1986 Corona with EFI mysterious electrical problems

First the battery kept going flat, and so I had that replaced.

Immediately the "generator" light went on and I kept using it until it ran down the (new) battery shortly afterwards.

I have replaced the alternator and now it runs out of puff, like its going to stall (automatic) when I press down the accelerator. It seems like it it won't advance the timing properly. I suspect the transistor block for the electronic ignition.

I've buried a couple of cars that did this ; they would keep burning out electrical components (like battery, alternator, iginition coil, leads, spark plugs, transistor blocks, distributor reluctor, dash dials, fuel sender etc).

I suspect its resistance building in the wiring harness and dropping voltage, driving up the voltage and burning out components. The cars have always been 25+ years old.

I was wondering if anyone else has experienced this and knows what it is and how to fix it ?
