Probably no easy way if you can' get the distributor out. Just pull apart what you have to pull apart.

The Thick Film Module needs to be installed correctly first time or it may fail due to litttle heat transfer to the base heatsink hence the use of the heat sink compond.

You are talking about the T.F.M on the side of the dizzy arn't you?

It's best to get a Bosch module (there's some other brand that fits but isn't as reliable) - the Bosch module comes with a small plastic packet of white heatsink compound (really sticky and foul smelling stuff) that has to be smeared on the back face that presses against the dizzy.

To remove the module, remove the main connector then take out the two screws - the module has three blade connectors that go up into the top housing of the dizzy so once the screws are out slide the module down to finally release it. Installation is reverse of that procedure but do clean off the contact face on the dizzy thoroughly and then use the heatsink compound supplied.

There's also an oval shaped soft gasket sort of thingy to waterproof the part where the module blades push up into the upper housing - so have a care not to lose it and make sure you fit it with the new one.

Hey Barry - another product idea for your lineup would be a "Remote Module Mounting Kit" comprising of a 3 wire loom and a heatsink base mount to enable the module to be fixed maybe on the suspension tower - ie. away from the dizzy/engine heat?.

Look here 1st http://www.therangerstation.com/TFI_Diagnostic.html you can open them up and find that it will be a diode or resistor failure and if you know anything about electonics they can be easily fixed for a few cents.

What happens if you don't use the heatproofing stuff?

I recently swapped the buggered MPI dizzy TFI with my old CFI TFI without using that heatsink stuff. What will this do? It's running fine so far, done about 100km in the heat like that. What are the signs of failure?

By the way, it's pretty easy to change a TFI. Undo the 2 screws in it and slide it down gently, it will come off. Then installation of the new one is a reversal of the removal procedure.
