IGNITION PAGE
I need to figure out what the 4 pins are for on the connector. Disclaimer, the info below is all based on assumption...
- 4 pins - THIS IS HOW WE THINK IT WORKS
- 1 pin for a pair of cylinders
- 1 pin for the other pair of cylinders
- 1 pin for power supply
- 1 pin for ground
- Fire state pins 2-3 are ground. Wait state pins 2-3 are +5v. Don't ask me why I don't understand (yet)
- New Theory:
- Coilpack is triggered on +5v instead of switched ground
- to be determined...
- also possible
- 1 pin for power supply
- 1 pin for ground
- 1 pin to trigger spark
- 1 pin as HV (secondary side) return (easy to test: appr 10..20kOhm with the sparkplug connection, maybe only in one direction)
