All-

     My Icom A200 has a main  connector with dozens of Molex connectors that have to be crimped. I think the  crimps can be done with those provided in a standard wire stripper, then  soldered. True/False?

Bill, 

 Yes, Molex pins can be crimped by hand and then soldered, however there is  a special tool for the purpose that "folds" the ears down first on the wire and  then a second crimp to secure the wire. When using the tool no soldering is  necessary. It is preferable from a fatigue standpoint to install the pins  without soldering.

Hi Bill,



 It is considered better to crimp the connectors with the appropriate tool rather than soldering them.  While solder will, indeed, hold the wires in place there are issues with vibration and wire breakage.



 My advice to you is to spring for the crimper and do it right.  You can locate the appropriate crimper at most electronics distributors or by looking at the Molex web site.

Hey Bill,

  

 Don't know what you mean by "standard wire stripper" but don't use the type of wire crimper you find at the local auto parts store.  also, don't solder and crimp.  Get a good set of crimpers from someplace that knows aviation systems such at B & C Specialty.  Here's their website. http://www.bandcspecialty.com/  It'll make the job much easier and give you tremendous peace of mind.

Someone has already sent you to B&C for the tool.

Bill,

I had problems with soldered connectors in my A200 and after a 

protracted effort, a repairman had to crimp the pieces to get the good 

contact that was needed.



*June 6* After a search of the Matronics page, the Aero Electric 

connection, a comment on poor contact between the edge connector and 

pins used on the ICOM A200 was found. I went to the airport and wiggled 

each individual wire and found the M and 11 power input wires adjacent 

to each other would cause erratic variation in volume. The radio was 

removed and then the two pins were carefully removed. The tabs were 

spread and the pins were carefully reinserted. Then the volume had to be 

lowered on traffic reporting at a 100 miles out even with the hanger 

door still down. Wiggling the wires still cause the signal to vary 

considerably, but the problem is identified and now only requires a 

solution. Molex edge card connector p/n 09-50-6155 and pins p/n 

08-03-0303 will be ordered from Mouser Electronics tomorrow by phone. 

Thanks again to the Matronics subscribers.



*June 7* Pins and connector were ordered from Mouser and my insurance 

was bound with AIG shortly after. A 3-piece set of 6-ft static-ground 

wires with gator ends was made to allow refueling on a regular gas 

basis. The Illinois Department of Aeronautics Registry was called and 

forms were requested to get the airplane sticker needed to show 

compliance with the state user tax. Out at the hangar, the radio was 

again pulled and pins were adjusted outward with better results, but 30 

new pins and connector pre-wired and glued in place may be in order. 

There's just too much play in pin position with the radio in to fly 

without fixing this. Tomorrow, Tim will take a look and hopefully adjust 

the side tone and possibly offer suggestions.



*June 8* On this semi-rainy morning the aircraft was open and accessible 

at 9:00 a.m. Tim arrived and after checking out the contacts, wires and 

intercom, he soon resolved that the radio problems are with my 

connector, some incorrect shielding and the manner in which I soldered 

the pins. He removed two screws holding the connector using a foot long 

screwdriver and pushed it out from the inside to gain more direct access 

to pins while remaining connected. He determined another less abused 

connector was needed. I closed the hangar, had lunch with the guys at 

the Lucky 8 and visited Warren electric without success. Then I called 

ICOM parts and was able to order one in stock from them. Now we wait for 

one in the mail from ICOM and one backordered from Mouser Electronics to 

see which gets here first. Thirty pins are already on their way from Mouser.



*June 9* It rained on and off today. The ground wires that FAA inspector 

wanted tie-tied off were finally secured. A standard oil filler neck 

from my spare EA-81 was compared to the customized Stratus design. One 

could conclude that the filler should be turned toward the other side 

proximate to the dipstick so that the access door would suffice for both 

checking and adding oil. It doesn't seem it would be a lot of work to 

remake the tube to get it there. Tim was unable to get the external snap 

ring off the 90-degree coax fitting inside the radio case, so I made a 

tool for reaching it like Tim's so it might be out before we resume.



*June 14* With thunder and rain this morning, the hangar door was opened 

and there was enough light to remove the new oil filler tube and 

reassemble it with a proper amount of gasket sealer. The short 40-degree 

off angle 6mm Allen wrench was cut to 5/8" and the other end was bent as 

well as twisted by the width of one flat. This made it possible to 

tighten the nearly inaccessible bolt in short increments alternating 

ends. Tim arrived after noon and began cutting wires from the old 

connector and putting proper crimps to new pins and snapping each in 

place one by one into the new connector. I was humbled as I watched him 

crimp the pins so perfectly. I had incorrectly assumed they could be 

crimped and soldered, but they just don't fit well in the connector as a 

soldered pin. Within an hour or more, the radio was slid in and a radio 

check to ground control was very clear both ways in both headsets. Later 

in the evening, Lee and I visited the hangar to add a little insulating 

tape and some tie-ties to secure things again and the radio work was 

finally done.



What a hassle!  Recommend you crimp the pieces, not solder. Also, do 

this prior to installation of the connector and support tray.

Larry-

    Three questions-

    1. What crimper finally worked?

    2. "Prior to installation of the connector and support tray". I was 

planning on "Nailing down" the tray after the BNC antenna connection had 

been installed. How does the pre-installation of the Molex connector to the 

tray have an effect?

    3. I thought you had a Becker com.

    Attached is a picture my brother and I found over Christmas of my dad at 

the end of WWII. What is the twin behind him? NO FAIR LOOKING IT UP!!

Bill,

The crimper he used was specifically the three stage fold and crimp, but 

it was his crimper and the ability to do the job without soldering that 

made it work.

I found it really awkward to wire the Molex connector in place with the 

tray already installed. We worked around that with close proximity to

the header tank and that just made the job much longer. A wired Molex 

connector and "free tray" would at least offer and easier opportunity to 

examine the

plug and wiring installation prior to a final push-in connection with 

the radio. I have a Becker transponder and an ICom A200. My pathetic 

crimp/solder

work wasn't discovered as a poor connection until all was in place. 

Removal of the connector was an especially difficult complication. Thank 

God I made the forward

top skin removable!



Golly, it looks like cross between a single tailed P-38 and a U-2 

cockpit for camera or light bomber work. Surely a fast plane, but what 

is it?

I don't know.

That's a Grumman F7F Tigercat. The single engine tail dragger on the  

other side is an F6F Hellcat.

Bryan-

    Correct. I forgot I was on-list instead of talking to Larry direct. I 

should have cropped out the Hellcat and it would have been harder to 

identify. Gotta admit, not too many pictures of them around!
