Replace speedometer cable on 1986 Honda Prelude

A bouncing speedometer is usually the sign that the gear at the transmission end is worn out.

speed stick just ask for that at autozone

sounds like you will need to replace the starter.

Your speedometer-cable is broken.
You could replace it by disconnecting it from the transaxle, and also from the back of the speedometer itself. (disconnect the battery before you do this).
You will need to remove the instrument cluster to be able to get to the speedometer-cable at the back the speedometer.

no there is no easier way if he didnt put the pin to the cable back on it must be reattached

Probably the Vehicle Speed Sensor (VSS). Cheap and easy to change (see ebay), once found! Probably on top of gearbox, to rear.

may be alternator is on its way out. replace bushing.

Bad relay. Locate and replace
