Make sure you have a strong battery! The starting current is huge.

AH, the olden days! I used to have (still have a couple
laying around) a DM35 running my mobile Lettine 240.
It would dim the headlights at first keyup. I popped a few alternator
diodes, too, until I went with an extra battery and heavier alt. I wouldn't
want to trade those
days for the new, but it's fun to remember.

Some years ago, a ham buddy and I were scrounging around in his storage shed
and ran across a BD77 dynamoter unit--1000 volts @ 350 mils (I think)---.

"Hmmm, I wonder if it will start".

We carried it into the shop and hefted it up onto the workbench (sucker was
heavy!), and hooked it to a
surplus 150 amp supply. After all those years, we forgot
about the startup torque on one of these bad boys and touched the positive
terminal. The dynamotor proceeded to JUMP off the table causing us to go
into a dance of
the wayward dynomotors! We both were hopping around the floor frantically
trying to keep the thing off our
feet!! The torque was terrific-way more than the old DM35s I was used to.
We put the thing back in the shed and I think it is still there today!
Yeah, yeah, I know, we
should've anchored it down! LOL!
