So last night I was able to successfully start my once basket case of a bike. Today was another story.
Last night I was able to get running my '82 almost too easy. Even though it did not appear to have the strongest spark I've seen (on other types of engines) it did spark, and it did start pretty easy. I ran it several times last night, and once the carbs were tuned a little bit, she would pop off almost instantly (bike apparently had not been run for several years)...
Today, went to start it and not a pop, nada......
Here is what I have, '82 with 7 pin tci, cut down wiring based off of several of the simple wiring scematics from this site, along with a TC Bros simple wire kit. I added electric start to the system. I made sure to keep everything simple and fused the lights, ignition, and brakelights each with 10A fuses and then the main I fused with 20A
Everything works as it should. I have (2) TCI boxes that were both good yesterday, but both do the same thing today....no spark or just one set of sparks during the initial roll over, then none.
I suspect the main ignition coil as I can get no resistance at all when I connect my meter to both of the plug caps, I understand it should have about 11K ohms, and to add both of the 5K caps...strange how it worked so well last night, then just over night it's open. This looks like the original coil (hopefully for this bike).
The other thing I checked was the pickup coil. I get 702 ohms from the orange wire to the black, but nothing from the gray to black. I checked for a broken gray wire and it appears to be ok...I'm assuming one of the advance coils in the pickup is bad. Does the gray wire act as an ititial ignition signal or is it the advance signal...I assume if one of the coils is bad it would still run (or at least spark)?
Not sure why both coils (main and pickup) could suddenly take a dump.
I do have a key with a starter button. The key switch is a on-off-on type. I have it wired so I have ignition on one "on " side then both ingition and lights on the other "on" side. Could I possibly have gotten some kind of spike starting the bike only on ignition, then swing it thru the off position to lights?
Checked all grounds and connections, however motor is just currently sitting in the frame, all bolts are installed, but nothing except one frame bolt is tightened up. Could this be not fully grounded?
Anyway, any help with my long winded post would be appreciated.
Thanks, Tom
