Have a 2014 Basscat Eyra w/250 Mercury Pro XS. The smartcraft gauge is part of the tach and it went nuts, changing modes rapidly. After playing with the mode buttons, It finally stopped changing modes, but then displayed the following... T1 403, T2 402.7, T3 402.7. At one point, it also showed a symbol like the connection was broken. In troubleshooting, I found a badly corroded plug and harness receptacle coming from the separate mode selector switch that Basscat uses. I cleaned up the connection the best I could and the broken connection symbol went away on the readout, but it now reads...T1 0 w/arrow pointing at this, T2 402.7, T3 402.7. I don't know what this means and if it is a matter of resetting the gauge, how is this accomplished? Any help would be appreciated.
