2003 Thunderheart module red LED
- Thread starter aris
- Start date
Can you re-write that again so we can understand what it is you are asking for?
There is no on and off switch for the lights on the ignition module so don't understand your question. Could you be referring to the Run/Off switch on the handlebar?

The red is an indicator from the cam ignition trigger, while the motor is running it will be solid red. The light will flash while cranking the motor (during starting ). This is a good question, knowing about the Red light will help you troubleshoot why the bike will not start later.

Aris. Here is the link to the trouble shooting PDF files on your Thunder Heart ignition module. Hope this helps. Thunder Heart/Tech Support

When I turn the key the red led light comes on, but then turns off, and the bike just turns over and over, but will not start... NO LED WHEN CRANKING
That means the unit is getting power. RED light is supposed to go on just for a second on the 04 then off but it should blink when cranking.
Check your cam sensor. If you need one, I will include a 3 pin JST plug for you in your order as that is what was used on 04.

CAM POSITION SENSOR PLATE. THIS DOES NOT HAVE A PLUG ON THE END- WIRE MEASURES APPROX 42". This is the cam sensor used on the small silver Thunderheart ignition modules used on most 02-04 bikes. LOOK AT PICTURES CAREFULLY AND LOOK AT YOUR BIKE TO BE SURE OF FITMENT.

Pull off the cover on the nose cone and there is some information on the forum for the testing procedure, although you may not need to test it if it looks melted which has happened over time with the heat from the motors.
Must be cam sensor week....

Might be a dumb question but now that I fixed all the wires, finally getting lights to my ecm just to find out I still cant ride tonight or tomorrow... unless there is a way I can bypass the sensor? Just temporarily! And how much for the partThat means the unit is getting power. RED light is supposed to go on just for a second on the 04 then off but it should blink when cranking.

Can't bypass the cam sensor. That's what sends the signal for timing on the spark. Looks like it got a littled melted by the pics.
The link in my original post to get you a new one.
