I have the new Thunderheart but I imagine the circuitry is roughly similiar with their older models. I had an LED that was shorting out which tripped the relay and wouldnt allow bike to turn on. Another guy on here had a tach ring shorting out that did the same.
He has the older model tapio I think its more forgiving.
Yep. That is correct. The Thunderheart has a relay for them along with a center tail light.
Thunderheart said the same thing. We believe the switch is good. What is really strange is we have not found anything that burnt up yet. I am leaning to the Voltage Regulator or the Transmission Sensor. We both hd to lay off yesterday. Will renew the search today.
Also disconnected voltage regulator feed to battery. So no grounding short there.
When we could get starter response, she wanted to fire but would not. Unfortunately, we have lost that now. Anyway, just seemed like the coil was trying - thinking it is ok.
You sure you didn't unplug the green starter trigger wire while you were messing with the transmission speed sensor?
Got the starter response back. The second cluster was loose at the ehc. False alarm.
She wants to fire without the voltage regulator connected but just doesn't seem to have enough voltage putting out of the coil to fire.
Eric. Yeah, we caught the green trigger wire. We just got stumped.
If you got a spark plug tester id make sure your truly getting spark on both cylinders. It won't start with only one side firing. Or ground plug to fins
Ah gotcha..so upgraded with that ignition. Either way I would Check the spark manually just to be sure it's really firing on both sides.
As all of this is happening, the ehc does not sweep the speedometer, no lights come on, and there is no evidence of life there. What we are nearly successful at is firing the ignition module in spite of the ehc.
Was just gonna ask if lights worked..
I failed to mention early on, this has the second Thunderheart ignition module that Shannon mentioned earlier forward of the module itself. It resembles the racing ignition module you see on Thunderheart's webpage that is for dual fire. This is what was bypassed by the Crane. So the ehc control module itself merely relays circuits to components.
