OK. To start I've looked all over the forum and have found nothing similar to my problem. My 225 was bought from a used motor dealer. They did the install. All seemed great. Brought the boat home and took it out and noticed the tech was not working. I checked online to see what a tipical cause would be and found it may be the charging system. Checked the voltage with the motor running and had a little over 12V. The same as if the motor wasn't running. Took it back to the repair shop to have them check the charging system and the tach that worked priot to the install. They called me and said the motor is charging fine and that all the warrenty is good for is to the motor wiring harness connector. Anything in the boat would be extra. They said they hooked up their remote box (Ignition switch, tach, and batt volt gauge) to the motor and it was fine. I still havent got more than 12.2V at the batts or the starter selinoid where the regulator hooks up at any rpm. I took it back again and they showed it running hooked up to the box and it was charging by their gauge. I still have 12.2V I know this is long winded and such. Is there something in the wiring of the boat (ignition switch etc) that would make the charging system not work?
