The Honda manual does not give any voltage readings, everything is in ohms. I don't know what output would be at cranking speed. I believe rpm,s have to be at certain speed for the field to excite before producing current for charging but the exciter coil should produce some voltage probably very low and I believe it to be ac but some of the 250 stators were dc so you would have a dc current in that case but some current should be produced by the exciter coil which would be the one larger coil on the stator and is usually insulated unlike the others with exposed copper windings. The exciter is what puts power to the Ign. side of cdi. My guess is they check these units measuring ohms instead of volts since you can have voltage but if too little or too much resistance is present it may not produce the voltage. Your magnetic pickup you say reads 110 ohms which is within the range of 50-170 ohms Usually the exciter wire is black with a red trace. Use RX1 to check this wire.
