how do you rig up a l.e.d. to come on when the engine is over heating?
The second gen does have a threaded boss but that is where the temperature sensor (not over-temp switch!) is installed.... I don't know if second generation bikes have a threaded plug where the thermal switch would go (same housing as first generation). If not, you would have to replace the thermostat housing with one from a first gen....
If you want the LED to illuminate on 'ignition -on' as a 'test' feature simply add a diode to between the overtemp signal and the oil pressure light - then it will come on at ignition (getting ground through the oil pressure switch) & go out when the oil pressure switch is satisfied. The diode will prevent the opposite happening if youget a true overtemp situation (although the overtemp light WILL come on with low oil pressure, but that would be least of your worries!)The warning light doesn't light up on start up, so to test it you pull the wire at the thermostat from the LED and ground it. The LED should light up.
my soldering skills aren't great but if you'd be willing to draw it i'd be willing to try it.For B.a., the OP - An alternative to adding the thermal switch - a fairly simple comparitor circuit could easily be made to tap off the existing temp sensor in the Gen 2 and use it to trigger a high-temp warning LED. If you can solder electrical components on a board, this can be done for under $10 with only a couple of components. (I can draw it for you if you are capable of putting togther)
Not quite - what it means is that the switch closes at 115 as the temp rises, then opens again at 108 as it cools. i.e. there is a hysteresis between close & open temperatures.108C to 115C (227F to 239F) are the check set points for the first generation high temperature warning switch.
That is, it should not close below 108C and it should close at or before 115C.
i may be wrong but i don't think the fan even kicks on until 226*f i'm pretty sure 215 is with in normal operating temps for a second gen. as long as it cools right down there shouldn't be a problem.HELP! I think I'm another paranoid rider. I've read all the posts but I still wanna ask.
Yes. I'm a newbie. 2008 SV650S. It's got 1200 miles on it and I just had it serviced (for my 650 mile service).
My bike is HOT. I've never experienced the amount of heat on my legs or butt when riding until now. The bike rises quickly to 185F. Within 10 mins I'm stuck in morning traffic. Stopped at a light - it rises quickly - within 10 secs or so - to 215F. by then the light has changed and I get going again. It quickly drops to 185 and once on the freeway, it drops to 175F.
Along with just having it serviced, like an idiot, I blew the starter relay fuse jacking around with the taillight plug. I replaced the starter relay fuse and checked the fan fuse. All good. I was thinking it was one of these events that caused the problem but I don't even know if there is one now that I've read all these posts.
Thanks in advance.
Great. Thanks guys. I'm feeling a little better. It's just wild how wide the temp range is.215*F for being stopped at a light sounds about right. That's about the average temperatures I run.
