Hey there folks!
I ent to the boat this afternoon to check the engine out and inspect the electrical system. Upon removal of the Voltage/Charging regulator, I discovered that I have indeed fried it to death (complete with smoke and char!!!). I have some pictures that I will try to post here, but basically, it is shot!
Now my questions are:
can I find a replacement for this unit...are there solid state regulators that are compatable? Has anyone else done this replacement before, and if so...how did you do it and what unit did you use. I sure could use some help with this one!
The other question I now have is, is this just a symptom of things that are wrong further down the line, like with the dynastart or bosch alternator..etc....? Could there be a problem with the wiring??? I am just not sure why it decided to quit when it did...but then again...it is 30+ years old...
thanks for any suggestions or advice that you might have concerning this.

You are getting beyond my experience level on the vega...
But where is this regulator? Is it in the electrical compartment or in the alternator?
The dynastart puts out DC already since it's a generator. So it's probably not involved in this setup.
The alternator puts out AC and is more efficient, but it needs a regulator to help turn the AC into DC.
In my boat, the alternator is not original. I only have the dynastart set up as a starter and don't use the generator function.
The alternator is what charges my batteries.

Hi Chris,
if (as I do) you have an external regulator (ie reg is physically separate
from the alternator - obviously electrically connected) then no problem
replacing it.
When I realised that my alternator was not charging the battery I took my
reg to a small car and van repair place. He tested the reg and found a
second-hand replacement for about 50 Euro.
This was 2 years ago - no probs since.

Hi Chris
The aluminium box is indeed a combined regulator and starter solenoid
for the Dynastart. You can replace with a separate solenoid and
regulator or obtain a 2nd hand original (Contact me off board if you
want an original). There was a thread a few years back on changing for
new separates but cant remember who it was!
The Dynastart does still need a regulator otherwise you would be putting
large voltages into your battery.
Cheers

Hi Steve,
I rarely know what I am talking about - still less what others are...
I did find what (to a layman) seems a nice article about the Dynastart
regulator setup:
All the best,

Hi Roy,
I believe that this is what the system is on our boat, but the wiring is very confusing to me. The regulator is in the electrical compartment and the original diagram from the Volvo Workshop Manual calls it the charging regulator.

Hi John,
I wish that I knew more about what I was talking about so my descriptions could be more accurate and helpful!
I truly appreciate all the help that everyone has offered with this. I hope I can get it squared away!

Hi Chris,
bearing in mind Steve's comment - can you trace the wires coming from the
regulator?
If one of the wires connects to the alternator - then imho it is a
conventional (external) current regulator and easily replaced.
If it is connected electrically to the Dynastart then over Steve and the
other experts..

Hi John,
I believe that is how it is connected. There are about five connection points in this regulator and it appeared as though two separate points were used for the alternator and the starter. A few of these connection points are piggy backed and it looks like spaghetti, but I think I will just have to bite the bullet and sit down with a notebook and trace back all the wires and create a schematic that even a dolt like me can understand!!!

I stand corrected on the possibility of a dynastart Vreg.
I was thinking about that last night as I was trying to go to sleep...
oh well.

For anyone that might have performed this "upgrade" of using a separate solenoid and regulator for these units...might you have any information on the parts that you used?
Looks like I will try the original unit first and see what kind of luck I have with that. Do you think I need to go through the trouble of pulling both the starting generator and alternators to have them tested, or is there a general consensus that this simply was the end of a very fulfilling 35 year life of my charging regulator (RIP)...

If the regulator isn't to much money, I'd just replace it.
Turn on the key, listen to see if you get that buzzing racket again.
If so, turn off quickly and keep hunting.
Did you decide that your batteries are ok?

In general, things that can make regulators hot..
If it's all burnt up...
Then maybe the input voltage got high and the regulator still regulated the output to like 14 volts or so, causing great amounts of power (heat) to dissipate in the Vreg.
-or-
If the output got low impedance (short?) (old battery shorting out? But the battery volts would be very low.), again great amounts of current would be asked of the vreg causing lots of heat (power) in the vreg.
This is assuming a linear voltage regulator.
The above are things that can make a good regulator burn up. But sometimes they get old and break on their own too.
I don't have the circuit diagram, but I am wondering what could have caused the chatter in the starter relay when the key is turned?

Did it chatter just when battery power was on and starter not engauged?
Or did it chatter only when you turned the ignition key to start?
Did you let it chatter for a long time (1 minute may be long)?

If you change the regulator, and if it starts buzzing again..
Maybe you can use that buzzing as a troubleshooting monitor?
Start disabling (remove from circuit) or substituting things, til the buzzing stops.
Make sure the circuit is still functional after you bypass or remove a part or it will stop buzzing because the circuit doesnt work anymore..

Hi Roy!
Yes, the batteries are "A-OK". I put the meter to them yesterday and they both checked out fine. I am currently only running one battery as the previous owner only ran one and there is only enough room for one under the floorboards for two...that is another project for another day.
I have contacted Steve and will be trying out the 2nd hand original that he had in stock. I will run if for a short while, turn her off and see if we have any smoke!
