Hi All,
I don't have a berg anymore and don't get on the site much. Back when I had the 02 470 I spent a lot of time trouble shooting the ignition. You guys were a great help and I thought one of you might have some advice for me.
I recently spent some time trouble shooting my TL1000S. It seems pretty clear how to check various components of the charging system. I was able to check the generator for various AC / Resistance values engine on / off etc... I also was able to check the rectifier diodes by looking for the voltage drop between the input and output. THe one part that i don't understand is the regulator. I understand zener diodes in descrete terms and how ICs can manage the same, however my question is more practical.
Why doesn't a modern R/R output ~14.5V DC without a load. The configuration is A/C connectors are plugged into the generator, engine running, output of RR unplugged. Why can't I measure a 14.5V output. Unplugged two different working regulators only show ~ 3.5V DC. If the Battery is connected then I see the Regulator jump to 14.5 V (Battery alone is ~13V).
I was thinking that the load of the VOM wasn't enough to turn it on but not sure.
Thanks,
David
