I decided to hook up power to my Rebel last night. I have a small portable
starter battery that I use for my RC stuff and starting cars in the winter if
their battery is dead.

After connecting everything up, I flipped the master switch and nothing?

Does this solenoid need a certain amperage battery to toggle when turing the
master switch?

They generally draw about an amp after closing! If your battery will
boost a car it will be more than adequate.

There are different versions of contactors so you might have to check
that you really have 12 volts across the coil.
1. Both coil terminals brought out to terminals.
2. One end of the coil connected to one large terminal in which case
that specific large terminal must go to the battery and you'd ground the
small terminal to activate it.
3 I think there is also a version with one end of the coil internally
grounded to the metal case of the contactor in which case it needs +12
volts on the small terminal
4. then there are momentary use starter contactors that will draw
several amps. They will overheat and burn up if used as a battery contactor.
