I'd still like to have any useful information regarding why I cannot make
changes on my NOS replacement controller, but there's a bright light and I'm at
the end of the tunnel. I felt I had little to lose, so I pulled the
conveniently-modular logic board from the non-working controller and inserted it
into the NOS controller. Great googly-moogly! My calibrator shows all the old
figures, and allows me to change them, but I only went up one value and back
down, so as to not disturb the balance of the universe.

Wonder of wonders, my reverse and my forward selections work and work quite
nicely. I added a bit more thermal grease between the controller and heat sink,
so it might run a bit cooler now.

Ever since I was a tyke, I was taking things apart. I'll bet that's a common
trait amongst us EV people. Some of you were probably better at putting things
back together too. Not so much for me. I managed to rip what looks like a
voltage regulator from the board, destroying the legs, but not the board, so
that's an easy repair. In the process of taking the controller apart, I
discovered that movement resulted in rattling noises. No smoke or mirrors, but
there probably was smoke at one time, because another electronic device
resembling a voltage regulator has lost part of its "shell".

There are lots of these voltage-regulator-resembling devices clustered around
some healthy blocks of aluminum, which are attached with the aforementioned
thermal grease to the backing plate of the controller, no slouch in the mass
department there either. It would appear that I can replace the two that appear
destroyed and probably will replace all six on that string, if I can locate
these devices.

The large banks are composed of the same device. On the left side is a logo, a
stylized ST with ordinary typeface following, reading:

30M233
MOROCCO
P75NE75
FP

The single broken device, as a result of some ham-fisting (what an expression!)
reads:

H J
F15030 (or) F13030)
ON (in a circle) 126

I'm at a loss to understand what these markings represent. Any references or
suggestions would be great. I'm a big fan of DigiKey and Mouser, but not sure
what to input to find these goodies.

At least now that I'm no longer a tyke, I should be able to put all the parts
back together again, perhaps even to have it working. The logic board and
calibrator part is a mystery and I'm hopeful some Sevcon guru out here has an
answer.

We now return you to your regularly scheduled programming currently in progress.


thanks

fred

The part,
http://www.st.com/stonline/stappl/productcatalog/app?path=/comp/stcom/PcStComOnLineQuery.showresult&querytype=type=product$$view=table$$orderable=yes&querycriteria=RNP139=1165$$rpncode=64783

Actually in stock at Digikey,
http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=497-2788-5-ND
It's made by ST microelectronics, 75V, 13 mOhm MOSFET
These would be the power switches in the control.

The other part is made by ONsemi.
I'm not sure what circuit it's on, so I can only guess what it's used for, could
be this,
http://www.onsemi.com/PowerSolutions/product.do?id=MJF15030
MJF15030: Power 8A 150V NPN
http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=MJF15030GOS-ND

If it doesn't look like the part on that link, provide more information and I
can figure it out for you.

Thanks to all who have answered my query about the destroyed parts inside my
sevon controller. The parts are ordered and I'm looking forward to getting out
the soldering iron again.
