Ericson 28 factory Wiring schematic

While reading through the posted E28 manual there is mention that during boat production wiring was pre-installed for a stereo aboard.
Chapter 5 page 3 section H. Stereo.

The Ericson 28 was planned with pleasure and comfort in mind. a very pleasant addition to any complement of accessories is a stereo radio and tap player. its installation has been made much easier by pre wiring leads to the forward main cabin bulkheads fro speakers. Consult wiring diagram for leads.

I' was unable to find the aforementioned “wiring diagram” any one have prior experience with searching for and finding these wires. Does anyone have this diagram? I have a 1990 E28.
another thing has anyone else noticed that you cant search with numbers on this forum? if i perform a search for 28 search returns nothing yet i see countless posts with 28 in the subject.

Thanks!
Jesse

I looked at the E28 documents available on this site and couldn't find anything with actual pictures of the interior. Does your boat have any kind of nav station area? If so, there may be a removable panel where VHF, stereo etc. can be installed. Look behind that panel and you may find the wiring you are looking for and it might even be labeled in some way.

Here is a pic of my nav station:

The panel where you see the VHF, Stereo and handheld VHF is removable.

Thanks for your reply the unfortunatly the e28 does not have a nav station. Panel is on Starboard side

I'll just pop the panel out and see if there are wires back there if there are then i'll go hunting for the other end.

stereo wiring

I have the same layout as your's (no nav table).
My stereo is mounted just above the double doors inside the storage compartment that is visible in your picture.
One of my speakers is not working (and the stereo unit is probably 20 years) so I need to get in there and check out the wiring. If it looks 'factory', I'll let u know.

Jesse - FWIW, the wires to a stereo should be color coded blue-white (+) and black (-). No guarantee, of course. You can look at the terminals on the breaker to see the wire color, or if there is a wire. Nothing else should have blue-white wires.

Great idea putting in cab. I bet a blue tooth or rf remote might even still work through the door for sure not one with IR. I'll have a look for the white and blue wire. Thanks again

Jesse - The blue-white wire is blue with a thin white stripe. It's quite different than a white-blue wire.

Jesse, My 1989 e28 has the radio head just aft of the main elec compartment over the quarterberth. Boat's in the water at Montrose Harbor if you'd like to swing by and have a look.Jim

My E28 stereo installation

I don't know if this was installed by a previous owner, but I like the set up. It sounds nice. Mine is a 1986 E28.

Chitown;

I also have a 1990 E28, coincidentally I bought it near Chicago. I installed a stereo in mine last weekend and the boat is prewired. My panel looks identical to yours. It has a 12 volt breaker labelled "STEREO" which I used for power. There are speaker wires pre-installed, they originate behind the 12V or 110V panel (not connected obviously) and they run to the bulkhead on both sides of the boat. If you open the sliding cabinet in the head, and look in the aft corner of the upper shelf, you will see a coiled speaker wire. That is the right-front in my installation. If you look in the port side hanging locker at the upper fore corner, you should see the front-left speaker wire coiled there. I installed Polk Audio Atrium 4 speakers against the bulkhead on both sides, facing into the cabin. The supplied brackets fit perfectly in the upper outer-most corner of the bulkhead and the speaker wires feed through in the right location. The bracket allows the speakers to swivel. I installed a Clarion CMS 1 head unit behind the hull liner to the left of the 110V breaker panel. It fits in there perfectly. I then installed the wired remote control on the liner just to the right (aft) of the breaker panel. I installed an MB Quart ipod socket there as well. I am also going to install Sirius, USB, AUX and TV audio inputs in the near future because the head unit supports all of those inputs. I installed a Shakespeare 8ft. whip on the transom on an old Loran C antenna mount which was no longer in use. I can take pictures of any of this for you if it will help.

Would love to see some pictures of your installation.

I need to upgrade my stereo (audio tape stereo system probably 20 years old) next fall/winter/spring and I am looking for some installation ideas

Thanks

Thanks for your response. I'll have a look this weekend i did find wires labeled behind the panel just didn't know where they terminated on the other end.
at the moment my box speakers are resting in the starboard shelf. I haven't had the heart to put screws into any of the teak until I am absolutely sure where I wanted to install them.

FWIW, I have recently discovered the original wires on my 71 E29. They were actually embedded in the fiberglass! The stub ends are still sticking out where the original light fixtures & etc. were located. Of course, there was no stereo option at that time.

Here are the pictures of my stereo install. First pic shows breaker panels and new additions to the right of it. I may make a panel, in the future, that looks like the breaker panel and hinges down to give access to the back of the new electronica. Second pic shows the clarion source unit tucked in between the 110 volt panel and the cabinet to the left of it. It fits perfectly in there. Third and Fourth pictures show the port and starboard installation of the speakers, as well as our hats and cereal preferences. The factory speaker wires were right behind the bulkheads in the head cabinet and the hanging locker. The fifth pic shows the 8' Shakespeare AM-FM whip antenna. The mount and cable gland were already on the boat from the Loran system that was installed at the factory, it's really nice when you can use mounts and holes that are already on the boat instead of drilling new holes.

Aquavit, a name that may change to "CORPORATE FUN$" in the future.

Some nice looking installs here. I was wondering about what people did for am/fm antennae. In reality, I never actually listen to radio, but it bothers me to leave it disconnected. I was thinking of some kind of splitter on the VHF. Also wondering about power consumption on some of these high-end stereos.

I recently made up a hinged panel for my radios, similar to those breaker panels. The only problem is that with all of the cables connected, there is insufficient clearance to actually hinge it open. I have to slide the stereo out of the panel to open it, and hence, have to keep those two little slider tools that come with it handy. I'm afraid they'll get lost at some point.

Why did you put that style VHF antenna on the stern rather than one on top of the mast? I would think the low position might limit your range.

I put one of those Shakespeare VHF/AM/FM splitters on my VHF antenna cable and it doesn't seem to work for my FM radio. (Or maybe I'm not tuning in the local stations correctly...) Don't recall if I have checked the AM band as I also don't regularly listen to AM or FM when sailing; mostly CD's or Sirius Radio. The splitter does not seem to affect the VHF signal, however, so I have not removed it. I can usually reach Newport Beach (weakly) from the Santa Barbara Channel and can receive Coast Guard transmissions from San Diego.

My stereo unit used to have just an automobile-style metal antenna plugged into it and hidden in the headliner on the starboard side. That did work, but it was all rusty and ugly so I removed it before it discolored the exterior surface of the headliner.

The PO of my boat put an 8-foot fiberglass antenna on the stern for the VHF. I guess he didn't want to climb the mast. I haven't removed it yet, only because I wasn't ready to patch the hole. I suppose I could keep it for a backup and plug it into the stereo.
