Subject: ignition gremlins, still!?


78 auto tranny mostly stock.


.  try to start, get VERY weak spark.
.  jumper from battery to coil +  very strong spark
.  can remove jumper and engine continues to run and can be shut off with key. 
but engine won't restart without jumper.?



obvious leakage (have cold start relay)

gregg potts suggested a relay on coil

so took + wire to coil and ran trigger to coil and hot from battery thru relay 
to coil.

fires right up, but won't stop  turn off ignition and engine keeps running 
somewhere leak keeps coil relay energized,
pull wire from relay engine stops


so obviously there is a current leakage that holds the relay energized that 
allows the engine to keep running.??  where.

so

1.  real fix when it gets warmer, where is problem keeping coil from getting 
full voltage for starting.


2. short term fix (gerry rig) where can I get a solid off/on cuircut to trigger 
the relay controlled by ignition switch???


ideas? suggestions,
easy fix always appreciated.

have been staring at wiring diagram for month and only thing happening is 
eyeballs falling out. ;{

this all started with cold weather (this is in theory a daily driver) so it 
appears the spark was weak but sufficient to get her going until things got 
rough.

new coil
new double relay
all tests in Bentley are nominal,

?????


5 months to find, 5 minutes to fix, I hope not

thanks
Bob
