2008 Precedent Replaced Speed Sensor - Problem persists

[tonydutt]

Hello All,

I have read most online postings about my 2008 Club Car Precedent 48V speed problem and can't find a solution.

Problem is cart will only go about half speed on a full charge. Here is what I have done:

1. Replaced the Speed sensor (ADC motor)
2. Tried the speed sensor test - pushed the cart forward and received no beeps from the reverse sensor.
3. Verified batteries are topped off with distilled water.

Here are some questions:
1. The speed sensor I took out had a magnet that was a segmented circle. Basically it had two salient ends 180 degrees apart that arced about 30 degrees or so each. The one I replaced it with was a complete circle. Is this causing the unit to not count the RPMs and see no delta as the magnet rotates?
2. Is there another part of the speed sensing circuitry I should look at? I have seen some posts about spraying WD-40 of the "gas" pedal. Is there a potentiometer that I should inspect there?
3. Is it normal for the unit to drip a white corrosive substance? Thinking of switching to gas because of this.

Thanks many.
