The magic button stopped working...2012 TXC250. Lots of mud, lots of pressure washing over the past year...
Problem was intermittent, hour to hour. I figured electrical, which I don't like!
Rundown checklist...
- All other elec. stuff worked
- Battery had good power
- Direct jump to starter got a response
So I figured it was the button assembly itself... When I took this apart it was somewhat clean inside. Very simple setup…
With a volt/ohm meter in hand to check continuity of the wires, I started at the button.
Button passed the test. Took off the tank and followed the lead to the appropriately colored wires into a plug. Button still passed the test at this location. (On this model the leads were easy to follow, I think a blue and a brown w/black stripe.) The corresponding wire across from the blue in the connector was green and there was the same green at the relay...A quick test said it was the same wire... That's good because there's no way to physically follow anymore...at this point they jump into the 'BIG' harness!
The relay is near the battery and has the positive from the battery and a large lead heading to the starter terminal.
I checked the button at this plug using the green wire and the battery ground...still good. Went thru all fuses...tested with meter...all good. At this point I was thinking bad relay.
Without the tank connections I don't think the starter button will actually work, but knowing I had good wiring back to the relay I decided to take a step back, get another beer and figured I'd clean up under the tank, clean and re-gel all under-tank connections and put the tank back on.
After doing all that, I re-tested the green wire at the relay, still good. I cleaned up the connector at the relay, re-gelled this and after connection…the magic button worked again!
So, back to the thread title… All the electrical connectors; (which there are no two alike) should be maintained just like other stuff.
When the bike was new one of the first things I did was load the connectors up with dielectric gel... but you should have seen how nasty some were inside…
Time consuming, but cheap…my garage heater worked and the beer was cold!
Just trying to help the next guy...
