Complete Circuit?
« on: May 07, 2011, 05:06:28 PM »
Hey guys

I've search around but haven't found an answer.  This may sound a bit broad, but do I have to have everything wired up to "complete" the circuit and have the bike run? I have removed the 4 warning lights on the triple tree and am wondering if this will affect the bike's circuit.  Do I have to trace the wires back and remove them, or can I just stuff them into the headlight and call it a day.

My bike has not run since I've owned it and I'm just trying to figure this wiring stuff out.  I want to make sure that I'm not contributing to the problem. The bike is a 72 cb350F if that makes a difference. Sorry if this has been answered, I did search around.

Someone else will probably chime in with a more definitive answer, but when I got my bike, the oil indicator was crudely chopped off by the pump, and the flashers were not plugged in at the bucket.  The bike ran (not quite) fine - but the issues I had were not due to the wires being unplugged.

Good luck.

Troubleshooting wiring issues by removing things may not be your best approach.  I'd start by getting a wiring diagram and make it right.  If the wiring is correct, then check the switches.  When they check out, the last thing to check are the individual components(coils, points...).  Once everything works, then remove what you don't want.

Sorry, I thought you were just looking to see if you could fire it up without those things plugged in.

  333 is right, the wiring, like most things on these bikes, is best put back to stock (or close) before messing with it.  If only to level the playing field and to know where you're at, so you can trace and follow issue that may arise from mods.

No, you do not have to have everything wired up for the bike to run properly.  I just took a look at a CB350F wiring diagram, and it appears that these 4 "warning lights" are all on their own circuits independent of anything that would affect the runability of the engine.

As far as how to terminate the wires... I would personally pull the headlight off and disconnect each one at their respective bullet connectors.  Clipping wires and shoving them into holes isn't really my style  ;).

And on another note.  Are you really really sure you want to remove the oil pressure warning light on a bike that's nearly 40 years old?  I've saved at least one engine from destruction thanks to that little red light.

EDIT:  Nortstudio just replied while I was typing.  I also seemed to miss that last caveat in the OP  ::).  I would agree with Nort and 333 that if your bike is not running due to electrical issues, it would be prudent to attempt to return everything the way should be before gutting thing out.
