new member searcing forum diagrams/manuals for EZGO man code F1186

[twoskinsoneman]

I have new been a cart buff but I was recently given an electricial EZ-GO cart that does not work. It is a very basic resistor style 36v system. I have reviewed a lot of the post looking for a diagram and can't find one.
It has six 6v bats in series, a F-N-R reverse switch, acc wiper system with five pads. Four of the pads lead to a resistor coil pack. The coil pack sits in the middle of the bat bay parallel with the cart. The 2HP motor sit perpendicular to the cart.
I'll post pics of MON as I am on dial-up out here in the sticks.

If some one has electrical diagrams or service manual I would be grateful.

Sounds like an 86 model resistor cart. 86 was a year that EZGO made some minor changes. Mostly in rear end and brakes.

Here is factory wiring for that year model.





to the addiction.

You rock tastee jams pggroves, thank you.

Question. How does the solenoid see ground? It looks like the ground wire connects to the (A) terminal which connects the motor...does it see ground through the motor stator in the one direction and through the resistors, armature AND stator in the other direction?

Thanks again!

[twoskinsoneman]

whoop. I guess it goes through just the stator in either direction.

Sorry these pics are so bad. I'm trying to hold my camera up in the corner of the room to get as far as possible from the cart. I didn't think about pics until I had it in my tiny shop and on jack stands.







How about that corrosion!

I almost fainted! You got your work cut out for you.

What do you mean "How does the solenoid see ground?

A and B is your main power. It "makes" the main positive connection. C and D are your control circuit wires. They control the activation coil. One wire will be positive and the other negative. If your not familiar with the system you should study the diagram till you do.

Ok ground is the wrong term. I see that the coil sees positive voltage on the C terminal but the other wire on the coil connects to terminal A. I AM studying the diagram. I seems like the coil has to see negative voltage THROUGH the motor. If this isn't accurate please tell me. Is seems an odd way to do it to me.

I'll simplify it as best I can.
Power goes to the A terminal.
The C teminal is the negative of the activation coil. It only looks like it runs through the motor but it doesn't
The D terminal is the positive terminal of the activation coil. It's always hot.
When C gets is negative signal the coil energizes and sends power to B and the rest of the system.

Okay. I guess I'll take your word for it. You say "When C gets is negative signal the coil energizes..." which is clear. But you don' say how it sees negative voltage.

It seems like the Reverse warning and the solenoid coil are both getting the negative voltage through "A" on the F-N-R switch. What provides that negative voltage to that terminal on the F-N-R switch?
