PICK UP COILS

OK I'm sure this is a dead horse around here but I'm still green to this site
so first off the bike was running and sounded good but #4 was not getting hot on the pipe the next day bike turns over and won't start
Battery reads 12.6 volts right now
readings for the coils fluctuated like crazy in the high 17000's so got another set with warrenty and saw vid of the bike they came off running
still not starting
Now I've checked the pick up coils
You can see in the pic's what my readings are on the meter and how it's set
ARE THESE NUMBERS GOOD FOR THIS BIKES PICK UP COILS?
AND ANYTHING ELSE I SHOULD CHECK? I'M SCRATCHING MY HEAD AT THIS POINT

1982 XJ650RJ Seca (non-yics engines): 700 ohms +/- 20% = 560 ohms to 840 ohms acceptable range

1982-84 XJ650 Maxim: 650 ohms +/- 20% = 520 ohms to 780 ohms acceptable range

1982 XJ650RJC Seca (yics engine): 650 ohms +/- 20% = 520 ohms to 780 ohms acceptable range

1982-83 XJ650 Turbo: 120 ohms +/- 20% = 96 ohms to 144 ohms acceptable range


Ignition Coils:

Primary side (input from main wiring harness):
2.5 ohms +/- 10% = 2.25 ohms - 2.75 ohms acceptable range

Secondary side (spark plug wires, without their end caps):
11K ohms +/- 20% = 8,800 ohms - 13,200 ohms acceptable range


Spark plug caps:
5K +/- 20% = 4,000 to 6,000 ohms per cap acceptable range

Spark plugs:
0 ohms per plug

 

Thank you so much Chacal so based on yr info my system checks out to be functional and I have brand new resister caps and the battery is new as well as all the safety switches check out
so I guess this means my CDI OR TSI BOX gave out huh?
Robert
P.S the bike is a 1982 maxim 650
Thank you again

 

Oh Polock
I bought this bike for $200 more than I figured it was worth with the Ideal of making it road worthy and doing a café/street tracker style set up on it painting it and selling it for a small profit as making choppers n bobbers out of unloved and badly treated older jap bikes has been my hobby sense I became disabled but this one just struck me as a good café or tracker candidate
So I don't have a manual for this model friend

Before you condem the TCI be sure the ignition cut off circuit is working. I think its the black/white stripe wire on the TCI connector. That wire should NOT be grounded. I had a bike one time that had that wire grounded in the wiring loom and it drove me nuts finding it.

 

Check out this write up it helped me a lot

Number 4 cylinder being cold, can you confirm the float level is correct? How old is that battery by the way?
