I have a BK2000 and need to replace a 9 pin connector and pins on the
lamp
board? It actually has 8 pins as 1 in blocked out in the middle. Where
can
I get the same part that it came with or do I have to use an after
market
replacement? Hope this made since. I have found some replacements but
they
don't look the same. I am sure they will work but I was hoping to
replace
with factory parts. The reason I am replacing it is 1/2 of the
connector
were burnt to a crisp and melted. So bad that 2 pins came unsoldered.
All
the light where working but I could make some lights flicker on and off
it
I
wiggled it. Any chance there is a problem somewhere that will need to
be
fixed so this doesn't happen again?
Thanks Phil
Ah, toasty connectors. This is due to buildup of resistance between
contact
and pin on board or between wire and contact. As resistance builds up -
heat builds up... which typically causes more resistance... which in turn
causes more heat... until you have your final result - burnt connectors.
Info on connectors here:http://marvin3m.com/connect/index.htm
The originals were IDT (insulation displacement) type connectors.
Williams
and others used IDT type connectors because they are fast to assembly (=
less labor costs)... but these are more prone to failure due to people
tugging on the wires instead of the plug. A better option, in my opinion,
is to replace them with discrete crimp contacts such as Molex Trifurcon
08-52-0113 type contacts and standard 0.156 plug housing.
There are others on this group that prefer to use IDT plugs... to each
his
own. Just remeber - if going with IDT type plugs, you must match the wire
size to have a proper connection. The Pancon high current plugs have the
advantage of using a high temperature plastic which hold up better.
Problem
is - finding these plugs is tough!
Using discrete crimp contacts, on the other hand, have a slightly wider
range of acceptable wire size. For example -- an IDT plug will only work
reliably with 18AWG... but crimp contacts such as 08-52-0113 will work
with
wire sizes ranging from 18 to 20AWG. Downside of crimp contacts is that
you
need a crmper such as W-HT-1919 or 1028-CT.
If buying from GPE -- you would want:
1 x CS156-09-LR plug housing
10 x 08-52-0113 crimp contacts (couple spares)
1 x 15-04-0219 keying plug
Might also need to replace the board mounted header if toasty. For this -
use Molex 26-48-1245 or 26-48-1241.
Don't go with the low cost headers such as CH156-09A-SFL-T. These have a
lower current rating than the 26-48-1245 or 26-48-1241. The CH156 type
headers are good for low power signal connections but I don't recommend
them
for high current power connections.
You can find such connectors

Z-plating.com has them...originals for cheap...I just bought a ton!!!
Yes, they do have IDT plugs. But these are standard IDT's, they don't have
the high temperature Pancons as mentioned above.
