The VDO combination time/hours/temp/depth gauge on my '01 Bayliner Capri 195 went wacky after I inadvertently hooked up the negative wire to the positive battery post while changing the battery. The unit now continuously cycles thru all the functions non-stop. The readout funbtion changes every second. I cannot set the clock time but the other info still seems to be correct. I was told by my dealer that a complete new dash cluster would be required at a cost of $1400 and that they are currently unavaliable! Has anyone ever had to repair or replace one of these VDO units and is there a cheaper way to do it? I would like to keep the dash original if possible as this boat has few hours and is in excellent condition. Any help would be appreciated. Thanks!
