Okay I have a dual battery switch and dual batteries, I have had my boat on the trailer for over the past month and have been doing some electrical connections, the batteries are getting a bit low. Can I just connect a battery charger across the negative and positive terminals, negative on one battery, positive on another and charge the batteries back up?
If not what do I have to do?
On another subject I am taking a new West Marine 580 VHF radio back to West Marine as I cannot get the NMEA 0183 connection to work, my Garmin 741xs list their version of connections and the 580 has their version. I cannot get GPS position to the radio, though the radio works, and the NMEA 0183 is set up on the Garmin 741xs. West Marine has no support phone or email for questions, and I am **** tired of playing multiple "What If Questions?" with wiring connections. I have already also paid a technician to try and wire this and he cannot get it to work.
This should be a simple connection but the manufacture's will not use the same language and markings for their NMEA 0183 and I am tired of mucking with the whole affair. One will list wires as port one or two + or - while anther does not. Dose a Garmin Tx connect to the radios Tx? or does the Garmin Tx suppose to connect to the radios Rx? Then which is positive and which is negative? Just pure unadulterated BS. It cost me as much for the tech as the radio alone cost. Grrrr!
