A simple battery test for a PS1 is to power it up but leave it in "reset" mode (don't hit the direction button to move it). let it idle like this for a few minutes at 12 or more volts and then shut off the power. If the engine completes the 7 to 10 engine shutdown sound cycle and you hear the faint "popping" noises afterwards, the battery is charged and the engine is ready to run.
ok, I will try this. Also, I bought this engine off some guy on Facebook marketplace who didn't mention anything about a 9V battery. Would i have to put one in? I've heard of people putting large capacitors in the PS1 engines to stop the circutboard from being fried.
