I have finally decided to change my secondary ignition module to the TP45 from the Stratus supplied unit. I searched the archives here but did not find any definitive info on the coding of the three wires coming from the Stratus supplied flywheel pick-up.   

   

Here is what I found in the archives:  

   

Coil + goes to TP45 B terminal  

Coil – goes to TP45 C terminal  

Magnetic pick-up + (usually a red wire) goes to TP45 G  

Magnetic pick-up – (usually a white wire) goes to TP45 W  

   

   

The magnetic pick-up I have has three wires, Red, White and Black. The suggestions above from the archives did not work. Can some one using this Stratus supplied pick-up tell me which one is which? I assume the third wire is +12v.  

   

Thanks,

Hi Hugh,

I looked at my ignition this evening and find three wires red black and 

green coming from the pickup to a plug connected with the solid state 

module that goes with the flywheel pickup. From it, two wires red and 

black come from the solid state box to my B coil, red to the black with 

white stripe coil wire and the black going to the blue coil wire. I'm 

not sure that you could use the TP45 in replacement of the solid state 

box provided by Stratus.

Yes this is the first time I have heared of somebobody trying this.



Besides, last time I was standing in Mykal's shop there was a little

pile of flywheel pickups that ther labelled "bad" So I would not be

surprised if using the TP45 is not replacing the unreliable part anyway.

The Twin TP 45 system builds two subaru pickups into the distributor,

each of which drive a TP 45 (same as the GM 4 pin module).



Of course you need a second pickup. I happen to have one if you need it.

Thanks to everyone for the responses so far.



Is the second pick-up people are putting in the distributor the same as the

original (i.e. something I can pick-up at NAPA)? 



Also, is the second pick-up easily installed in place of the original

ignition module, or is there some mechanical work that needs to be done? 



I am some what reluctant to replace the primary ignition since it has been

running fine for years, hence my trying to get the TP-45 working with the

existing flywheel pick-up. However, I am not exactly sure what part of the

secondary ignition is actually causing the problem. If a second pick-up

installs easily in the distributor, then I guess that might be the simplest

path.



Thanks, Hugh

Hugh,

The second pickup can be had as an LX600 from NAPA Auto Parts.  They're 

about $60.00, but very durable.

The addition of a second pickup in the distributor requires removal of 

the Nippondenso module (replacing it with two TP45 NAPA modules) 

locating them on the firewall.  The disk that holds the pickup has to be 

removed from the distributor and drilled and tapped for the second 

pickup or a new disk made for the installation. Both pair of wires are 

lead back to the firewall to the TP45s.  Each has a IC107 coil mounted 

on the firewall and the bolt pattern for the coil can support the TP45s 

as seen in the links below.

If you decide to do the dual ignition pickup within the distributor, let 

me know and I'll send you the information for

the disk size, material, locating the holes and tap data. The disk is 

fussy work but not that hard to do.  If you need a disk

I can turn one for you if you decide this is what you need.

As I said, I have never heard of anyone using the crank pickup to drive

a TP45. The second problem is although your existing ignition is working

fine right now, you only have to have you primamry coil winding

resistance drop a little bit and it will fry the original soob amplifier

chip. They are notoriously feeble and they fail without warning!



The dual pickup is the way to go. You will need a second subaru pickup

(the pickup part does not fail) and pull all the guts out of the

distributor and make a new base plate...If Larry can turn you one up

that will be the simplest way...For half a days work this will be the

most profitable thing you can do to improve reliablilty...



Well that's assuming your valve guides don't fall out of the heads

..But don't get me going...
