Mr. Bigfoot,
Can you post or send that technical bulletin that shows the simple test for the rectifier/regulator? I sold my 2022 TRS to a friend recently and 6 riding hours after he bought the bike from me, his e-start has stopped working. He has replaced the button, but that didn't solve the problem. The bike has roughly 45 hours on it total, so it's hard to think that a component has failed, but still worth checking.
Thanks
