912 trigger coils wiring
Hello to all
I got an issue very rare for me but maybe some one can put some light on this odd situation. This what happens to me: I got an issue where I thought that one of the CDI or one of the Ignition coils where bad. When I did the CDI checks, "A" module no problem but when I ran the "B" cdi module, look like the engine wants to jump out of the plane. I start troubleshooting and eliminate both CDI's, and both power plugs for the CDI's, Ignition coils, all work fine; Then I start the testing the trigger coils; I Unplug the 4 pole connector from the lower CDI and ran the top module, and test ok, but when I unplug the 4 pole connector of the top module and tried the lower CDI, there is where I found a hint of where the problem was;
I start checking the triggers coils one by one as follows. First, I check the ohms from wire to wire, Checked one wire to ground and check, then last check was the integrity of the individual wire from the connector to the end at top of the coil, the top trigger coils pass with bright colors but incredible as it show up the problem, at the lower trigger, one trigger pass the test the other failed as this. ohms and integrity of trigger coil pass but (never see this before) The both wires continuity fails to pass; some where inside the shielding and the insulation of that particular trigger wiring, is an opening where the continuity failed. I thought was my meter but was not; I got a second one, re-checked all triggers (Ohms, and the integrity of the wire) but just that trigger coil fails on the integrity of both wires from the connector to the top the coil. Can some one help me out about this issue because I can not understand how this happens.
Any comments will be very appreciated,
Luis
