I have a new boat with new 2005 model 115TXRD and a T8PXRD and I've had a couple of strange symptoms that I think are charging related. Both motors have about 15 hours each.
Symptom One:
1. I think there is a voltage problem with getting too much voltage at the fuse box. The problem that I am having is my Fishfinder is telling me it is getting too much voltage (>15.6V) when I am just running the kicker motor and have the key shutoff to the main motor. The kicker is wired into a dual battery setup along with the main motor. There is a battery switch to go between each battery or both. The FF is wired to the fuse box and happens to be double fused, once through its own and once via the fuse box fuse. If I turn on the main motor key, to light up the gauge package and power up the other instruments then the FF does not complain and works fine.
Symptom Two:
2. I blew a 3 AMP fuse for my VHF (which is new, ICOM 302) and is wired to the fuse box. The fuse blew while running at close to WOT (4400PM). The kicker motor was not used in this scenario since I was up and planing with the boat. This sort of indicates a charging issue with the main motor although it could have been an anomaly since it is a bit unlike symptom one where the kicker was used.
The advice of the boat manufacturer that built and installed the motors was to take it to a Yamaha Service dealer to have the voltage regulators checked which seem to make sense but I'm wondering if there is anything else obvious I can check. Since I bought the boat a long ways from where I live I can't go back to them for help so I'll use local service if needed.
