I’ve been having a play with the Gutbrod again today.
I’ve put a new charging light on it which now works. (It comes on with the ignition and goes out when running, but i only have battery voltage at the battery terminals when the engine is running)
I removed the D wire from the dynamo and earthed the DF terminal and i’m getting around 18 volts out of the dynamo, which is all good.
I then found a fuseable link in the regulator had blown which I’ve now rectified. but still no change in voltage when running (only around 11.5 volts)
Is there anything i can do with the voltage regulator to bring it back to life?
I’m pretty confident that its the regulator that’s at fault, or is it time to source a replacement?
cheers
