One or two fuel senders for dual helm 2009 MS 34 flybridge
Newbie closing soon on 2009 Mainship 34 flybridge trawler. Upper helm fuel gauge not reading and surveyor thought boat had a single sender unit with a switch somewhere to send signal to upper or lower station. I've seen no such switch nor every heard of a set-up like that.
Anyone know if surveyor is correct, or are there seperate senders for each gauge, or does one sender drive both fuel gauges?
