Hello I have an 82 FL250 can someone tell me what the exciter coil ohm reading is? the manual says mine should be 245 ohms in mind reading 218 ohms is that good to run or is my exciter coil no good? |

Welcome new guy. This site is slow so you have to wait for answers sometimes. I'm not an electron mechanic but my opinion is that's it's good. The guy to ask would be adnoh. He's not logged on right now. Hopefully he'll see this post tomorrow. If not PM him. You click on his name and there will be a PM button. PM -- private message. CO |

Good question Russbuss, First: What was the ambient temperature when your too the reading (70 - 80 F pretty standard), Second: Was the Engine still in the machine (may have a multi ground connection effecting reading).Third: Was your meter zeroed out and what is the tolerance of the meter. The reading is so close however out side a 10% tolerance. So temperature effects the reading, solid good connection of the leads to a clean surface at the connectors can effect the reading. Then factor in test equipment tolerance. Some have 1% some have 5% and some 10% etc. If all is good with the parameters of the test tan I say its a fail on resistance. One other item to consider is if it as already been replaced with an aftermarket unit which we have no info on the resistance value. Related to above is the book does say if you have continuity between the black/red wire and the ground the exciter coil is normal. So with that I would say it would be fine @ 218. With that being said you are working on the ignition portion of the system, correct. If so the resistance reading impacts the voltage input to the CDI (Capacitor Discharge Ignition). I would than go to the CDI (Capacitor Discharge Ignition) and test between the red/back and Green connection at the connector plugging into the CDI (Capacitor Discharge Ignition) for a resistance reading to compare to you base reading. If good than check CDI (Capacitor Discharge Ignition) as listed in book. One final note is the ground connection on the stator plate. If you have it off the machine you can check each connection point to be sure its good. Also check all leads from the plate as shown in book. Also look in tech section CSI fl250. Maybe put link there to ere for others. These type of items are important to share wit others. Thanks |

Why are you testing? Here is how I test turn the light switch to ON turn the ignition switch ON Remove the spark plug, plug it into spark plug boot lay on the head so it will ground Pull the Engine recoil starter over hard and fast note if you see any light from the headlight it will barely flicker Check the spark plug for spark Its nice to have someone else turning the Engine over and another do the looking if in brightly lit area you might have to shade the light and spark plug to see. |
