Hello Ron
I walked away like you said I left it sit for a while. I had other things to take care of. Yesterday I spent all day reading the schematic and tracing wires.
I started at the frog. The first thing I did was check the cancel coils with my ohm meter. One was 26.4 and other 25.7 I thought I had the meter set wrong so I checked the setting and tried the Trip solenoid it was 6.5 I un-soldered the leads to the cancel solenoids and checked them again one was at 26.4 the other 25.7 I thought these were to be 3.4 to 3.6? Are the coils shot?
Next I traced the five wires from the frog to the front of the Mech. I isolated the switches by putting a piece of card stock in between the contacts. I made sure each wire was where it supposed to be. I then traced the wire on the other side of the switch to where it was supposed to go. Now here is where I run into discrepancies between my schematic and what I have. I traced the wires from the CP/CC plug The number 2 pin on the Carriage power and control circuit is 25V it goes to the number 2 lug on the T.S. 2 strip and from there it goes to the trip solenoid and the center of the LC/RC switch on the reversing switch.
However my number 2 pin goes to Lug #4 on the TS2 strip. Pin #3 should go to lug #4 on the strip. But mine goes to lug #2 I believe the two wires need to be switched at the plug?
This brings me to the TS2 strip it's self. I thought the strip was mounted up side down but it doesn't add up
Counting from the bottom there are 5 lugs as in the schematic. I have included a picture of mine I know it is hard to see from a picture but I had to try. I am going to list the lugs from bottom to top and what is soldered to each.
Lug #1 & #2 are soldered together there is a jumper between the two (according to schematic it shouldn't)
(Clamp arm switch, Pin #3 CP/CC plug, Cam Switch V)
Lug #3 Pin #4 CP/CC plug, Negative side of carriage light, positive side of selection indication light.
Lug #4 Trip coil red wire, pin # 2 CP/CC plug, Center post of LC/RC on reversing switch.
Lug #5 Trip coil white wire, Clutch switch W, Switch V on cam switch.
I want to switch the #2 and #3 wires on the CP/CC socket but after tracing the wires from the TS2 strip
I needed your opinion.
Thank you for your reply
