It should not be carrying 2 amps. With the Rotax you only
have 19 amps to play with. If your solenoid is designed to
actually use 2 amps it is unsuitable.
I used a "rally/race car" master switch (red in colour) as
the battery cut off in mine. It uses no current to
activate itself !
Then if you want a master switch operated solenoid for the
non-starter battery current then a much smaller one can be
used - with a max switching capacity of about 25 - 30
amps. I have seen such which only use 0.1 amp for their coils.
