Hi,the sons 535 only sparks on front pot. fitted new rear coil ,,same,, swapped coil wires ,,rear pot sparks, non on front,,test light on grey and orange wires at tci, grey makes bulb glow and orange makes it really bright, earthed on cylinder, swapping wires on coils I believe both coils, leads, caps and plugs ok as sparks ok from original coil Read up on T;net and earthed battery to frame. earth cable under tank sorted,put earth on black at block with grey and orange coil wires, had side stand up/down clutch lever cabled to bar,switches on bars operated but still no spark on rear pot. any ideas or shall I break it,,,please..

I have 2002 road star midnight. I lost completely spark on all 4 spark plugs. Before bike was running OK but sometimes on low RPM while idling would skip a firing on a at least one cylinder making spufff like sound. I put new spark plugs, and wiggled a little coil wires. Bike with new spurk plugs would not fire up at all. Checked for spark on all 4 spark plugs - no spark., not even an electrical I lost completely spark on all 4 spark plugs. Before bike was running OK but sometimes on low RPM while idling would skip a firing on a at least one cylinder making spufff like sound. I put new spark plugs, and wiggled a little coil wires. Bike with new spark plugs would not fire up at all. Checked for spark on all 4 spark plugs - no spark., not even an electrical charge going to spark plug. Went back to coils. Each coil (there 2 of them) has 2 spark plug wires and 2 ignition timing signal wires connected to them. I realized that these ignition timing wires contacts are corroded to the point they would not conduct a charge from the distributor to coil. CLEAN ALL THE TIMING WIRES Contacts on the coils. I did that and bike fired up right away and started running much better without sputtering or skipping a cylinder firing. SO DISCONNECT ALL THE COIL WIRES AND BRUSH THE CONTACTS WITH A SMALL METAL WIRE BRUSH.
I had the same problem with my 2006 Vector. Blown 4 CDI units. Changed out complete wiring harness and Stator, new plugs, Carbs. We narrowed it down to the coils. They were for an RX1 (based on the part number). swapped out with OEM vector coils. installed new CDI.. Sled is running flawless now.
Check the wiring on the connector plugs make sure all the wires are the same color on both sides, red to red blue to blue and so on. I had the same problem After replacing a stator and just plugging it in,after two weeks a new cdi and coil i noticed there were two wires transposed.
did the bike stop when riding?
if you have no spark to both cylinders it will be the CDI box , pick up coils or wiring
If you can give me more details on how/when this problem happened i can help more
if you get a small voltage(1-2v)from you pick-up coil then this should be ok,CDI requires to test your supply to it ie:12v etc and your voltage from pick-up and obviously supply out.If you have these voltages coming in and nothing out then your unit is U/S but one thing to make sure of is that you kill switch wire is not earthed out at the unit.
The voltage on the green wire must be pulsating when cranking/starting the bike, not steady. Confirm by similarly testing the voltage on the black wire on the left ignition coil. If the green still reads a constant voltage, then the CDI is faulty; to be more specific, most likely that the switching tansistor inside the CDI that drives the right ignition coil has shorted.
follow the plug wire back to the coil and see if there are any breaks, if not might switch coil with the other one and see if the other plug now misfires, if so replace the coil, most cdi problems are not intermittent, typically they either work, or they dont.
