 |

Bill,
The second flight in my 601HDS was interrupted by a failed solid state
primary ignition pickup at the flywheel. The other regular distributor
ignition worked
fine. I found the ignition pickup at the flywheel had quit and Mykal
replaced it for free. Haven't had problems since. His contention was that
the part was soldered with
too much heat and caused the problem. Sounds like your ignition might be a
thermal problem found at that part. If you are using Nippon Denso
ignition and both are timed thru the distributor, you might check out play
in the distributor shaft. I'd recommend you look at using NAPA TP45 modules
and IC107 coils.
The TP45 is bullet proof. IC107 coils are different from the cylindrical
type, but they are very dependable. Messenger recommends Standard LX600 for
distributor pickups
as they allow a lower cranking rpm for firing. If you need advance springs
in the distributor, the P/N is #49172 9002. I try to keep a spare set of
parts for the ignition system so they
might be swapped out when something goes amiss.
Haynes Automotive Repair Manual for the Subaru 1600 & 1800 1980 thru 1994
#89003 (681) has a very comprehensive guide and illustrative of the
multitude of distributors
Used on the Subaru and describes rather well the process for checking out
ignition problems.
Hope this is helpful.

Bill,
It is almost certain that your ignitor module inside the distributor has died. These things are notoriously feeble. The worse thing is replacements are about $300!!
Ok that was the bad news. The good news is you can rework this to hookup a TP45 module like Larry Mentioned.
What you do is open up the distributor. Inside you will find a pick up module ( the part that sits next to the shaft)..This is wire to the ignitor module on the outside of the distributor.
You cut the two wires leading from the pick up module to the ignitor..throw the ignitor away.
Extend the two wires from the pickup by soldering a flying lead that will be long enough to reach the firwall. This is where you will mount the TP45 ignitor..I believe it's a GM part..Napa has them.
You thin wire up everything as shown on this drawing I will attach..Hopefully it will come thru.
You can even mount to pickups in the distributor and run two TP45 modules..This is what this drawing shows..But of course that is more work, but if the Stratus second ignition dies, that is the way to go.
Good luck, once you have gone thru this pain you will have a bulletproof ignition. Note I found that at first the system would not work. Then I swapped the pickup to the TP45 connections and everything fired up. Airplane has been running with this setup for several years.
