Many moons ago, I posted about a problem with my Gizmo, which was eventually
tracked to the controller. The MOSFETs within were physically damaged and I
thought I might effect a repair on my own. Desoldering the very first device on
the board was nearly a failure, due to the conformal coating on the board. The
second device proved more resistant, so I stopped prior to creating any damage.

I contacted Sevcon and was told they do not repair controllers that have MOSFET
damage, so that's out the door so to speak. I've since discovered some of the
exact same controller on eBay and purchased one.

The question to the forum, is there anyone who would like to have this blown
device for hobby purposes? The cost of the replacement MOSFETs would run nearly
a hundred bucks from Digikey and of course, the reliability would be in
question. Not exactly glowing praise, is it? I'll send it to the first person
to ask for it, for the cost of shipping, probably about seven dollars or so.

One more caution, the logic board is locked out of being programmed. That could
be a project stopper unless you have the means to de-program it.

Fred,
You may have seen me on the EVDL as I post several times a day when I can
enlighten others. We would love to have your blown controller for use as a
"Static Display" for use in the classroom as an example of EV component
internal construction. For that purpose the equipment will see a new life
and is far better than a photograph to improve trainee learning.
Also any others who have bits of defective units not worthy of repair
we will accept them and use them for training aids, if you want to see them
have a better purpose than scrap metal or trash drop them in a flat rate box
or envelope and include your contact info (Pay-Pal ; or name and address to
mail out a check). For shipping reimbursement !
