I have an RD5200S AC. Creep/limp speed (<0.5mph) only with no codes. Can anyone tell me what voltage readings I should see at the "U" "V" & "W" motor leads at full travel command. All 3 AC motor leads are pulling 300+ amps at full travel demand. I looked at this though access 1 and also confirmed it with an amp clap direct on each lead.

I have already confirmed all my command inputs (POT1 etc.) are at spec.

I'm leaning toward a failed trac mot but would like a little more info to support my theory.

Thanks!
