Bill,

First, there is no need for 18ga wire in providing the power. 20Ga
is plenty. So just skip that. Be aware that Klaus does not
recommend anyone ever cut the connector off and reconnect it
their self. Other than not wanting someone to screw up such
a critical part of their ignition system, I don't know what his
motivation is. But be aware that he may not be as interested to
help once someone cuts that off.

Anyway, there's no reason to go 18ga, so just skip that and then
things get easier, and you can run 2 long 20Ga wires to the power
source, or join them into something thicker with your choice in
splice if you wish, further away from the connector.

Hi All,

I am rewiring my airplane and am therefore making wire runs to the
Lightspeed Plasma III ignition systems.

The Plasma ignition systems input connector uses DSub 15 plugs so I have
utilized the M39029/63-368 crimp on connectors for all of the 20-24 AWG
wires that push into the connector however I have according to the
directions used an 18 AWG positive wire and an 18 AWG negative wire for
the power and ground. To make this phase of the project more dramatic,
the Plasma input connector has two positive pins and two negative pins
on its connector so I need to figure out to go from my single 18 AWG
positive wire and divide it up into two wires that will each fit into
its respective M39029/63-368 ORANGE-BLUE-GRAY crimp on connector.

Is there a M39029/63-3XX crimp on connector that is designed for 18 to
20 AWG wire?

If not, I could cut off a couple of strands of the 18 AWG wire to get it
to fit into the 20 AWG connector barrel however that is not very elegant
because the remaining strand(s) will kinda poke out of the wire
insulation however a needle nose pliers could fix that.

Then the next obstacle to Plasma Bliss is dealing with dividing out the
single wire and making it two wires.

I am considering peeling off a 1 inch section of the insulation of the
single wire about 3 inches away from the wire end and then once that
section of wire is exposed, place a second wire with the insulation
stripped off the end onto the exposed conductor and solder the second
wire to the first and then cover the junction with heat shrink.

To expose the first wire 3 inches up from the end could be possible to
do by using my wire stripper to make the two cuts by just squeezing the
handle only about � of the way to have it cut all the way around the
insulation and move the insulation about 1/16 of an inch and then exacto
off the remaining center section.

My soldering skills have much to be desired however if I use a �second
hands� type contraption to hold the two wires together and then use a
clean soldering iron tip and some flux I could do a respectable job.

I would think that�IF�there was an easier way someone here would have
found/invented it by now.

Also, in the past someone told me that a crimp on butt end connector
creates a more secure and durable wire splice than if the two ends were
soldered together. Is that true? Perhaps with my soldering skills that
would certainly be the case however for people with decent soldering
skills I am interested in the actual answer.

Any feedback on this idea/proper suggestions/well wishes would be most
appreciated!!!

..

THANKS!!!

Bill Hunter
