Hi

I have three Swedish T44 diesels, 37945, new orange GreenCargo, 37943, old green GreenCargo and 37942 MTAS. The new one I haven't run much yet. The old ones have a problem. The slightest glich in power and the sound hang, I can stop the engine and the sound is still full speed. I have to press STOP and start again. Someone then said that the old mSD used in 37943 and 37942 is junk. The new mSD3 used in the new 37945 works much better. So I got a 60976 mSD3 decoder and a 60971 programmer and programmed it as a 37945. I just want to pull out the old mSD and insert the new mSD3 instead in the old green GC and MTAS. I don't want switch board. Then I figured why not test adding a 60974 too when I'm at it. Of course the board that comes with 60976 has a SUSI connector for the buffercapacitor 60974. The board in the engines doesn't. And the manual for the 60974 says nothing about how to connect it to the 21-pin connector when the SUSI-connector is missing. Anyone know how to connect it? The photo shows 37945 and 37943 untouched.

I found one photo on the net that suggest that top pin on the SUSI connector goes to orange, pin 2 and 3 goes to pin 5 and 6 on the 21-pin connector. The bottom one I don't know. Maybe the connection is on the back goes of to somewhere that I can't see really. 16 possibly.

I also found in this forum that 16 is orange. Maybe the the bottom pin is ground then, pin 20.
