2001 Ford F-150 Instement cluster

On hard acceleration or if wheel spin in rain the cluster will peg all gauges and then all fall to bottom of scale. At the same time the battery light will come on as well as the ABS light. The speakers will also begin crackling if radio is on. Bring vehicle to a stop and cluster will reset, lights go out and all is good till next RPM increase. Sometimes only normal start from a stop will cause this. It will however only do this if in gear. You can sit in park or neutral and rev all you want and its fine.I have pulled the cluster thinking I have a bad connection. Resitance check of both connectors while plugged in showed all good connections. I have not been able to get my local ford dealer to let me look at factory wiring book to see what conection is between ABS, Bat, Trans, and radio circuts. Anyone seen this or can tell me if a module maybe sees input from all hese areas?
