When revving the engine there is a screeching coming from flywheel area?

New to me the vehicle listed above with 225 dauntless. It has fender starter relay (three prong) and a piggyback solenoid on starter. Starts and idles perfectly, then turn off with key. However, when at idle if I rev the engine a few times there’s a horrendous screeching coming from flywheel area and turning off key engine continues to run (returns to idle with screeching) resorted to removing negative battery cable to stop. If I start again, idles perfectly. Tried putting transfer in N, pushing on clutch during noise, replaced starter/piggyback solenoid, new ignition switch, new fender starter relay. After removing battery cable to kill engine after screeching event, notice a tick, tick, tick, from flywheel area that fades out. It sounds like when cars just get hot after running but this sounds too regular. The car runs cool by the way, no overheating problem or anything. Can’t find a diagram for 225 with combo fender and starter mounted solenoid. Maybe something’s wired wrong from po? Sketched wiring if decipherable by someone and will try to attach. Any assistance appreciated, Gary
