Mcquay PEH 076 Starter problem

The 1mcr and 2mcr are not getting energizied In the starter

Im getting 80 vac on wire # 5 and relay coils on start up

I upgraded safety relay to the Mp3000

When the chiller trips on starter fault

The #5 and 5a have 5vac to ground

The second chiller has nothing to ground?

I m getting some feed back from somewhere

And cant find source yet

Ive checked all my wiring, relays , timer and everything in between. A real head scratcher. Im wondering if the Lead lag is the cause. Any suggestions
