Waid, I purchased a Toyota Prius motor and computer box. When hooked up to a battery, the computer sometimes clicks once and the motor will operate only for about 2 seconds and then shuts off and I then have to detach and touch the ignition wire again to the positive pole of the battery to get the motor to operate. Sometimes when I connect the ignition wire, the box clicks twice and I get no motor movement. Bottom line is that I do not get more that a couple of seconds of use out of the motor before it quits working again. Note, I am using motorcycle battery and am wondering if that could be the problem. Any ideas from anyone?
