconded. Then retry.
Make sure the contacts for the face plate where it hooks into the head unit are clean and don't have any grime buildup that would prevent any of the contacts from contacting.
Next you can try removing all power wires and wait for 5 minutes and re-connect. Sometimes this will also reset the unit.
Your unit was discontinued and not made for long and this may be a part of why the manual is difficult to find... for free anyway it is. I can say I don't need a manual to help you determine why the unit is not powering on.
How are you determining has power but just not responding to the on/off button? A volt meter check to the wires perhaps at the back of the radio? If you get power to the wires at the back of the radio then double check your ground real well because if the ground is good then, at that point, the head unit is bad.
If you perform all the tests I stated above and still no dice then the head unit is bad. There is no "code" for the radio so that will not be a factor. It's really a process of elimination.

Have you made sure the dock is compatible with the iPod version you have? If you are having to move the iPod around, this may be because the dock isn't built for the iPod you own.
It could also be a technical fault that the dock is loose. Take it/send it back to the shop and explain your problem.
If a boat is anything like a car, the amp's negative post should not be connected to the battery, but to the ground of the boat. In a car, the entire chassis is grounded to the negative terminal, so when you run a line from the positive terminal of the battery to the positive post on the amp, and a line from the negative post on the amp to the chassis it is a complete circuit. I highly recommend placing a fuse on the positive line from the battery to the amp. Wiring this way prevents the amp from blowing up your battery, as well as prevents the battery from blowing your amp. Hope it works.
yes i am a repair shop and i have had nothing but problems out of those units you might want to look into a different unit boss marine is a good choice
They're certainly NOT out of business. You didn't provide your model number... but if you go to this link: http://www.raymarine.com/Default.aspx?site=1§ion=3&page=166 you will probably be able to find the installation manual for your indicator (look in Legacy products, if it's older) and that will have troubleshooting information. If you can't solve the problem yourself, I can look at this myself; just contact me at drshaddock at gmail dot com
