85 on the relay is a ground.
Today I cleaned all of the ground connections. Replaced the positive battery post with a gold plated post. Replaced all fuses and took a wire brush to the fuse box. I still get a click from the relay when the aftermarket start button is pushed. The connection at the relay for terminal 50 puts out 12.5 volts but when it's measured at the starter, it's 0.1 volts. Hope this helps. Thanks.

Your description doesn't indicate what side of the relay voltage is being measured. Source voltage should be 12v on both the control and power side of the relay.
Output connection on the control side should go to ground. Output connection on the power side of the relay should go to the starter solenoid and indicate 12v when energizing the relay.
Temporarily remove the wire from the starter solenoid, then connect the meter test lead to it. Press the start button and measure voltage. It should be 12volts. If voltage is 0, the relay isn't working correctly.
If 12V and the solenoid doesn't "click", then the solenoid is malfunctioning. If the solenoid "clicks" but the motor doesn't rotate, the motor has a malfunction or the electrical connection between solenoid and motor is faulty.
