Something caught my attention and I need to ask for advice.
I looked at my "Autohelm 6000 Service
Manual" and the TR1 listed for my Z051 Course computer is "NPNBDW398".
However, looking at my pics on posts #20 & #21 the TR1 has the print on it: "SGS 28737 BDW93B".
To me these don't seem like identical parts
or am I wrong?
See pic from the Service
Manual under "7.5 AH 6000 TYPE CR COMPUTER PCB (Z051,Z052, Z062, Z063)" - page 76 part number listing:
Noticed on the Service Manual pcb circuit diagram the TR1 however seems to be labeled as "BDW93B" (the old photocopy quality is poor)
Is this just a case of different part numbering standards?
What's the explanation? Same part different names, or do I have a wrong part on the pcb, or is my service manual incorrect?
When I hunt for the part which part number should I ask for?
