my situations is as follows and I thank you in advance for any and all responses:
I have not now, nor never have had, spark on my 72 cb350f, with a 400f engine; i bought the bike used and non-running. I have done the following things to attempt to obtain spark-cleaned/adjusted points, replaced battery, checked fuse (ok), checked kill switch (functional) and since I broke two spark plug wires I replaced the coils. I also have new plugs I have yet to install. They are NGK DR8E, which are what are installed in the bike and called for in the stores reference manuel, though my Clymer suggests NGK D8ESL's.
facts:
-Continuity from batt to ignition switch
-continuity from kill switch to coils when switch is in the "on" position
-continuity between red and blue wires @ ignition switch when switch is in position 1
-continuity between brown and brown/white @ ignition switch when in position 1
-continuity between red and brown @ ignition switch when in position 2
-12.61 @ battery
-11.79 @ kill switch
-11.67 @ coils
-11.6 @ points
Potential culprits:
-I replaced the coils with ones off of an old Honda, which my father said came off of a running bike. The new coils have a resistance of 2.3 ohms whereas the old ones have a resistance of 4.3. Could this be a factor on a points ignition system.
-I get voltage at the points whether they are open or not when I place my ohm meter on each side of the points. I can't seem to get a voltage reading by only placing one of the ohm meter testers at the points and grounding the other out at the engine, though that just might be my own ignorance and not the cause of the problem. Something wrong here?
-maybe bad condenser(s). I need to check those still. Won't any condenser work? I thought I heard that a condenser is a condenser is a condenser, but could be wrong.
-Voltage too low early on in the system. Shouldn't I have more than 11.79 @ the kill switch. I could have too much resistance early on which is why I am not getting any spark.
-Bad ground somewhere. I don't think this is a problem but know that older bikes are fickle about having a good ground. So far they all look decent.
-The plugs I have, since they are DR8E and not D8ESL as my Clymer manuel suggests, could be outside of a range that the ignition could coaxs into sparking.
Any help is greatly appreciated. I am new to working on older bikes and eager to at least hear the sweet bellow sang by these four into four exhaust pipes. Any, any advise suggeestions, theories will be checked out because I simply am running low on ideas...thanks
