05 Precedent Just Stopped Moving

[mlanierjr]

I was driving along and it just quit. batters fully charged at 50.3V. Reverse buzzer beeps if put into reverse but it does not go. Forward it does not go. The voltage does drop from 50.3V to 50V and the usual "click", I suppose from a relay is heard. Any clues where to start looking?

Thanks for the help.

Is the click coming from beneath the floorboard (MCOR MS) or behind the seat (solenoid)?

Also check the motor wires for damage or broken/burned ends.

I know the regular floor board, but not sure about under the seat. Will check tonight when I get off work.

Nothing obvious. When I get it back to the garage tonight I do some checking. It was just to late to start last night I've learned a lot of the people here can do a great diagnosis from symptoms alone.

Both are clicking . Time to get the jacks out I suppose.

I would test the motor next to rule it out...Put in tow..Remove pack neg...Disconnect the 4 cables from the motor and mark them...Double wrench the studs when removing the cables...Put your meter on continuity...

A1 to A2..beep

F1 to F2..beep

A1 to F1..no beep

A1 to motor body..no beep

F1 to motor body..no beep

Yes it could very well be your motor....However take some advice and verify all "Inputs" are present at the controller. Check the simple items first, The MCOR throttle input has a history of going out way before you lose a motor. As i understand you have solenoid activation...so verify that the pack voltage is at the discharge post of the solenoid.

Sorry to take so long responding, I thought when you created a thread you were automatically subscribed.

Exactly the information I needed. Thanks! Now if it warm up out of the 20s and 30's I start working on it.
