Wired it up as per picture and fuse blown.

That rather implies that there is a fault with the Thorpark itself. Any chance you could post some pictures of your installation?

Mine is fused at 3A. The positive connection goes to the common ground on the frame and the negative connection goes via a switch and fuse directly to the battery negative terminal.

That suggests either a total failure of the Thorspark unit, or a short to ground somewhere within the installation.  A quick search turned up this thread, worth checking?

I had a quick look before i went to work and it looks like the torspark plate is touching the advance retard puller.

the installation instructions I had stated that the aluminium heat sink may foul on the mushroom on the end of the advance cable causing a short. In this case file away the aluminium plate to create a clearance.

I tried to post the instructions but the scan I have is too big. Let me have your email and I'll send it to you. There was also something about not getting the wiring reversed as it can blow the trigger unit.

Cheers
Pete
