Bought this older tractor last fall and it worked fine. Removed the batter
y for the winter, and wanted to reinstall.
When I looked at the install spot, for the life of me I couldn't recall if
this was a standard negative ground. My first tractor - previous cars and
motorbikes were all negative ground, but when I tried to find a manual or s
pecific indication online, the verbiage said "if you have a model with nega
tive ground...", so I was leery of installing wrong.
Can anyone confirm?
For what it's worth Jaguar was the last automotive company to
change back in 1969. I think farm tractors changed about when they
switched to 12 volt systems but don't know for sure. It would be back
in the mid 60s. There is a farm forum called yesterday's tractors.
There might be some help there.
The bolt lugs are the same best I recall...
The obvious is as you say, check the molded polarity indication on the case.
_But-, there are two U1 case orientations--a U1 case has the positive
terminal on the left looking at it from the direction the terminals are
nearest you. U1 or U1R type battery. U1 will have the positive terminal
on the front left. The U1R(ight) will be on the right oriented the same way.
I don't recall otomh which either of the two JDs here are or the
previous two before altho I believe they're UR.
