Measure the resistance of coils ?

[velvetrider]

I am down to them. The false tank cover is off. the air box is out. I am still trying to figure out how to remove them. How does one go about measuring the ohms which pass through. I assume it is from one of the colored wires on top, to the output of each. Is this correct?

Quick answer... don't have detailed specs....
Secondary winding = 20k Ohms from sparkplug wire to sparkplug wire (including the plug wires themselves), and has NO connection to ground.
Primary winding = about 0.5 ohms, black wire to colored wire.
I can't remember if this should include the ballast resistor wired in the black wire (12 v supply wire to both coils).
Just check both coils... they should agree with each other and be very close the the same readings on both.
Mine is a 1980... possible that your '83 is different ??

Glen ,, I measured 1.2 ohms for right Primary coil. and 2.2 for left Primary coil. My Service book says primary should have, 04. +/- .004, I couldn't get a reading on the secondary coils.. I am going to simply measure each # 1&2,, for right coil. and 3 & 4 for left coil. Clearly there is something wrong with the right hand coil. I will verify tonight when I can see the spark better at each cycl.
Thanks.

After basically removing the coils. I am thinking a newer 1500 would look better in my carport. Got any suggestions,,???
Thanks Guys.

Be aware that single digit resistance readings are below the noise floor of a lot of multimeters. Unless is has a specific lo ohms range, or uses a four wire measurement, take the readings as a general ballpark. If a coil should have 4Ω and you read 2Ω, no big deal. If you read .4Ω or 40Ω then I would be concerned. Also you will need to zero out your leads for low readings.

that is why I have held onto my Analog meter with the mirror scale, and a very low Ohm range.
