FNR spade connections

thetoddjohnson

I replaced the FNR switch. The old one had 6 spade connections. I’ve numbered them on the attached photo.

The new FNR switch has a 7th. I just transferred #’s 1-6 to the corresponding location on the new switch.

I'm curious. What is the 7th contact used for?

I believe that is your half speed reverse switch. Look closly to see if one of the 6 wires, "splices" into 2 wires at the end. I think there is a resistor added in 1 of the legs of that 6th wire.

#6 (black) is 1/2 speed reverse ( resistor is seen in vinyl tube)

#7 is NC lug used in 95-97 48v. carts

Thanks all. This cart is a '94 DS. It doesn't seem to have the wire you are talking about. No biggie.

You're right. A 36v. '94 DS doesn't have a wire for that #7 lug (just like my '93)

Your multi-step pot uses that exact 3-lug m/s. So if it suits you, get a 2-lug m/s for the #3 spot (they're around 5 bucks), and keep the 3-lug m/s in the emergency parts box because it will work (universal donor) for any of your cart's micro switches. If you're want a spare m/s, that's the one to have.

ScottyB's diagram indicates wire colors, but not what they do.

I installed the new FNR, and I installed 2 ga cables.

What I'm finding is that reverse works fine. Forward sometimes works, but sometimes I need to jiggle the FNR lever to get forward to work. I checked all the high current cable connections and there doesn't seems to be any problems. Also, when the cart does run none of the cables get hot. I'm assuming that one of the spade connectors (or one of those small guage wires) is going bad.

I know that spades #2 and #5 (on the diagram in my original post) only have to do with the reverse buzzer, so I'm not concerned with those. Which of the remaining four spades could be contributing to my problem?

Just replaced my F/R switch and found contacts did not perfectly line up when rotating from F > R or R > F. I had to "build up" the spots on the F/R switch seats upon rotating. Works now.

I would think jiggle the handle to work effects only the main contact alignment and not the micro switch connectors?
