Restoring an old RD400 right now and currently about to embark on this process. The wiring is totally scrambled and isn't anywhere near the original harness, so we're starting it from the ground up on the electrical. Thanks for making this video!
I got brand new main harness and both handlebar electronic assys horn lights turn signals and so on so harness is new harnesses going to handlebar assebblies are all brand new and its a serious pain you cant just plug in colors that seem to match i been plugging them in per wiring schematic and i yet to get anywhere with this last night i got frustrated and unplugged everything inside headlamp bowl im going to start back up again plugging wires in per diagram only difference the headlamp bowl can stay on the work bench until im satisfied its all working and connections are in correct places then i will put the bowl back on i can get harness inside the bowl and while its all plugged in but what a nitemare i need my bike finished summers here
Slow and steady on these electrical projects. I’d highly recommend using a multimeter to test each trace as a check. I like to label each connection before I start installing. It’s a bit of pre work, but it makes the installation less of a pain. Hopefully you have smooth sailing from here!
I tried connecting all the black to black dark blue to dark blue but it don’t work that way I was going to connect each wire per wiring diagram but even that’s proven difficult especially when main fuse is blowing so handlebar switches and harnesses are brand new just like main harness. Brand new one of these times I had negative wire to battery do melt down why ? I have no clue I’m a technician for GM so I’m not new to electrical but this bike is kicking my butt as summer time weathers passing me by. Any ideas would be greatly appreciated. Tonight I’ll start fresh with diagram one wire at a time there all new except warning bulbs and ignition main switch only wiring that’s not new thank you
@@TerenceLeaf1 Take your time and verify each trace. Also your negative lead can get hot if you don’t have a clean ground. You can check resistance with a multimeter from the battery terminal die to the engine case. You should read zero resistance. It’s not uncommon to have corrosion or something interfering with a good ground.

Thanks for watching and writing! Keep us posted on the progress. I get all my connectors from www.vintageconnections.com/Products/Wire
Out of curiosity, how many hours did it take you to do this?
@@edwarddrew5127 4 hours to run all the testing and 12 hours to install / test and sort out all function of electrical system
