Well the new electronic regulator seems to have restored charge to the battery! Easy to fit & uses my old cover, so looks right. I took the opportunity to restore the fuses to more realistic levels (NOT 50 amps on everything!)
I'll give it a good run next week to see if my coil overheating/condenser change has also worked. Meanwhile I have done the old Rally trick of having the other coil all wired up ready to swap over....
The fuel reserve changeover wiring has been located and works, so that will also be fitted …fingers crossed the expense will be worth it !

At last the reserve fuel changeover is in , fitted and working
Amazing how awkward it was for such a relatively simple job! Even the four mounting screws fought back!
But it clicks over and changes… on the reserve setting quite a bit of crud ended up in the pre carb filter… better look at the one on the pump…
Found that the o/s tank mounting bolts had loosened a bit from when the tank came out a couple of years ago, despite self locking nuts, the mounting pads I think had compressed a bit. Better look at the other side!

From what you said, I wondered if you had the gauze in place round the pick up pipe ends ? I've found that if it's missing the pipes can block long before it reaches filters further down the line. The surface area of the original gauze means that enough mesh should remain clear to keep the petrol flowing.
I don't mean that to sound as if the tank is absolutely full of debris but sometimes filling a tank full that has maybe not been full for 20 years or so dislodges bits from the top. Of course, removing the tank is the only way to really clean them out but life is short and that can be a job left to "another time".
I had this problem with the 38 14 but on a test run of 13 miles this morning it performed perfectly and I had a thoroughly enjoyable time out in the sunshine. It has taken a couple of years to reach this reasonably happy place!

The pick-up pipes/solenoid unit I have replaced only had one pipe fitted! My replacement has good wire mesh basket
You are ,of course, right about rubbish sloshing about,but I had this tank off to clean &seal it before w went to Germany a couple of years ago,
All I have to do now is put some miles on it to make sure the new electronic regulator is doing its job and that the coil no longer overheats because the condenser was faulty!
