Hey guys,
I'm building an xs400 for my girlfriend. I started with an 81 that was basically given to me. It has a good engine and associated gear but the frame and pretty bits are in pretty beat shape. So I got a hold of a '79 that is in excellent shape save the locked up motor. The problem with this bike is it was partially disassembled and came with a couple bags of parts. all unlabeled. And I'm not particularly a connoisseur of these old Yams. Also something that is causing me more grief than it should is the '79 wiring diagram that i downloaded off this site is in German. And I'm not German.
I've the good motor into the good frame and I'm working on getting the ignition all lined up and sorted so I can tune the carbs and get her running right.
This brings up a few questions that hopefully can be answered here.
First, I believe this is the interrupter? Correct? And even though both wires breaking out of the connector are black it plugs into the 2-pin connector with the grey and orange wires near the left coil?
Second, on the motor that came out of the '79 frame I have a 2-wire connection with bullet connectors here:
and on the motor from the '81 frame I have a 3-pin harness connection and the wire colors don't come close to matching:
The the '79 frame that I am using it appears that the harness side of this connection is 2 wires from each single wire connection on the engine side. Can anyone tell me what the difference is between these 2 MY's and where I am needing to make my connections?
Thanks for any help.
