Depends if it's failed when you test it.
You need to check output from dizzy when rotating and if the coils not being switched it will be the amp, but the symptoms you describe are classic amp failure!

Just had a quick breeze through this thread. Would have to agree, ignition amplifier does sound favourite. It might also be worthwhile making sure the pick up air gap in the dizzy is correct.

Another thing to check is that the ignition amp is getting power. Do a search, I have posted a couple of times on ignition checks. Hope that helps ya.

ok just got my haynes manual back, had a look and i do have a new amplifier it came already on the distributor ran a wire from battery teminal to coil and no sparks. trying to get hold of something that tells me how many volts are going through, really at a loss now

I would say that its a dizzy problem as long as your feed to the coil is ok then the only real thing that controls the spark is the dizzy. have you put a test light on the cable that runs from the dizzy to the coil? tap into that cable and stay and start it. get someone to see if the test light flashed on and off. if it does then the dizzy is ok. if it does not then there is a problem at the dizzy end.

what engine we talking about anyway? is it a 3.5 EFI flapper by any chance?

yep its 3.5 efi

disco1 is a 3.5 hotwire injection check amp but if you had a new dissy it should have a new amp? or is it a second hand unit or a lucas copy from eblag? if it was a new dissy with your old amp and now new grease on the amp to dissy body then that will cause the amp to fry go back to the garge that did it
