Anybody have any technical data for the Slick mags included with 540 supplied by Vans?  I am installing a Slick Start and the lack of data on the mags is a PITA.    

TIA

<?xml:namespace prefix="v" /><?xml:namespace prefix="o" /><![endif]-->  Hi Ron,

  

  

I’ve been working  this subject, also, and have gathered and crunched data 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 SL2-96 that comes with the SlickStart mostly addresses  replacement of existing ignition vibrators, not a fresh new installation. One of  the concerns 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 fire at  twenty some degrees before top dead center (TDC) and create a kick back.  Apparently, the grounding out can be accomplished either by the way the starting  switch wiring is connected or by the way the SkickStart is connected to  accomplish the needed grounding.   

  

Lets set the stage:  I am using the keyed start switch, IO-540D4A5, SlickStart (SS1001), electrical  and FWF kits, all from Van’s. The IO-540 came with a retard breaker Slick mag on  the left and 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. 

  

Per SL2-96,  SlickStart Pin VIN is the electrical 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 are feeding electricity to the starter you are also feeding the  SlickStart. SlickStart Pin GND is connected to the grounding screw on the left  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 retard breaker  terminal. According to OC Baker, the function of Pin 3  is to tell Pin 1 to fire only when the  retard breaker points are open which will be near top dead center. This provides  the retarded spark which is desired while the engine is cranking. So far, so  good.  

  

Now is where SL2-96  and Page OP37-13 of Van’s RV-10 Wiring Harness Manual become a little unclear.  One of the configurations in SL2-96 says 

SlickStart Pin 2  gets connected to the P-lead of the right mag (non-retard breaker magneto). OC  Baker 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) spark while the  engine is cranking. The diagram on Van’s Page OP37-13 implies there should be a  jumper between the R terminal and GND terminal 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” position This seems to be redundant with SlickStart  Pin 2 but it also seems that doing both would not be harmful. I need some help  here 

  

Well, that is what I  have so far. I kick this out to the List for helpful  review/critique/inputs/help/feedback. Please, no flames!

Ron-

  You have done your homework. This is exactly the setup I am using with both the Slickstart and the switch grounding the right mag. Only reason for the double grounding is a backfire can be very expensive and the cost is zero to add protection for a broken wire.

Additional info re SlickStart:

   

  I had noticed a lot of ringing on the Left magneto P-Lead and am blaming this on the SlickStart. My engine monitor picks up RPM from the P-Lead. When connected to the Left mag, once in a while I got strange RPM values. This was immediately fixed when I moved the pickup to the right mag.

   

  This is not a reason to be cautious of the SlickStart as I believe the SlickStart and breaker retard mag is a great combination at a good price.

Thanks Roger, this is  excellent input!

  

 I have a Push button  start and have wired the start circuitry such that the start button will only  energise the starter/Slick start when the Right Mag is grounded.  I also  have a retard breaker on the left mag only.  No impulse couplers on either  mag.  Funny, I thought an impulse coupler on the left mag was  standard.

  

 Seems my install will be  quite straightforward.

  

 thanks again

 Ron

<?xml:namespace prefix="v" /><?xml:namespace prefix="o" /><![endif]-->  Yes, Ron, I expected an impulse coupler on the left mag, too. When I  discovered no impulse coupler, I ordered the SlickStart. I still don't know if  having redundant right mag grounds is OK. I am leaning toward just using the  jumper on the ignition switch and leaving SlickStart Pin 2 disconnected. Maybe  someone else will chime in here and set us straight.

I have the same setup in N939SB and ran the grounding wire from the SlickStart to the right Mag P-lead and also grounded the right Mag P-lead during start switch activation. Since a backfire could be very expensive and the cost of running both wires is zero, I believed this was cheap insurance against a broken wire. No issues at 160 hours.

Joe-

  I can't think of a design reason to drop pin 2 functionality except to limit their liability in lawsuits. I suppose that every kick-back lawsuit will automatically name Unison as a defendant and they can create uncertainity by blaming the right mag.

   

  I looked for information on the new version with no joy.

   

  Does anyone have a description of the changes between new/old?

  Is the new version now being shipped?

  Can anyone send a new wiring diagram?

   

  Thanks,

  Bill
