Once you get it working on the bench, proceed by installing just ONE component at a time on the engine, and re-test. If it still works, install the next component and re-test. Repeat until the entire system is installed. If it quits working after you installed a particular component, then you know you have a connection problem with that component.
See the photos below for how I bench test the TIM6 with the ATV coil.
- The tab on the coil connects to "Coil +" and the coil frame is connected to "Coil -" on the TIM6 module.
- Cut the end of the coil's spark plug cable so that about 1/8" of the copper wire is exposed. Secure the spark plug wire to the coil frame so that the exposed wire is 1/16" to 1/8" from the coil frame. No more, no less or you can damage the coil. The spark will jump here.
- Connect your 6v battery to "6 volt+" and "6 volt -" on the module.
- Using a bent paper clip, quickly touch and release the "points" terminals on the connection block several times. This simulates a "points" system. Each time you make a connection you should see the LED light up, and when you release a spark will jump across the gap of the spark plug wire and the coil frame.
- Switch off power, or disconnect "6 volt +" on the module
- Hook up the Hall sensor to the switch block following the TIM6 Instructions, or as shown in the photo below using our Hall wire.
- Reconnect power.
- Spark Plug
- Points or Hall/Magnet
- IMPORTANT! At this point, also ground the TIM6 from the "Engine Ground" or "6 volts -" on the board terminal block to the engine frame before testing. This is to provide a path for the coil's high voltage to ground in case the Hall sensor or wiring is too close to the engine. Failure to do so may cause the spark to jump from the legs of the Hall sensor, or the Hall sensor itself to the engine frame and blow the Hall or a board transistor.
