    Hello folks, I am new to this forum and first time Triumph owner. Bought my 2023 Speedmaster with 11k miles on it second hand a few months ago. I have been riding it a decent amount and loving it.

    Background:
    A month ago, it wont start at all. Headlights, taillights, brake and indicators turn on, nothing on the dash/instrument cluster and no engine whirring / clicking. Checked battery was good. Ignitions Fuse 7 was blown, I replaced and it happened again and at that point the dealer identified a short and fixed it.

    When taking delivery from dealer, I noticed, the indicator lights no longer working. During that little test ride, i stopped at a gas station, filled up, turned ignition key to off, then restarted no problem.
    When I brought back to them, they initially thought its a fuse issue, and then said the bike wont cut off ignition even with the Ignition switch off (key in off), nor with the kill switch, nor with stand down.
    This is a problem that I have not faced myself. This problem was first noticed by the dealership when they tried to investigate the indicator light issue.

    Dealer claims to be investigating this ever since (4 weeks now) and still not resolution. The dealer noticed a leaking stator dripping oil to the rectifier and replaced that under warranty. I saw some generic posts (liked below) of this issue on other bikes, and the obvious culprits to check and eliminate seem to be the stuck solenoid, bad ignition switch, short or ground issue at some connectors. The dealer claims it could even be an issue with the ECU??

    Here's the problem I seek advice on:
    • Is this a known / common issue with triumphs? I checked with 2 dealers in my state and no one seems to have heard about this issue before
    • What is the course of action that the dealer tech should follow? that is what things should they have eliminated as causes and in what sequence?
    • I am not getting any details from the technician, just garbage blah from the service desk, and so seeking advice if anyone has brought this up to any dealer/ corporate before
    I am not handy at all with electrical circuit checking (I did the basic battery check and fuse replacement, but removing the panels and accessing all wiring was beyond me).

    Any recommendations / advice is much appreciated.

    @GA Forester Yes a strange one on me. But if i purchased it from a dealer i would be looking for my money back or a replacement bike. Not sure how you laws stand towards goods not fit for purpose.

    Thank you @joe mc donald - Unfortunately, in my state, the lemon law does not apply to products not bought directly from the dealer. The law considers a month's time of lack of usability enough time to file for claim, but it only applies to products bought directly from dealer. Mine was a private party sale.

    Lesson learned for me, in the USA Triumph dealers are few and far between and the service exp is not good (in my late realization).
    Love the bike, but if electrical problems like this keep on creeping up, I will have to sadly cut her loose.

    Dealer tech seems to be working with Triumph corporate and my warranty company, and finally after 1.5 months is getting to checking if the ignition switch assembly is bad. Apparently they have to remove the engine block for it , which means labor cost and they need warranty to sign off.. in short, any electrical problems is a PITA because its tucked deep under or inside behind the motor and they will not work on it unless the warranty company assures covering the labor cost
