Just bought this a month ago and the gauges wont start working until driving the boat for 5 minutes or so . Perfect pass works the whole time so the boat is useable as i wait for the rest of the gauges to pop on. The last two gauges take a while (oil pressure and voltage). So i was thinking it was a corroded connection. I cleaned all the battery terminals and the connectors at the gateway box. I dont know where the grounds are for these as i want to clean them up as well. Dont really know the cause so im kinda trying to figure it out myself. Have not changed the batteries in the boat, it starts and runs fine. I guess i could try that next. Read some stuff about a gateway box but im kinda hoping to figure it out before going that route. Any input would be appreciated.
