YankeeRedfisher Posted June 30, 2017 Report Share Posted June 30, 2017 Two batteries, Guess battery switch, 1 engine. Both batteries read 12.3 vdc with a meter. When Guess switch is in #2 and I turn the key----it peggs out in the wrong direction ZERO. When the switch is in the # 1 position, motor stars everything fine. Battery charger on board no bad lights. What is wrong. Is this showing a short when # 2 is used. No changes in wiring or anything. Ran fine last year. Link to comment Share on other sites More sharing options...
SCFD rtrd. Posted June 30, 2017 Report Share Posted June 30, 2017 What is pegging out? Do you have a volt meter on the dash? Link to comment Share on other sites More sharing options...
YankeeRedfisher Posted June 30, 2017 Author Report Share Posted June 30, 2017 Yes, it's more like colors green being batteries are charged. It droo\ps down hard similar to when a meter peggs. Link to comment Share on other sites More sharing options...
SCFD rtrd. Posted July 1, 2017 Report Share Posted July 1, 2017 My best guess is a loose or corroded connection on the battery switch. So are you saying that you can't you start the motor on #2? Link to comment Share on other sites More sharing options...
Bamaskeet Posted July 1, 2017 Report Share Posted July 1, 2017 It sounds like a bad switch or cable. I had to replace my battery switch this spring, unfortunately, they don't last forever. Link to comment Share on other sites More sharing options...
YankeeRedfisher Posted July 1, 2017 Author Report Share Posted July 1, 2017 Sorry about the poor description. This is not my RF18 but my Graywhite Seafarer. When I put the battery switch in the #2 position (which is normal batt start pos.) the engine barely tried to turn over. I thought bad battery. When I switched it to #1 position, the engine turned right over and ran fine.(first start up this year). I noticed that when I turned on the ignition with the batt switch in #2 position the needle pegged downward hard (opposite from what it should do which is ascending color bars of red, yellow and green showing battery condition). I suspected a dead battery but the on board charger (2 bank PRO Mariner ) did not indicate a battery fault. I put a meter on BOTH batteries and they tested the same at 12.3V. I'm thinking I have a short on #2 side of the Guess battery switch. Will open it up today to check. I also observed quite a few mud wasps coming out of that compartment;maybe they got in and shorted it out. THANKS for your replies and advice I've been on this forum for many years and find it very helfull. Sure do miss HOBO Link to comment Share on other sites More sharing options...
polliwog Posted July 1, 2017 Report Share Posted July 1, 2017 Sounds like you have found the issue, wasps can screw things up when they make their nests. You want them out anyway to be sure. Link to comment Share on other sites More sharing options...
YankeeRedfisher Posted July 1, 2017 Author Report Share Posted July 1, 2017 Problem Fixed. Even though the #2 Bat read 14.3 vdc it tested as failed on the machine at Auto Zone. My records indicate it was replace last in 2010. Pretty good for an expensive Blue Top. $ 264.00 with tax. Problem was simpler fix then I thought .
