Testing voltage limiter on dash

[DocMel]

My fuel, oil, pressure and water temp gauge quit working on my 71 Cuda.   

From another post its said the cause is most likely the voltage limiter.   I would like to test it before I spend $65 on another one

There are 3 blade type posts on the back of the VL:   

Two posts are connected and go the ignition, so it gets 12 volts there, simple.  I do have a confirmed 12v going in here   

Do I test the VL by checking the output voltage at the third post?  Thats how I am doing it now and it reads 0.15volts.  I thought 5.0v was supposed to be the output

Am I testing the  VL correctly?

You probably are testing it correctly, but the 5 volts is pulsed, so depending on your meter, it may not be able to read it correctly.

To be clear, it's the post with the daisy chain wire going to the gauges that should read 5 volts.

Then again, the VL could be dead...

Remember to connect the -12vdc to the case mounting tab. Connect the +12vdc to the dual spade lug connector. The remaining spade lug connection should swing between 12vdc and zero. The average over time is 5vdc, but your meter will never read 5vdc.

it is easier to test with an analog meter
