J&m Cb Install

[epoche]

Have a friend here in Green Valley, AZ. who is coming over Saturday to help me install a J&M CB system; including the install of their high end speakers and mic in a Shoei RF 1000 full coverage helmet.

My question is where in the left front end would I best tap in to a switched circuit, without disturbing OEM workings?

I used the headlight relay which is on the right behind the instruments for mine.

You can get power off the left front running light

The instructions say to use the tail light circuit. It's not in the front end though. There is a noise filter that comes with it in the power cord. That was the way I installed mine & then later the integration module. I don't have any noise issues. Good luck whatever you do.

There is a switched circuit on the right front for the windshield auto-retract that is easy to get to, just above the right lamp. Look for a two-circuit white connector.

I added two bridged screw blocks for switched power (through a relay) and the other for common ground (back to the battery). Keeping everything tied to a common ground can help prevent noise in your audio systems.

Thanks for all your speedy replys. The J & M stuff will be delivered tomorrow, so I'll get better idea what I'm dealing with; although I did download the install PDF file from J & M and it says just connect power from any switched circuit. I'm getting the unit from Sierra-mc.com as their pricing is 15% below J & M directly--no Arizona tax and modest shipping $12.

Not clear to me how an inline relay would help noise suppression. Any clues there?

Good choice, I got mine from Sierra too.

The relay is to ensure the source has enough power, The running lights may be fused too small.

The unit comes with a filter to help noise suppression.

How/where did you hook-up the antennas?

How/where did you hook-up the antennas?

I used this:

SIE-CBA-FB24-BNC.

Details

SIERRA 24" FLAT BAR MOUNT ANTENNA FOR LUGGAGE RACK / TOUR TRUNK - PL259 TO BNC

Price: $60.00

and mounted it to the Yamaha trunk mount.

Oooooh! Thanks! Lots of shiny bits over there... Weeeee! Happily dinging the Amex card!

Running light circuit has a large enough fuse.......been running mine for over a year with no problems.

I did have a problem with getting the SWR down until I removed the paint on the bracket where the antenna mounts. Removal of the paint isn't a problem since the bracket is stainless steel. You would think that getting a good ground using the pigtail that comes out of the mounting would make sure the SWR was low, but it didn't. Point is, you need to check the SWR after the unit is installed.

I hope you'll be as happy as I have been with the J&M unit??? Works well and is easy to make adjustments with one hand, one finger in most cases.....good goods!

Completed CB install Saturday. Tied into switched circuit of left running light. Advisor and mentor on install John L. Wilson said that J&M's recommendations to locate contact point and filter in rear of bike is mainly to keep filter away from engine heat. The complete wiring harness is nestled just under the glove box.

Antenna install went well as the bolt in rear cowling provided a good ground and the whole system tested out with better reception than on John's ST1300. He says due to the ST having an aluminum engine. Installed 3' Firestik antenna for 20 bucks from firestik.com

Have tested out the system Sunday on run to Arivaca with my iPod running through the system.

Sounds were definitely 'Hi-Fi"; however, the wind noise factor with stock windshield and no ear plugs became unacceptable, as the listening enjoyment was ruined by the excessive wind noise.

Running the stock WC down is the only way I can run, as any other up position creates to much wind turbulence. I'm 6'1" so I really need to scrunch down to get in a qiuet pocket. Guess I'll need to look into an aftermarket windshield before the September trip to WESTOC in San Louis Obispo.

Epoche,

Did you get the expensive headset? I bought the high quality headset and with earplugs the sound is fantastic (I wear plugs if I'm on the bike over an hour - so I always wear plugs). My ique-mp3/pda/gps plugs into the J&M and I put the volume no higher than half way at 100+ with earplugs (of course thats air speed - my wheels never go past the speed limit)

The J&M does a lot of amplifying because I can hardly hear my ique when I plug it straight into headphones or speakers.

The three foot mast was sold out so I have a four foot mast....very easy to find my bike!

Mr.Bill,

Yes I have the "high end" head set:

HS-ECD477-FF

My academic history (experimental psychology) includes research into binaural sound perception and listening protocols for evaluating hi-end audio gear. My first impressions of the sound quality if the J&M helmet speakers was that the sound quality was very good; however, the wind noise factor greatly degraded the whole range of listening enjoyment --without ear plugs and with stock windshield.

On my way home on I-19 I put in ear plugs and found that the high end of the sound spectrum was almost completely absent, as was the low end. Am looking at two solutions: (1) a CB 3x5 clear flip, and (2) a different set of ear plugs. My Walmart roll ups are not up to filtering out wind noise and still allowing musical appreciation.

By the by, on first use of my iPod under plastic top to tank bag discovered that the unit gets VERY hot ( here in AZ) and the iPod screen becomes almost unreadable. Guess I'll have to make up a Playlist for the occassion and leave a random run with the iPod down inside my tankbag.

 

[Mr Bill]

Epoche,

I'm not big into audio so my idea of fantastic sound is that I can hear it and make it loud.

I have the cb +2+2 flip, but I don't remember any sound difference with that. The air does go over my helmet now.

I use a stem stand for my Ique - it mounts the Ique just above the J&M unit. Here in New England it's the moisture - hot humid changing to cool nites makes for wet electrics. I much prefer the dry heat where you are for riding.

 

[epoche]

Mr. Bill,

Have ordered a Cee Bailey 4x3 flip for trip to Westoc in September. Feel confident I can get into a quiet pocket at some point in the shield raising cycle.

Yes I do also prefer dry clines; reason we're living here and no longer in Bellingham, Wa.; where we lived for 30 years. The current monsoons, however, make for wet days in the desert for about a month.

Mr Bill

Regarding the CB 4X3 flip. I find that I can run with the helmet shield in full up position and still see the road above the flip. Only noise now comes from the road/motor; although I still use ear plugs on long distance rides.
