Is the starter stuck? If the started bendix is hanging out it'll draw
lots of amps, burn up in short order, and wreck the flywheel ring gear.

PS, I also fly a 1968 PA-28-180 well equipped with lots of electrical stuff
and I can't get over 35-40 A with everything turned on.

PPS, most alternators can provide rated output at "idle" RPM, thus their
advantage over generators. I don't idle my plane at the idle stop, I use
800 to 1000 RPM for better lead scavanging and less vibration.
