=0A=0A I have a Push button start and have wired the start circuit
ry such that the start button will only energise the starter/Slick sta
rt when the Right Mag is grounded. I also have a retard breaker on th
e left mag only. No impulse couplers on either mag. Funny, I thought
an impulse coupler on the left mag was standard.=0A=0A Seems m

Re: RV10-List: Slick Mags=0A=0A=0A Hi Ron,=0A=0A
I've been working this subject, also, and have gathered and crunched d
ata from a number of sources to find what we need. The best data came
from OC Baker on the AeroElectric-List. The Slick Service Letter SL2-9
6 that comes with the SlickStart mostly addresses replacement of exist
ing ignition vibrators, not a fresh new installation. One of the conce
rns not clearly addressed in SL2-96 is how to ground out the right mag
out while cranking the engine to ensure that the right mag does not f
ire at twenty some degrees before top dead center (TDC) and create a k
ick back. Apparently, the grounding out can be accomplished either by
the way the starting switch wiring is connected or by the way the Skic
kStart is connected to accomplish the needed grounding. =0A=0A
=0A=0A Lets set the stage: I am using the keyed start swi
tch, IO-540D4A5, SlickStart (SS1001), electrical and FWF kits, all fro
m Van's. The IO-540 came with a retard breaker Slick mag on the left a
nd a non retard breaker Slick mag on the right. The retard terminal is
labeled on the left mag. No impulse coupler is on either mag.=0A
=0A =0A=0A Per SL2-96, SlickStart Pin VIN is the elect
rical supply into the unit and is connected to the output side of the
starter solenoid through a 5 amp fuse to this pin. Then whenever you a
re feeding electricity to the starter you are also feeding the SlickSt
art. SlickStart Pin GND is connected to the grounding screw on the lef
t mag (retard breaker magneto). SlickStart Pin 1 is connected to the
P-lead terminal of the left mag. Pin 3 is connected to the left mag re
tard breaker terminal. According to OC Baker, the function of Pin 3 i
s to tell Pin 1 to fire only when the retard breaker points are open w
hich will be near top dead center. This provides the retarded spark wh
ich is desired while the engine is cranking. So far, so good. =0A
=0A =0A=0A Now is where SL2-96 and Page OP37-13 of Van
's RV-10 Wiring Harness Manual become a little unclear. One of the con
figurations in SL2-96 says=0A=0A SlickStart Pin 2 gets connec
ted to the P-lead of the right mag (non-retard breaker magneto). OC Ba
ker says that the purpose of Pin 2 is to ground out the right magneto
so that it can not fire an advanced (twenty some degrees before TDC) s
park while the engine is cranking. The diagram on Van's Page OP37-13 i
mplies there should be a jumper between the R terminal and GND termina
l of the keyed start switch. And that this jumper causes the right mag
to be grounded only while the keyed start switch is in the "start" po
sition This seems to be redundant with SlickStart Pin 2 but it also se
ems that doing both would not be harmful. I need some help here=0A
=0A =0A=0A Well, that is what I have so far. I kick th
is out to the List for helpful review/critique/inputs/help/feedback. P
lease, no flames!=0A=0A=0A=0A Roger Standley=0A
