Just curious, is there a way I can find out how many amps of 12V power it takes to activate the electricals on this motor? For example, if I want to add a primer switch, how can I test the primer solenoid to see what it takes to actuate it without damaging it? I would like to do the same for the starter and the stop switch. The rig came without a tiller handle, and I bought one of a rope start motor. I have throttle and steering, but no start, stop, or prime.
