Electrical problem/defence Escort BJ 1996

Hello, since I have been helped here several times, I try it again. I have converted a 1992 Escort engine 66kw 1.6l into a 1996 escort. Now I have for some time that problem that he no longer jumps. Bzw. he just went off to me 2 times while driving and not again. The first time he jumped again after 10 minutes. The second time he did not jump again. or only after he was dropped from the towing service the engineh Aube opened the battery bridged and it ran again. (Although the one from the car service had checked the battery and she was ok) Maybe it wasn’t the battery but was just coincidence. And the 3rd time it doesn’t go on for a week. Strange is… 1. The radio goes. 2. The light goes (light) 3. The warning flashing system goes 4. The indicators do NOT go 5. The lighting of the dashboard does NOT work if you turn the key on “ignition”. 6. The fuses I have 7. I also changed the control unit. Is also ok. 8. The part where lights on the steering wheel with cable to the fuse box I also tried another one. 9. The type of road service has measured whether there is electricity arriving and it seemed that on the steering wheel / ignition no electricity arrived or so…. Has jemadn any idea how to proceed here without bringing the to ne Ford workshop… Have someone who knows about cars, but also he doesn’t know any more advice. VIE LEN DANK for your help Greeting Alex
