Hello, I have a 1992 Force 40HP motor. If I turn the key, the motor will turn. If I engage the choke solenoid, the choke will engage. However, if I do both at the same time, the choke will engage, but the motor will not turn. I hear a one time sound as the starter tries to engage, but it won't turn. My battery terminals are clean. I tried individually running a positive and negative to the motor using a jumper cable to ensure that it's not the main power cables. Any suggestions? Thanks.
