Hi,
I searched the forum including the 101 basics about electrical topics, but I'm left with one question.
After a lightning strike into the mast antenna of my Catalina 30 (1985) fried/destroyed all electronics and the some, I'm back running. The old Weems&Plath Automac's part looking like a large transistor had exploded, as did several fuses and the AFS 70 filter. But it looks as if my alternator stills works!
Trying to make sense with the wiring, I made diagram 1 as it was (the white wire was "ripped" off from the automac (I think)).
Diagram 2 is as it is now. I took the Automac and AFS70 out, but I'm left with that white wire,
From my understanding this is the field wire, used to control the alternator output.
If I start the engine, the alternator output voltage is zero. If I then put +12 V on this white wire,
the engine RPM'ss goes down a bit and the voltage rises fast to 14 and higher
(I disconnected it immediately ) So I assume the ALT is still working?
What is the cheapest way to get it to work normally ?
I found the SPACREEK Automac manual and alternator file, but I might be to stupid to make sense of it. It seems I can rewire the old regulator "back" to "normal" ? Or can I use an external regulator, as I believe the Automac was something like that ? And if, something cheap like a car regulator or do I need to for some hundreds for these Balmar magical thingies ?
Any help is appreciated !
