bonkas Posted October 19, 2020 Share Posted October 19, 2020 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 Quote Link to comment Share on other sites More sharing options...
Valiant Posted October 19, 2020 Share Posted October 19, 2020 Is your gt40 coil a non ballast one being used with a ballast resistor circuit? Quote Link to comment Share on other sites More sharing options...
bonkas Posted October 20, 2020 Author Share Posted October 20, 2020 It's a non-ballast coil, there is also no ballast resistor in my setup. Quote Link to comment Share on other sites More sharing options...
