• There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

HELP! 2008 GS SM5 Starter not turning over despite excellent battery voltage

Yeah, the tech said there's really not a way to reflash. Hope he's mistaken and it's just a procedure they haven't had to do yet. I'd hate to guess at the cost of a new ECU...

I spoke to the tech at the dealer, a good guy with several years experience. He's never encountered a Spyder doing what mine is doing. I'll take it to them next week. He'll contact BRP for advice before proceeding.

Basically my current starting procedure is clear safety message, cycle display to Hr, hold down headlight override and press M switch, release and press starter. VROOOM! Anything less than that and the fuel pump cycles and safety message resets, ad infinitum Once bike has started, it will restart normally till off long enough for safety message to reset, then it's back to goofy mode again.

I'll report back what BRP and the tech find out.

What I would do is ride the crap out of the trike, for an hour or more at least on the freeway, backroads, in stop and start traffic, etc. etc. Maybe this will re-educate the ECU about being a member of Spyder society? Make it relearn. It might cure the problem. It sounds like, while being stored, the ECU might have gotten a spike in the elctrical system..from the battery tender maybe?
 
this probably right off the mark but would the dss for the security key be the cause.somehow timing out after key on.do you have another key to try.
 
SO, I thought I'd give you guys an update on the electronic mystery. I trailered the Spyder to the dealer so the tech could experience the magic for himself without having to wait for the safety message to reset. I rolled the Spyder off the trailer and it started correctly for the first time in 3 weeks. Left the trike with them. For 10 days every time they walked past it , they attempted start-up and it behaved normally. The tried it 50-75 times. Not ONE TIME did it misbehave. The called BRP anyway and asked if their tech dept. had ever encountered this. "NOPE." (I feel SO special!) And they had NO suggestions. Me and the tech hoped it had "healed itself " and I trailered it back home.

First startup attempt(!!!) rolling off the trailer, it did THE DEED again, and has done it every time since I got it back home. I found if I clear the service message, cycle through the display options back to Hr display, it will start every time. If I just clear safety and hit the starter, fuel pump cycles and safety resets. Cycle, rinse, repeat... Demon possession??? :roflblack:
 
Is your place near any high voltage power lines?? Any chance there's some electro-magnetic interference somewhere around your place? Is your Spyder parked next to or near the drinks fridge, fan motor, or possibly anything with an electric motor that cycles on & off? :dontknow:
