Re: datamarine wiring or manuals
DMI Marine just completed a rebuild of my Mast Head Unit(MHU). After being promised it would be returned in 3 weeks it arrived in 4 weeks causing us to miss our Thanksgiving weekend trip. Once it did arrive, I replaced the unit on top of the mast only to find that it did not register the correct wind speed and the cups spun irregularly. Called Steve at DMI and he suggested i 'simply' return it. Easier said than done since it was back on top of the mast.
After climbing the mast again i removed the unit. Disassembled it my self to find that the shaft that the cups were on had a magnet that was dragging on the wires inside... thank goodness DMI tested it before returning it to me (haha). Also, overcharged me for the return shipment- Charged me $87.50 and it should have been about $39.
Better luck to you if you decide to use DMI Marine for your repair.
