Elec Distributor and Coil Q's

[bonkas]

What is the go with Hall Effect or Magnetic Pickup distributors? It seems you cant run the high output transistor type coils (~0.5ohm primary Bosch HEC715/716 or MEC717/718 for example) but should run the medium output type type (Bosch MEC723 ~1.1ohm primary) as you will burn out the switching module.

Reason I ask is I have put a GT40 coil on my electronic dizzy but getting intermittent spark - Have managed to get it started twice and flattenned the battery trying, Installing the old coil restores spark.

Do I need a MEC transistor type coil as replacement? I am trying to get rid of engine hunting at idle/low RPM - Tuner thinks it might be coil as I have a weak spark.

 

This is on a 4g63 with dizzy from a L200

Is your gt40 coil a non ballast one being used with a ballast resistor circuit?

It's a non-ballast coil, there is also no ballast resistor in my setup.
