Is my alternator failing?

[Studley]

2015 Trophy SE
New Battery 2 months ago
Battery Terminals cleaned and connections tight and secure
Readings:
Static battery reading  ~ 12.6V to 13.0 before starting.
After a cold start I get 14.6V at idle off battery terminals
After the bike warms up I get ~13.5V at idle off battery terminals
After the bike warms up I get ~13.5-13.7V at 3-4K RPM off battery
After bike warms up, under load with most everything on [heated seat, grips, Aux lights, heated jacket, high beams, audio, radar detector] I get ~13.5 V at 3-4 KRPM

Symptoms:
Valentine One will re-initialize ~ every 3 minutes with the audible warning tones
Clearwater [Darla's] running at 50% [on low beam]will pop / bright flash like they have just illuminated ~every 15-20 minutes.

I believe my alternator is on the way out. I have extended warranty but I am getting the sense my dealer does not want to do the warranty work. His comment was if he saw those #'s on the bike while doing work he would not even mention it to me cause he does not consider it out of an acceptable range. I get the sense that as far as farkle symptoms, he believes I run too much stuff on the bike and does not concern himself with those issues.

Thoughts, ideas suggestions welcome

Thanks in advance

Just had a quick look at the workshop manual, it mentions voltages of 13 to 15V at 2000rpm.

I've just bought a mini volt meter funny enough, I plan on fitting it to the dash area of the bike, to keep an eye on the charging system whilst riding.

Studley,

Have a look at this Topic if you haven't seen it ....

Headlight minor flicker - wiring loom issue?

The "Flicker" was fixed by replacing the Battery cables with new ones !

I'm wondering if this could explain your probllems too ?

Cheers

Hey Coconut, thanks for your thoughts on the issue. Something I had not considered. An excellent thread.

I hate to be a lame ass but, can anyone assist me with the part # for the cables shown in the dwillcox post. I went to the triumph fiche but cannot make out the part / part# for the part shown. I will not be going with the main wiring harness but I think I'll go with the Ockham's razor approach outlined.

Many thanks

Studley

No problem !

The parts diagram isn’t the best, but it appears
to be Part Number T2502504 - “Lead - Earth “
and looks like it is both the Earth Cable,
and the Positive cable from the Alternator
to the Battery via the in line Main Fuseholder !


Cheers

Thanks again Coconut. Since I am off on one last ride this fall before winter this will become part of my to be done list in the Spring. I don't have enough time to mount tires and do the deep dive before I depart. I appreciate the support you provide to me and all the other riders on the forum.

Thanks Again

Hey Coconut and others, thanks again for your continued support. I have not had time to do a deep dive to the ground point by the alternator. Talking with others I understand this is not an issue exclusive to Trophy's or Triumph. FJR's have apparently had a "Ground Spider" issue for some time. I understand some have solved this issue by wiring a secondary ground to the frame.

I am interested in your opinion on this and where do you suggest is an easier location for a second ground cable that is not going to be to an aluminum member?

Thanks

Studley
