Howmany Voltage Regulator Is Needed

hi

just a question to be sure . in the picture i can see the live wire color is brown . am gessing my stekker live wire is blue . i tested it with ohm and the right pin is color blue , on my stekker

picture from site.

my stekker witsh pin is the live wire ?

hi

testing the voltage regulators . its very sensitive . the white wire on the ezbv4 . positive and negative on the regulator . in goes 8.26 volts and out comes 5.93 volts . so that works . only the servo doesn move .  why ?

It's hard to tell how you have everything wired. You may have a ground issue. Try running a jumper from the black digital pin on the ezb to the neutral in of the dc to dc converter.

Test your servo in a known working system or try a different one. Is the white jumper between the ezb and servo good? No breaks or bad connections?

In your video are you powered from battery or your new converter?  If batteries are they powerful enough to start up the servo?

hi dave

i didn use the big convertor but a smal one . and on batteries x2  1 batt on ezbv4 and one batt on the convertor .

that was the problem the negative on ezb to input convertor . the servo or convertor doesn even get warm ,stays nice cold .

thank you dave

Outstanding Nomad! Nice job. I'm glad we figured this out and you have your servo working now. Keep having fun!

hi dave

soon wirering the first part on the chair . the power .

hi

the power cable is connected and i have 4.94 volts . i wil set it higher at 6 volts later . these are very sensitive regulators .
