WeirdWeirdHello everyone. Can't seem to find this query anywhere. Been trying to get my recently purchased Dream running. After setting the gap in the points, new plugs etc., no start. Strong spark on the left cylinder and weak or no spark on right side. I remember reading about somebody having to scrape the paint between the coil and the frame after a repaint to restore ground (this bike was repainted). Did that and nothing. We attached a light tester to the spark plug cable without the endcap to see if we were getting power through the cable and when I went to turn it over, guess what?...yep, started right up and scared the snot out of both my brother and I (the throttle cable is stuck open). We were only expecting the tester to light up or not. Question...Does anybody know what's going on here? It seems like a grounding issue but...(I think the boot is not conducting so I have attempted to clean it. If someone thinks there is another culprit I'd be happy to listen. Regards, Jeff H.
"Without the end cap," but using the tester as a jumper, it fired right up. Huh...with the end cap, weak spark. You may have answered your own question. Possibly frayed wiring at the termination point of the plug wire is causing the weak spark, or peer into the end cap itself, check for cracks in the plastic shell. Does the interior of the shell look clean?
Mike Hi Mike. I cut a quarter inch off the wire before any of this and my cap is metal. I took it apart as best I could without bending back the little metal folds and cleaned it up. The bike started on one cylinder with only the left side spark plug hooked up and the business end of the test light stuck in the right plug wire (and completely uninvolved with the spark plug) thus grounded through the test light. I'll give it a try with the kick-start as my battery hasn't come in yet. Jeff
no spark on left sideHey Pop,
Hopefully Jeff got his dream running and he's put some miles on it. Haven't heard back from him...at least on this thread. uh oh...hope thats a good thing!
I am not sure about this, but it is an idea....
Have a look at the end cap, if it has a number and the "ohms" symbol on it you may have the wrong cap. New ignition systems use what is called a resistor cap. There is built in resistance in the cap. Not what you want on an old machine. Older machines occasionally do not like these caps but some seem fine with them..... Try swapping the caps from left to right even if the symbol is not there as they can wear off. Cheers, Greg
