Here are the measurements I made this morning.


PCZ Plug
White wire = +36.91. (VOM negative lead on battery negative. VOM positive lead on white wire.))
Brown wire = -36.91 (VOM negative lead on battery positive. VOM positive lead on brown wire.) (-.007 if VOM negative lead on battery negative and positive lead on brown wire.)

TB11 screw measurements with key on, operator in seat and accelerator in creep speed except for No.1 screw which was measured in both creep and full throttle mode. Battery voltage= 36.89
#1 Screw Wire disconnected : creep mode 0.613, full accelerator mode 0.008. (Not the near expected 8 volts)
#1 Screw Wire connected 0.412
#2 36.26
#3 36.26
#4 36.33
#5 36.64 (lever in forward)
#6 36.67 (lever in reverse)

I went through the Crown 35SSCT-S trouble shooting diagrams. Based on that and the measurements shown above, I believe the problem is the control card. You mentioned the replacement card had to be programmed for my particular unit. Do I need to contact a Crown Dealer for this service?

Thanks again for your help.
