You should have a mesh ground strap from the rear of the head to the
firewall for the most stable system. You also might have a wire from
the battery to the firewall instead.

If one of those is dirty, you will get intermittent issues.

The wipers acting like they are likely means the windshield hinges don't
want to be a stable ground for the wiper motor anymore.

My CJ7 pulled this off in the middle of a swamp 1000 miles from home and
3600 miles left to get home.... When I figured it out, I just added a
ground wire to the case of the motor and it has been fine. The CJ dash
usually has a main ground for dash lights and things under the steering
column just inside the rail. That works if the dash is properly
grounded.

Do you have a multimeter? If so I can tell you how to test for grounds
via voltage drop.

Here is a good page on figuring out the gauges:

Ground paths on CJs: There should be a cable running from the negative
terminal on the battery to a bolt on the driver-right side of the I-6
engine block. There should be a short cable that jumps aroud the driver
left engine mount, from a bolt on the mounting plate to the center bolt on
the bottom of the rubber mount (engine to frame ground). There should be
a woven web ground strap from a bolt on the block (sometimes the top
center bellhousing to engine bolt, where you can't see or reach) to a stud
on the firewall, immediately behind the valve cover on the I-6 engine (the
stud is actually the left-most mounting point for the heater box). This
would be the all-important engine to body ground. If this one is AWOL get
a new one from your favorite autoparts discount retailer and attach it to
the firewall and to the engine. On the I-6 I'd pick the bolt that
connects the bell housing to the block, just driver-right of the row of
spark plugs. It is fairly easy to get to and nothing will fall off when
you loosen it. Don't try to fab a jumper out of primary wire: It has to
be big enough to carry all the current when you have everything (lights,
fan, radio) running.
