The wiring harness I bought years ago did not make provision for a ground wire. For this '29 K.J. I picked the right side bolt of the two battery box hanger straps. The bike has never been through judging so I've never gotten official confirmation of that choice of location. See picture.

Attached is an owner's manual pertaining to 1929 Streamline
and DeLuxe model Hendersons. The wiring diagram is dated 3-
21-1929. It simply shows the negative battery terminal
going to ground. The earlier DeLuxe wiring diagrams are as
Gene stated however they show the negative lead going to the
ammeter then grounded to the frame but didn't specify the
attachment point. As they were going through the ammeter,
the attachment point for those models was most likely under
the dash.

I don't know about the KJ but Deluxe and Series 20 X used
ammeter as the ground connection. A wire ran from the
- terminal to the longer insulated stud on the back of the
ammeter, through the meter to the shorter non insulated stud
on the back of the meter. The ammeter bracket is grounded to
the chassis through the lock washers and screws into the
frame. This was standard from 1920 at least until the "dash"
assembly came out, 27 ish (?) Makes sense to do this because
it saves about 3 feet of wire per motorcycle so if you made
5000 machines that year, that's 15,000 feet of copper wire
saved. Schwinn was a miser......

finishing up my KJ project. can someone tell me where the
factory connected the ground wire from the battery. we are
looking at the seat mount bolt, or if it should go
