Gauges not working
1970 F250, 390/AC, all the gauges quit working, I can't find a fuse for the cluster, cleaned the connector on the back of the cluster, didn't help. Is there a fuse somewhere for the gauges?

Mounted on the firewall at about the position where the clutch pedal would swing up and into the firewall, there is a Fuse Panel with Five of the old Style round glass fuses that look like little tubes with metal ends. The third one down from the top is a No. AGA-2 Fuse which is for the Instrument Cluster Panel lamps. When this fuse is blown the instrument lights go out. This fuse does not protect the gauges. The power for the gauges comes from a little can that looks very similar to a 9 volt battery on the back of the instrument cluster and you will find the exact same plugs as for a 9 volt battery on the circuit board plastic on the 1970 F-100/F-350 trucks. Check for current with a multi-meter on these connectors. You could have a burned out Instrument Voltage regulator....... Good Luck!
