VDO log stuck at 0.0
My newly purchased '76 westerly tigers VDO log is stuck at 0.0. I had the boat hauled out and we cleaned the prop of shells and it spun correctly. The panel turns on but just sits at 0.0 when moving. All the wiring looks fine from prop to panel. The back panel has a series of small switches but have no idea of the correct configuration. Any other troubleshooting I can do? Ta!
