06 Vector, not charging need help

[ejofwitsnd]

Spent all last week in Pittsburg NH with my wife's sled down, bummer. We have two identical 06 vector GT's. My wife's sled was slow to start so I changed the battery for a new one. When I put a meter on the battery it read 12.5 VDC. When I started it up with all of the stuff that it powers it gave me a read out of about 11.4 VDC at idle. I cranked it up to around 3000 RPM and it barely made 12 VDC. My buddy and I drove to Errol nh to the Yami dealer he ran off the troubling shooting section for us and tested the resistance of the stator coil and it read .3. He felt that it was close enough to specs. (.22-.26 ohms at 68 degrees F.) It was about 30 degrees out. He felt that it was the rectifier/regulator. I purchased one. (He pulled it out of a brand new sled). When we got back to our place I replaced the original voltage reg. (R/R) with the new one. Thought that I was set to go. I neglected to test it with a meter. Got about 2 miles out and stopped. It did not want to turn over. I disconnected the lights, jumped it and flew back to the cottage that we were staying at. The next day I put the new R/R in my sled and it cranked out 14 VDC at about 3000 RPM's. I then tested the stator coils resistance on my sled to compare it to my wife's. It gave me comparable readings of .3 ohm's. (White-White with the positive in the middle according to the troubling shooting sheet that I had been given.
Put the new R/R back into my wife's. Drove home yesterday and today I pulled the main load relay (suggested by my mechanic buddy) and tested the voltage. It read 11.7 VDC at idle. NOT GOOD. Tomorrow I am going to pull the R/R out of my sled again and put it into my wife's as a last try. (I know it will not work) but if I bring it to the Yami dealer I want to make sure that I know that it is ok. I need some help.

MY analysis is that if both (my wife's and my sled) are within spec.s so her stator (coil) is ok (273.00 for a new one without labor), and I know that the R/R is ok since I swapped it out to my vector and it cranked out more than 14 VDC at about 3000 RPM that something else is may be causing my voltage drain, I think. Before I invest the money in a new coil plus labor are there any suggestions out there what I could do next.

I blew it !!!


I tested my Voltage reg. on my sled (never tested in my wife's up to this point in time) and it cranked out better the 14 VDC at about 1300 RPM's. I then did the unthinkable and pulled it out and put it into my wife's sled. It still did not put out more than 11.7 VDC. I then decided I better put it back into my sled and test it again . It now does not crank out more than 12 VDC at 5000 RPM's. I must have fried it. Now I suspect a short somewhere and have no clue where to look.
Any input would be appreciated.

I am going down to a dealer now to pick their brains before I do any more stupid things. It is beginning to add up.

Even though the battery is new , could it have short ?

Are the batteries fully charged? The sled does not have the power to charge a significantly discharged battery. I would charge them both up, and then measure voltage across each battery. Should be 12.2 VDC.

BTW: Even a new battery has to be fully charged before you install it.

I made sure that the batteries were fully charged. I put them on my battery tender charger until it read out fully charged. I dropped my wifes' sled off yesterday for the tech. to check out and hopefully find the problem. Now I am at there mercy and time schedule.

While there though I did find out that Yamaha is going to replace some idler wheels on both sleds. It seems that they have been having a problem with some delaminating and are taking a proactive stance. They had to run our vin #s to see if they fit under this window and they did. May be worth others checking out also.

Do the wires under the tool box chafe on the chassis like the 03 rx1 did. I had similar troubles with my rx1 and the wires were grounding on the chassis. May not be the problem but something simple to check and rule out if all is good and not grounding. And maybe the wires are run different where they were having troubles with the wires on the rx1 I don't know, but it takes only a few minutes to pop your toolbox out. I looked at the exploded drawing for your sled and I do believe it is the same as the rx1. Good luck, just a thought for you.

bgallant_7@hotmail.com: Glad to see you have time to work the Forums a bit! Life is good. Eh?

For sure. Just throwing things out there and hope it helps someone. Much the same as yourself in my call for help.
