Re: Outboard question but not antique

Well, I reviewed the 1980 manual today, it said acceptable charge coil running output is "230 volts or higher". There was nothing saying anything about voltages that were too high, so maybe 400 volts is OK. The meter is supposed to be set at "negative and 500 volts" in 1980, I don’t think that setting changed until 1988-89. I’m guessing output would have decreased as RPM increased.
Your home made break out box sounds fine as well. Let us know how you make out with the replacement powerpack.
