yeah I have a make-shift test light with alligator clips and a 194 bulb. when the points are close the light should be on? and when they open at the firing mark the bulb should go off?

lol....no not yet. the points I got to replace the burnt ones were "o.e." style. im not sure they are going to work. so I got a points file and filed all the discoloring and pits from the factory ones, tried to get cylinder one point set and im still off about a centimeter or so with the plate adjustment to have the point opening on the firing mark...im beginning to think that maybe its out of time as far as the chain side. it did run prior to trying to square up on all the electrical work. not super well but it had bad petcocks constantly dumping fuel while it was on or off. the carbs were clean and needed to be rebuilt. which ive since corrected those issues. I have to do some research and figure out how to see or check if the engine timing is off other than the points being off...

Well I scrapped the idea of using the points and got the newtronics kit from yam bits. I have it 99% hooked up. Its statically times and light goes off right at firing mark. However I'm a little stumped with the red/white wire going to the coils. There's a red/white wire lead off the newtronics box that has a jumper at the end. One end has a Male plug in and the other is female. Each coil has one Male and one female from it. Do I plug each red/white lead from the box to one coil? Or Male to one coil and female to the other?  I guess I'm just not understanding the diagram correctly...

You mean you have it statically timed so that each LED goes off at the correct mark for EACH cylinder firing mark?  Remember you effectively have 2 separate ignition systems on these engines, firing at different times 180 crankshaft degrees apart.  This is 90 degrees apart on the camshaft and timing plate- hence the 90 degree offset for each points set and now the Newtronics sensors.  If you understand the theory and how it should work- it is easier to install and troubleshoot- points or Newtronics.

The red/white is the power feed to the Newtronics box only- it can be connected to either coil feed or indeed any ignition live cable.  The Newtronics box then imitates the action of the points by grounding or interrupting the coils return path to frame through either the orange or grey wire (left and right coil return), via its blue lead with tag.

One caveat with the Newtronics which is otherwise an excellent system- even more so you need to take care not to leave the ignition switched on and engine stopped- you will cook the coils.....

Yeah the light on the unit turns off as  each cylinder reaches its firing mark. I'm not by any means an electrically inclined person so I need very basic terminology for it lol. I understand how the plates and sensors work together my only issue right now is just the red and white wire. So that can be hooked up to just one coil? It doesnt need to be hooked to both? Does it matter which coil its connected to?

Its the terminology that can get you drifting away from understanding what is going on  ;)  You are not hooking the red/white up to either coil- you are merely using the same ignition live feed to the coils- they are both fed from this common feed and the ignition circuit only seperates after the coils- the orange and grey circuits.  So yes- you can use the Newtronics male/female sub harnes to splice into either coil feed.

so I figured out what my misunderstanding was...I was caught up on the fact the red and white wire off the switching unit had a male/female jumper lead off the end of it. but that's just power in to the box. so that had to be spliced in with the ignition feed to the rest of the bike....kit is all set up. statically timed. lights on box go off as each cylinder reaches firing marks. now, however, I have spark at each spark plug. but the spark is very weak...now to figure that out....

Apart from the battery voltage, start looking downstream of the newtronics system. Check continuity of HT leads, coils and grounding strap to case. I upgraded coils on mine and it made a small difference to spark but a noticeable difference to running.

Great news. Today it fired up. Run alright. Responsive throttle. I put my old coils and condenser back on. Solid spark. Took a bit of cranking for it to fire up. Thanks a million for all the feed back and patience from everyone with my lack of experience knowledge and terminology. Few loose ends to button up and were ready for the road!

Glad to hear you got it running.

Sorry, but i don't understand; you mount the condenser with the newtronics kit?

No, the condensers (there are actually 2 mounted on the same sub-plate, one for each cylinder) are not used with the Newtronics system.

ah, ok thanks!

do you mean that these are 2 condesers on the same plate?
