Engine without sparks, again.

The output is not working is 36. I have verified.
Anyway, only 34 emits a spark every time it is given to the starter engine.
   The output 33 and 35, connected to the coils do not generate any spark. Are negative, do not lead.

  I continue to await your news or instructions.
Thank you.

There are a four other ignition pins - two of them have IGBTs on them.

Sparking only once on start seems very strange behaviour.

Good evening!
What of them?, Rob.
You could find out how my unit is initially configured? You remember the Vems 3.3 No 868

rob@vems.co.uk

Yes I am still awaiting a response from VEMS HQ.
You could try testing each of the other four pins to see if you get a solution before they answer.

Hello! Good evening!
I prefer to wait. I do not want to fry anything else.
Thanks.

rob@vems.co.uk

Can you confirm that you've disabled the secondary trigger please?

Thanks

Rob

If it helps,the scheme of connections, you sent by email and came from the following address:

Okay, if you have 34 and 36 the other two channels are:

Pins 11 and 12.

NO, no, no!!!!
Rob, I am sure, this unit only had two exits, the 34 and 36. Remember, I bought it through you.
   In another vein, I opened the box and had a track burned. I made a jumper on the track and then had burned an IGBT.
   Now everything has to be revised.
    You have IGBT?  You can you send me a full game?
    Now I need to urgently repair the unit.

rob@vems.co.uk

When I checked your order I saw that it was a 4+4.

Burning a track means that you've managed to put a lot of current through the unit.

Are you 100% sure that there were no spare IGBTs (the FETs are all black plastic, the IGBTs have a metal tab).

I'm not sure if I have any spares, normally I would direct people to the webshop - if you are in a bug rush you might want to consider using an OEM igniter pack.

chencho16000

In the motherboard there are only two IGBTs with a sheet metal.
The rest are all black.
Can you explain me, please, how I can use an OEM package of Ignition?

rob@vems.co.uk

The standard external igniter packs are IGBTs in a heat sink - so you can use any of the logic or stepper outputs to drive them.  The following shows a connection to an OEM pack

Using the stepper output but you can just as easily try EC36pin33 and 35

chencho16000

I do not understand.
can you give me more details?, please.

chencho16000

Hello!
I have reviewed again the motherboard and actually, sorry, ;) there are two more pinout, the EC36-are 10 and the EC-24.I´ll connect and check if they function properly.
Before that I wanted something: :-\
In reviewing the motherboard, I noticed that the IGBT chip is the one that is connected to pin EC36-6, which in my schedule is the one that controlled the idle valve.
Could have affected other parts?
How can I test? to exclude other incidents.
Thank you.
