I concur.
wondering if the poster was reading full starter motor current ..( but that
would be more like 100 to 150 amps....though with no load, 37 amps would
fit )
and not just solenoid energizing current ..
which is all the ign switch sees of course.

6 amps sounds about right I'd say,.

I have seen many cables from solenoid to starter motor ..
it's a small cable ..I've seen lots of those that looked overheated.
it's normal.
one should never crank continuously more than 8 or 10 seconds or so anyway
though.
It's all about being easy on the equipment to me. ..that and taking good
care of it.

I'll sure have to say ..
Bosch is good at making starters ..
a good original type one ....good for years and years and years.
