New to this group, thanks to everyone.
I have a 2003 Johnson 90 2 stroke J90PLSTC. Last season I replaced a faulty volt regulator with a CDI 193-6048 unit. All fine last season. But this year both charging and tach are randomly intermittent. Engine runs fine. Some times it's not charging at all, then charging around 14V, then jumps to 17.5V sometimes all within a few minutes of each other confirmed with DVM. The tach may not work at all for awhile then it's fine and may jump around as well, with no relation as to what the voltmeter says. Sometimes everything may be perfect for several hours.
I have rechecked every connection I can think of including battery connections and a new battery. Is it possible the ignition switch could be at fault? Stator?
I went to Johnson outboard school back in 1977, but I'm afraid my handyman skills are not what they used to be.
Any advice if appreciated.
