I have a 0.4.4c board which has been working well. 4cyl engine, wasted spark & semi sequential injection , just a crank signal. I started having some intermittent epsiodes where I would lose spark. Stopping the engine and restarting after a minute fixed it, but then it failed completely. I've checked the crank signal on an oscilliscope, it is good, and replaced the vr conditioner, and now have it back on a jimstim - the injectors are firing properly (and the LEDs show this), but the ignition channel LEDs are all lit solid, and there is no output on any of the ignition channels. My conclusion is that the ignition outputs have failed for some reason. Has anyone else seen this? Am I missing something?
- I've confirmed I have a good crank signal, and I am getting rpm & injector ouput from the speeduino. All other inputs/outputs are working.
- I'm using a jimstim on the bench, everything working, except:
-ignition LEDs are lit solid, and there is no signal on the ignition outputs
BTW makes no difference if I set the ignition output for 5v or 12v - no signal either way
