Yamaha OX66 250 Motor 2001
well since my boat is only showing 12.8 volts at 4700 rpm i thought it my be the Batteries or the cables being corroded or the battery switch. So one by one i Changed out the Battery switch, cleaned all the cable ends and got rid of all wing nuts, Bought two brand new Trojan deep cycle batteries and after all that all i see is 12.8 when running. The voltage might sneak up to13.0 after a long run but the minute i use any electronic equipment it drops back down to 12.8. ANY IDEAS?
I did have a new brain put on the boat about a month ago, do you think that might have anything to do with it? Do the charging and brain unit even work together????
The boat voltage shows me 14.2/13.5 for about the first 1/2 hour of running
after i have charged the batteries on land after about that 1/2 hour though i never see 13+ volts again all day. i only run one battery at a time.
also when sitting out on the ocean i can check my volts after sitting on a spot for a hour or so and see the battery voltage at 11.6/11.4 volts. This low voltage is when running very little electronic equipment---- Fish finder, bait pump 7amps, music radio, vhf radio, and Gps unit.
Any help is taken here thanks
