No Fwd or Rev problem

[408sbfmustang]

If anybody can help I have a Electric Club Cart DS A9701/557440 48volt carb that will not travel fwd or rev.It will jerk a little bit.The soleniod doesn't click closed,no power is going to the coil side of it,Battery voltage is 51 volts,and batteries load test good.Key switch and all fuses are good.If I jump over the soleniod the cart will travel fwd and rev ok.Im thinking the throttle module is bad.
If you can help that would be great.
Thanks

You have either a bad solenoid or a bad OBC. Do a OBC by pass (should be able to find it on this site) and try that first.

The flow of power to turn on solenoid is KEY switch "ON" to F&R micro "in Gear" to V Glide micro "PEDAL DEPREST" to solenoid. I would start by testing the switch, then the micros on back of F&R control and then the micro inside V Glide for correct operation?
When you jumper the solenoid you are bypassing everything in control circuit before AND INCLUDING the solenoids ability to close contacts?

So all micro switches tested good,I went and grounded the yellow wire on the soleniod and melted the jumper and micro on the v-glide.checked the resistor and diode,resistor ok but the diode was continuity both ways,So I have a diode coming and just to make sure what way does it go?

Hope you got a new micro for the Vglide too? The stripe on the diode goes to the positive side of the activation circuit.

if your jumping the soleniod and the cart is working than replace the soleniod....................................

So here is what I have done.Installed new style soleniod with the diode pre installed,installed new micro on v-glide.The cart still doesn't activate the soleniod,so I jumped the new side of the soleniod to the battery now it works.So im guessing the On Board Computer is bad since no neg batt signal to the soleniod.Im I correct

I would agree, sounds like OBC.
