It's alive! Took the
distributor to some guys this morning. Turns out the coil was shot and the module I had bought was wrong, so they replaced that too. Cost me R900 (South African Rands) so all in all not too painful an experience. Regarding the module (see pics), the circuit board obviously packed up previously so here in SA the guys were doing a mod where they ran wires from where the board would have been to a remote module. The guy that fixed mine said he could change mine back to standard but the chip alone is R800 so it is not really a problem to leave it, as it works fine. One problem is that there are about 5 modules that all look the same so unless you really know what you are looking for it's easy to get the wrong one (as I did) and you generally can't return electrical parts. Two pieces of advice that might be helpful, was told that dodgy plug leads are a
distributor/coil killer, so always keep an eye on them. And be careful that the alternator is not overcharging as that can also wreck the coil and module. Thanks again Russ for your help.
