Matthew Oliver Posted March 29, 2011 Report Share Posted March 29, 2011 Hi All Im helping a mate with his 86 RX7 Savanna and Im a bit stumped with the way he has set up his coils, Ive got some theories on whats going on but Im not 100% sure Setup is as follows: -4x Bosch HEC-715 coils and a 3 channel Link Ignitor The Leadings are running off 1 channel each and the trailings are running off a single channel in parallel (pretty much wasted spark setup). The leadings are sparking fine and triggering the timing light as expected. The two trailings we were having problems getting spark with, we would always get a weak spark and it wouldnt trigger the timing light we are using. We changed to some hotter plugs and weve now got spark (we beleive from just listening to it when the hotter plugs are fitted and it runs alot better) but still not enough to trigger the timing light. When we pull the lead away from the plug a bit and let it arc across we get the timing light going. My thoughts on this are to get a coil that has 2 posts and a single winding or run 2x 6 volt coils in series, but trying to source either of these is a bit of a nightmare so we would like to utilize what we currently have. Can someone provide some insight to whats going on here? Quote Link to comment Share on other sites More sharing options...
