96 DCS, no buzzer, no solenoid click

[yourflorida]

Hi all, newbie here. Just started fixin up a cart for grandma, not having much luck. I have spent much time reviewing posts here, lots of great info. I hope you can help.

1996 DCS (run/tow switch, padel F/R at knee, only the 10 pin connector on controller).

Nothing happens when key on/forward/pedal down. Started to follow the troubleshooting steps and hit snag several steps into it...

I have ref.volt at solenoid bat side, ref -2.5v at solenoid controller side (only if in TOW, not RUN). Have 36 volt on left small solenoid stud (which has a red and yellow wire - NOT 2 reds like all drawings here and manual says!!). I have a BLUE wire from controller on the other solenoid energizer post.

I can get solenoid to fire if I jump from right post (the one with the BLue) to the B- on top of controller. Fires off when I hit Forward or Reverse - pedal has NO effect.

Manual says "replace small black wire from solenoid to B-", I don't have this wire - only a BLUE to controller pins. (page 52 step




I have tested the micro switches for F/R individually, OHmed out fine. Same with pedal switch. Don't know how to test the "ITC" speed thing yet but that may not be an issue yet. Have tried spare solenoid - no change.

Question: Should I be in Run or Tow during these tests? Sounds like dumb question, but not a SINGLE repair manual mentions this.

Question: Shouldn't the blue wire to the solenoid from controller provide the negative to fire the solenoid? Is this why I get it to fire with temp. jumper to B-?

Question: I found a great PDF slideshow on a post here that goes through wiring tests, complete with red highlighted test point... I get to step 5 and that is as far as I get - but it doesn't tell me what this failure means?!

Question: How do I rule out the "reed switch" in charging harness?

Thanks in advance, sorry for such long first post but I can tell you people are into details.
