Also with regards to the 1230, barring a valve issue, noise suppression is important too. Check the VM strips on the upper left hand side of the motherboard, check the varistors and capacitors across the starter coils and open and close relays for breaks in the leads (like hidden inside the inline connector etc.). There are varistors across the valve coils too, although these typically last years. If all seems OK (let's get high tech here), turn out the machine room lights and run the car looking for arcing at any point. The Fault 7, or "Start Failure" error is a punk, just like the infamous "Mode B" (found only on the 1230). Look to see if you have a good ground on the controller. There have been times when every ground point in the controller/starter box still have the paint under the connection point...sand it to metal.
Hope this helps.
