diy conversion of voltage regulator for 65

[Stephen B.]

Has anyone done this themselves?



The hooked an A/C source (vintage American Flyer train transformer) to the connections on the left (F and 2) and measured the DC from the right terminals (3 & 4). The A/C voltage was varied between 7 and 16 volts. All I got was .15 volts on the DC side, which was the same DC voltage produced by the A/C transformer. I noticed that the farthest left connection (F) is the grounded to the case and the heat sink for the power transistor.

I purchased a new, generic electronic regulator for the donor components.

Any ideas as to why I don't have proper level DC voltage? What is the A/C voltage supposed to be from the alternator that's fed into the regulator.

Thanks in advance...

Steve, the alternator supplies DC to the regulator. That's what the six diodes in the alternator do. You need to use a DC power supply in order to test your regulator.

aha! I knew I'd had forgotten a critical fact. I'll try it tonight.

Thanks
