Ez go stops working, good batteries and have replaced silinoid

[jenepher1202]

We replaced batteries months ago before problem started. A few weeks ago we starting having problems with speed suddendly dropping then after a few mintues it would pick back up to regular speed. So we replaced the silinoid, it seemed to make the problem go away until yesterday it just stopped working. Here are the things we can confirm that we have tried off other forms.
There is a clicking when you press pedal
The charger does comes on and it seems to be taking charge
The voltage read 5 at B+ and M- and then when pedal was pressed down it dropped to zero
Headlights come on and it makes reverse sound
When we try diagnostic it will make the confirming beep but nothing after that
It is model TXTPDS
Date code D2204
Serial 2152442

Sorry I don't have an answer but this is what I would do. The blind leading the blind

First confirm Battery Pack is healthy.

Then start going through the diagnostics posted as a sticky

also I attached a introduction to PDS wiring.

Then wait for one of the experts to post a good answer.

Good luck, and
