testing digital outputs

[miniminor63]

Hi

I am currently testing the outputs on my board. I have ignition drivers on EC10, EC24, EC34 and EC36.

To start the two first ones I write mdhE2 and mdhF2. This works fine. But to test the two others I write mdhA2 and mdhB2. those does not give me any voltage on EC34 and EC36.... Are the IGBT's fried? They are more  neatly soldered than the others, and I cant see anything obviously wrong. Are the mdh code wrong?

Also, how do I test the injector outputs? I dont think its very intuitive how to turn them on and off?

Cheers

You can't test channel whic are in output ignition table.

[miniminor63]

yes, just figured that out!All the ignition outputs work!

Also I would like to test the injector outputs, but dont really understand how to turn them on and off?

Just put in output table ignition igbt that you don't user. If you use igntion 0,1,2,3 , than in output table(igniton) put 00 and 7 (ec36 pin 10) for test.
For injectors test you don't need to do that.

I have seen that one, but cant really seem to get my head around how to start and stop the injector drivers... May be a bit thick

how is your h table?

To turn first injektor is mdh90 turn off mdh10
For second mdha0 off mdh20
third mdh80 off mdh00
fourth mdhb0 off mdh30
To see if injectors outputs works you must connect somting(i test with 1-10kohm)

[miniminor63]

ah, right, so I can not test it with a DVM? Thanks for the info though!

[rob@vems.co.uk]

If h[0] was changed from:
h[0]=04 01 02 08 00 00 00 00
to:
h[0]=04 01 02 08 10 20 40 80

Then you'd be able to use INJFET 4, 5, 6 and 7 to drive high current devices.

[MWfire]

You can test with dvm, but when is nothing connect allways is 0V.
When you connect resistor(from 12V to injector output) and injector is off then you read 12V.
When you turn on injektor you read 0V.

[miniminor63]

yes I understand. Thanks!

Rob, yes I know. but all I am going to use it for is 4 Cops, 4 injectors, water pump, fan, fuel pump and tacho. The pumps and fans is of P259, the tacho with a pullup from P259, and the rest has their own FETs/IGBTs.

What more should I need?

[MWfire]

idle motor?

[miniminor63]

on ITB's and does not have one Racecar pretty much, so not really needed either.

Well I've always found that if I come in halfway through the conversation I get the wrong end of the stick.
