Trouble shooting Drive Impulse control

Hi All,

My R20-16 (1993) stopped driving this week and I'm trying to find what's wrong. I've got the service manual to help me through the troubleshooting but I could use some extra info.

Does anyone know how the pins on the circuit board connector from the Drive Impuls board are numbered? The picture in the servica manual is confusing me :)

I don't have the service part 'Firing circuit - part 147803'' I think this is to trigger the thyristors. Can I replace this part/function with something else to complete the troubleshooting?

Tank you for the advice.

Best
