Can you test SH775?

[1948man]

The stator papers specify that the test for the R/R works on shunt type R/R's. Is there a test for the series type R/R's?

If you got a AC clamp amp meter to measure current in any stator leg ,you can see the sh-775 controling the current .

Thanks, I don't have one (clamp meter) but I think I'm understanding there is no simple test of a non-installed series stator like there is for the shunt-types.

If you take a no load output voltage from the SH775 will you get the 14.5V with a DMM or does it need to be under load to output that?

Don't run any R/R without a battery connected.

I have not tried it, but I would think that you can check the rectifier section the same as with the shunt-type R/R.

To test the regulator part, you have to have current flowing through either one.

Thanks, will try the test.

The SCRs won't allow forward current flow till their gates are triggered "on" by their control circuitry - I'd leave them be and do amp test if I got curious.

OK, I was not aware of the components inside. Kind of assumed they might be diodes like previous R/Rs.

Okay, thanks.
