Although it is still freezing cold outside during this years winter months, I spent some days in the cold garage to start working on the Pimperado again.
The main problem which keeps me busy at the moment is another defective ECM. It quit working during a cruising tour last summer. Before that it worked like a charm.
ECM issues are plaguing me for a couple of years now. After a long search I found out that the last ECM was shot due to a defective solenoid on the EGR valve, which I replaced last spring. I still do not know what caused the most recent ECM to quit working.

With the help of Barni - an electrician- and the shop manuals wiring diagram we tried to find possible issues in the electrical system, but we could not find any problem. All solenoids seem to be o.k. this time.
Barni will try to repair the last ECM with parts from all the other ECMs which I have lying around in the parts shelves of the garage (see pictures below). I hope he can fix it. This electronic stuff really is a major pain to repair and to diagnose.

Also did some other minor repairs and adjustments on the Pimperado and some conservation work. Looking forward to the next stay in the garage.
