Guys I am now stuck. I have the NL starter and also wired the plane as per 

Vans wiring kit which I now know is wrong for this starter. I contacted Vans 

and they are not interested in helping as not the starter they supply.



Can somone have a look at the skytec diagram and give me an idea what wires 

to change. Ofcourse if you have not used Vans diagram you will not know the 

difference.



Vans starter relay has 4 terminals and Skytec diagram has 3. Also Skytec has 

1 wire going to the starter not 2.

I tend to think you have the wrong  relay. The starter relay is normally 

an intermittentduty model, with 3 terminals as shown in the Skytec 

diagram. Master relays normally have 4 terminals. I note that the 

pictures in the Spruce catalog are also reversed.

In my experience the master has 3 contacts and the starter has 4.  Ground

closes the master and power closes the starter.

I too have the 149-NL starter (that came with my TMX-540) and it is 

wired per Van's Lightweight Starter Circuit with the "I" terminal 

connected to the smaller stud (jumper removed).  It's working just fine...

Thanks Brian if it was not for this list I would had a stuffed starter. 

Enjoy your flying.

I am not sure if I can add help or more confusion here. But I wrote this question to SkyTec since I wanted to know what to do with my 149 NL Starter which came with my the TMX IO-540.



Quote:

Michael,



Per that page, "All Sky-Tec NL starters must be wired per diagram "B" below as there is no active "S" terminal.  The small, "S" terminal on the NL model starter is used to switch the starter from 24V (jumper wire removed) to 12V (jumper wire installed) operation and cannot be used to activate the starter."



So yes, assuming you are running this thing on 12V, you will need to install the jumper.



It is confusing.

I read here to keep the jumper on!



Do I miss

something?

The diagram he is referring to is here: http://www.skytecair.com/images/NL%2012V%20Installation%20Wiring_1100.jpg



Also attached.  My TMX-IO540 also came with the NL starter and I wired it per this diagram.

Sky-Tec repurposed the S-Terminal functionality on NL model starters to 

serve as a means of switching the starter between 12V and 24V operation. 

Because of this, ALL NL STARTER INSTALLATIONS MUST BE WIRED ACCORDING TO THE 

CERTIFIED AIRCRAFT WIRING DIAGRAM BELOW - NO EXCEPTIONS!

http://www.skytecair.com/images/NL%2012V%20Installation%20Wiring_1100.jpg

I noticed on the starter when I put the jumper back it says someting like 

jumper for 12 volt operation. So if that jumper is used it becomes a 24 volt 

starter. I must have had a coeliac moment when I first removed it.

I think you have it backwards.  When the junper is ON, it's a 12 volt starter;  when the jumper is OFF it is a 24 volt starter.

This is interesting.  My starter relay has FOUR terminals and came with a tag that said "If original has 3 terminals DO NOT use this "I" terminal."

Think you got the wrong guy attached to the quote below William.  That was Brian Sutherland that said that, not me.

And I should have probably added the statement:  Prior to flying Sunday 

I'll be pulling the cowl and disconnecting the "I" lead and 

re-installing the jumper.  The reason I haven't had a problem is that 

12V is still being supplied to the 12/24V stud via the "I" lead rather 

than the jumper.  I may be wrong but my guess is that Van's diagram for 

the LS provided a safeguard against a stuck starter relay in that the 

starter also must see 12V via the S/I leads coming from the starter 

switch.  Obviously this is problem for the NL as a stuck relay would put 

the starter in 24V mode and likely result in damage.
