Grundig Satellit 1400 SL not working - UK Vintage Radio Repair and Restoration Discussion Forum

Hello all

I have a Grundig 1400 SL that was owned by my grandad some years ago. I always remember it working, but the family member that had it before me has tried to use the radio on a brushless generator (not a clean sine wave) now the radio fails to work.
I have around 44 volts between the fuse and power adapter switch.
I have a multi meter and an understanding of electrics, but mainly auto based. Any help in the right direction would be massively appreciated

Many thanks

Please explain which fuse, there are 3, and are we plugged in to 240v AC mains?
I have the circuit diagram and can see no obvious reason why you could have a voltage between any of the fuses and the mains input.
Have you checked all the fuses for continuity?

The power adaptor switch seems to disconnect the internal 9v battery if either a figure 8 mains cable or a 10v to 16v DC supply lead is connected. Are you using the correct lead to operate the switch?
Using a poor sine wave mains source should only affect the mains transformer I would have thought, does it check out?
You need to understand which fuse is for what, do you have the circuit diagram?

I checked the upper fuses for continuity I will check the lower one
I had no voltage between the fuse that is inside the voltage change over switch.
What sort of voltage should I be expecting at these and power supply.
I don't have a circuit diagram I will search and obtain one.
I've have the power adaptor that came with radio and it seems to operate switch

Many thanks Gav
