Getting closer, a few things to tidy up, should be able to finish it Sunday night, thanks for the help

Cool, I'm here all weekend if you have any questions

Finally got to finishing it up, here are a few pictures, I really appreciate the help, just need to tidy a few things up

I think I see one mistake- right contactor, top row, metal jumper between 1 and R/L1- should not be one there

 

[Wiscomx78]

Your right, got it taken care off

 

[markba633csi]

I think it might be ready to test- try it first without the motor and see if anything blows
You should hear one each contactor clack for F and R
If that checks then hook up motor:
U & V to 1 & 4
M5 to 8

Just tried it, nothing sounds like it is making contact, wired motor and it doesn’t spin, I’m going to triple check everything and see what I have

 

[markba633csi]

OK- I'll take a look also. No contactor action means no power to coils- I would check for 120v power at the transformer
output lower terminals

I don't see anything- maybe a bad crimp connection?

 

[Wiscomx78]

I have 48.3 volts on x1 of transformer and 8.5 on x3 of transformer

 

[markba633csi]

You need to measure between x1 to x3 with meter on ac volts
I suspect fuse might have blown
