Did you have the original battery tested before the swap? Just saying that sometimes, as has been noted, it's connection issues. Replacing the battery can be a scorched earth way of checking those connections.
Thread hijack alert.
Riders may have some reservations about water all up in their rides but motorcycles are engineered and built to operate in wet.
Choosing to not use hose water has merit from a cosmetic perspective, water spots, calcium rings and whatnot. Hitting baby square on the metal flake with a 65 psi stream of water may be a source of scrotal retraction after you threw a pile of thousand dollar bills at Victory but both the paint, the electronics and all the other geegaws were designed to take it. I don't use the high pressure nozzle either but the bike is prepared to.
If putting a hose to your motorcycle results in it not operating, you have an issue that needs resolving since water from a hose in your driveway is not any more or less wet than rain on the superslab at 75 mph, a much less convenient time to find out you are dead in the water so to speak.
I haven't yet (brought the new bike to Colorado in October) but will next spring flood my controls, wiring and the basic machine under a constant flow of hose water. One bit at a time, then hit the button. Does she fire up? Does she run constant? Any gremlins in lighting or accessories? OK, dry it off and hose down the next bit. Good? Next. Rinse and repeat. You get an education that could be the dif between a wet ass on a long ride and the red ass sitting in a downpour waiting for the hook.
In 2012 my red bike was new. It's not new now.
It's still a Cross Country Tour, but the tour part is put away so for the most part it's a Cross Country.
“Give a man a fire and he's warm for a day, but set fire to him and he's warm for the rest of his life.”
Terry Pratchett wrote that.
"I'm not from here but people tell me it's not like it used to be.
They say I should have been here
back about ten years
before it got ruined by folks like me."
James McMurtry sings that.
