Case's were negative ground.  I don't know why.  The starter doesn't care
which way you hook the battery up.

Just to make things interesting I will mention that the DC4 Case manual
states that the electrical system is 6 volt negative ground. This was even a
surprise to me after all the years of Cockshutts and old Ford flatheads
running 6 volt positive ground.
Its been a long time since I put a 6 volt battery on that DC4 though. In
fact I can't even remember which terminal I used for ground. Lately , when I
get inspired to try starting it again I just put a 12 volt battery on and
spin the motor for a while. Wonder if I had the battery hooked up backwards?
This might explain why it was so hard to start (turning backwards) :-)

Mike it seemed odd to me also that the "H" would be factory wired for
negative ground.  As far as I know about all engine powered rolling stock
was positive ground until the advent of the alternator.  Our 66 JD 3020 ---
12 volt was originally equipped with a generator and positive ground.  It
has been running with an alternator for the last 20 years or so and is
negative ground

Re:[AT]desulphatingbatterychargers

I don't want to get into one of these ATIS endless pissing matches, Jerry,
but I would be very interested in seeing a scan of the IH manual for the '41
H that shows negative ground. My manual for my '41 H shows positive ground,
as does every IH manual I have seen for tractors until the mid '60s when
they went to 12 volt alternators. And, it seems to me that every other 6
volt machine I have encountered came out of the factory wired for positive
ground. If I am wrong about this, I would appreciate being set on the right
track, as I have told a lot of people that their old 6 volt machines were
positive ground.

Mike
