I recently bought a mega si for the console and also bought a mega di
for the bow. I have the terrova so I exchanged transducers for the
trolling motor. They told me the universal sonar would conflict with the
one that came with it. Anyhow, I powered it up thru the switch panel with a 5
amp fuse. It powered up and I got on the lake and it was not detailed at all.
I also used the cornfield crappie saver for the cord from the transducer.
Could it be I need to run straight to the battery?
