    Honda BF8A No Spark

    GREAT advice man. Very likely that I cannot be sure that I had enough RPM, so will take this advice and start over there. Disappointed that the impendence check didn't work out, as an electrical engineer, that was the easiest test for ME to confirm a good spark should be present or not...

    so as background, I'm an electrical engineer, so I know a little bit about ohm meters and impedances. this test document you provided, which I also found somewhere, is faulty. Hard to understand too. It actually suggested too that they 75/100 has the same CDI. Is that what your manual...

    good advice. i'll retest. The coil tested about what your numbers from what I recall. I tested pulser and exiter per some $50 access to info on boat us or something. Will retest those. Don't know what spark gap. Just boat new and installed per specs. son did that, so not sure they were...

    Honda BF8A No Spark

    "I have an old B100/B75 series (10 and 7.5hp) shop manual and there is a two or three page supplement at the very back for the BF8A so they are very similar to one another. I can look there for some things like resistance and volts values and get back to you" Sill looking for document to test...

    Honda BF8A No Spark

    anyone know where to find a CDI for this? found on ebay, but they guy won't provide any testing verification; he only says "it worked when i took it off" and "no returns/no guarantees" hard to shell out $200 he wants for a $500 motor if it was working....

    So, FYI, there is no way to check wires to CDI on this unit, as it is potted. :confused: I'm starting to suspect that is the issue.... I guess I have to spring for a $50 manual to find out how to test the pulser and coil. Other than those, the wiring diagram clearly says it would be a CDI...

    where do you find the wiring diagram? good stuff. So the neutral switch issue is just an adjustment? I do think that someone replaced the coil trying to figure it out and then maybe gave up..... looks like not original. but tests ok. No wires are unplugged that I can see.... Yeah, didn't...

    Honda BF8A No Spark

    Thanks! I completely disconnected it and no spark. Same as kill switch. I do not know how to test other components in the ignition system. Usually in something like this I'd find a bad switch or something obvious. I still think I'm missing something obvious...... How do I know which...

    Honda BF8A, SN BZBC-1401877 First I cannot find the exact parts diagram for this sn. Anyone that can please link; thanks. I looked for posts here for "spark" but find little on this model. I have the proverbial "no spark" issue. Coil good. Pulled flywheel and everything "looks good", i.e...
