    I Got Me a Mercury !!!

    @Scott Danforth Thank you for the link . . . I'm getting to the point of 'had enough fun' with this motor. Something is very intermittent, more 'off' than 'on'. I was able to get a decent spark on the plugs this morning, so I put the motor in the test tank and tried to start it . . . Not much...

    I Got Me a Mercury !!!

    I know . . . exactly. I may try a capacitor, if I can find one with a high enough voltage rating; else it is back to the magneto ignition that I had on the 1969 model. I can see why Mercury had this ignition for only 2 years. . . :rolleyes:

    I Got Me a Mercury !!!

    Yes, I'm thinking that the charge from the stator coils is dissipating too quickly, particularly when I tested it with no coils attached. That would point to an issue with either the capacitor or the electronics module. One issue is that the parts for the phase maker ignition are rare and...

    I Got Me a Mercury !!!

    Well it is a no-go . . . after all the testing and tweaking, it still does not want to fire a plug. The plug tester lights up and I am getting 240 volts peak, but there just does not seem to be enough to fire the spark plug to a reasonable extent. I contrast that to the Evinrude that I picked...

    I Got Me a Mercury !!!

    Quick Update . . . Rainy day, so I decided to do some more testing on the 1972 Mercury. I Took the spark coils off and pull-tested the stator alone to see if I would get good voltage. Looks like I am getting 280 volt peak. (each division on the screen is 40 volts (I was getting the trace to go...

    I Got Me a Mercury !!!

    Thanks @nola mike The schematic looks something like this, The maker points ground the 'spark' coils, the 'generator' coils provide the voltage source. . . I suspect that something may be dragging down the voltage, or the low-speed coil is not creating enough voltage. If I have to replace...

    Although, looking at potential replacement parts, starting to feel like . . .

    I Got Me a Mercury !!!

    My next step may be to check the ignition coils to see if they are shorted or something . . .

    I Got Me a Mercury !!!

    I went back through all of the tests specified in the CDI literature. Here is my test results . . . See the values written in . . . . Everything looks good except the peak voltage from the stator (CDI calls it an alternator). I am only getting 110 - 140 volts . . . maybe some as high as 160...

    I Got Me a Mercury !!!

    I have an oscilloscope, which should do the trick to read peak voltage.

    I Got Me a Mercury !!!

    I need to see if I have a DVA . . . I'm only getting 20-25 volts from the stator using a DVM. I should be seeing 180v P-P from the stator.

    I Got Me a Mercury !!!

    Also . . . CDI has a troubleshooting guide, which I have been referencing for testing. There is one more thing I can try . . .maybe it will will work :unsure:

    I Got Me a Mercury !!!

    OK, I'm not having any luck with the 1972 Mercury ignition (aka Phase Maker). I've replaced wiring, isolation blocks, tested the module, the coils . . . everything seems to be per spec (Referencing the write-up by Bill Mohat) . I am thinking that maybe I should just take the magneto...

    Are there any Xenforo Web App Experts Among Us?

    It seems like many of the Internet forums have migrated to 'Xenforo' software. Just wondering who all may have worked with it as part of their profession or otherwise?

    BMW headlight . . . $1,000 !!!

    Quick update . . . In my search for a new headlight assembly, I came across some seemingly inexpensive replacements, but the fine print was that they did not have any of the 'modules'. As shown in post #25 above, new headlight assemblies with all the stuffing are about $2,700, some places were...

    Loosing Faith in Humanity . . .

    I've only sold 2 items, but your point is well-taken. After all the fees and stuff, I'm only netting about 65% for my sales. I've learned a few things, so the number should go up. I'll just need to figure the net proceeds into my pricing. (I try to under-cut on popular items, figuring that...

    LiFePO Batteries ???

    Quick update . . . While the system has been doing its charging thing while the boat lives on the mooring, I have noticed a few over voltage situations from the solar charging (via the DuoRacer controller). From what I can tell, the over voltages are brief, ( maybe a few seconds or less) and...

    Over voltage (again)

    Quick update on the on-going saga . . . Electrical system 'happiness' has been hit or miss over the past month or so. My good friends on the Cruisers 338 owner's group (FB) said to check the battery isolator, based on their experience. My initial efforts were to just put the alternator and...

    Water in the Lower Unit

    13 psi is plenty, if not too much . . . I'd change the gear lube, go boating and re-check in a month or 2 . . .
