Regulator testing on the bench

[RHB]

Does anybody have any experience testing a regulator on the bench. What sort of input (variac set to 20V?) could I use to simulate the stator coil?

You might be able to use a scope on a working system to see the sine and try to duplicate it, put me on the list for the second one.

Might is the key word here, because there are different types (some are ACin/ACout, some are ACin/DCout). You may have to switch back-and to with your meter from the two, but the idea of using a variac on the input to simulate a stator sure souinds like a plan. But use a circuit breaker inline on the input of the reg,just in case the regulator is chorted...Or you might end-up replacing the reg and the variac. <br />I got a variac, and will try that myself to troubleshoot one next time.Thanks for the brillant tip <br />Rectifiers can be checked like a set of 4 diodes.

I'm heading to the boat today with a scope. I'll post back if I can come up with some usefull info.
