Bought a house and in the garage is an ezgo

plezgo

Just closed on a house and walked into the garage and found an e-z-go golf cart with the battery charger. After checking and filling all the batteries I plugged in the charger and nothing, hit the batteries with a jump box,with the charge plugged in, and it started to hmmm. Guessing the charger has to have a back charge to kick on. After charging for 48 hours battery meter show full, but when I step on the pedal it starts to take off but goes nowhere, it did move an inch once but wont move now. After doing some looking I believe I have a 1995 e-z-go Textron. I know nothing about golf cart, but I do have a welding mach, and a 2000 jeep wrangler sitting on 33s along with a 2003 ford excursion sitting on 37s I know they have nothing to do with golf carts but I do all my own work so I am mechanically capable. Any help would be great. Thanks

Welcome, this is a great group of people!!
read the stickies up top there and if not found ask


also dont feel bad, a neighbor up the street bought their home, in january
they have some big oaks and sweetgum trees in the back yard and they were not gardners or anything and one day a man knocked on their door to open up the pool- THEY DID NOT KNOW THEY HAD A POOL
Swear to God
I sure thought it would be listed on some form when buying the home

their neighbors are coming up with stories about stuff they do
I do not believe they owned a car until they moved to st. Louis and the neighbor \said DO NOT EVER RIDE WITH HER AND NEVER NEVER NEVER ride
ride with him

Unplug the charger

First thing is to check the battery pack voltage with a voltage meter. If you don't have one you may as well get one. Just a cheep $10 one is usually fine. Next check to see if you can find a date on the batteries. May be stamped into the post. I'd guess you need new batteries but even so that's a nice little "free" addition to the house buy. I found an old Montessa 250 MX bike behind the shop when I bought my house.

Most likely the batteries have sulfated and ready for boat anchors.

Does this sound familiar?

You plug in the charger and cycles very quickly indicating the batteries are charged. Check voltage and it measures OK. Then you put a load on the batteries and the voltage collapses and plummets toward ZERO?

That is a classic symptom of a Sulfated Battery and is the root cause of 90% of battery failures. Remaining 10% corroded plates.

When a lead acid battery is less than 100% charged up lead sulfate crystals begin to for. The deeper you discharge the battery crystal formation accelerates and accumulates. Once the batteries are discharged below 50%, or if the batteries are allowed to set less than 100% SOC the once soft lead sulfate crystals begin to collect on the negative battery plates and harden. Once hardened the damage is permanent and accumulative. The result electrically is the battery internal resistance begins to rise and you loose capacity.

However we have a lot of control of how fast the crystals build up and harden. We cannot stop it as all batteries, well at least 90% of them die from Sulfation. But we can delay it with proper care and maintenance.

1. We recharge after every use like clock work. Normal charging dissolves most of the soft crystals back into the electrolyte and is part of the normal chemical reaction of charging/discharging.

2. Never ever discharge more than 50%. Crystal formation explodes and starts hardening. If left below 50%, the battery self discharges even more and you get a runaway effect. Battery keeps self discharging and crystals harden. Then we coe along, charge it up, and NOTHING. Its dead and aint coming back.

3. Measure Specific Gravity and check water once a month. Add distilled water when needed, and Equalize Charge the batteries when specific gravity gets out of tolerance. EQ is a controlled over charge which will help knock some crystals off the plates and equalize the charge in each cell.

I would suggest getting a automotive battery charger, and trying to bring the batteries up some (not necessary to remove all the wires). Get a volt meter and post the individual battery voltages here.

What I read ..... somebody abandoned a golf cart in a house for sale. the batteries were so discharged the cart would not move. Charger ran for 48 hours. (8 is normal) The cart moved a little and quit.

If these are not dead batteries I'll eat my ball cap


Careful trying to run on weak batteries. Low voltage causes amperage spikes which will heat up the controller and kill a DCS control in a moment or two.
I suspect you have a series Medalist?
Check one chart below to determine drive system.
Check your batter pack voltage against the other chart to determine their state.

First let me say thanks guys. Second the plates was white when I added water, figure the batteries are shot, once deepcycles go dry they are all but shot. Here what I dont what to get into replace all the batteries and find something else major is wrong. I was hoping that I could get enough life out of the batteries to tell this. The story with the house is he left 8 years ago and filed for a divorce and left the golf cart and she wont let him have. The most up to date tourney card in the cart is 2005. Going to say its been sitting every since.
I put a DVM on the batteries and it is reading 22volts does seem to change.

Can I put my deep cycle 12 volt from my camper and the 2 12 volt batteries that I run in the excursion on it to make sure it worth the 600 beans for batteries?

Have at it. It's a valid move to verify the cart, just don't expect to get any range or performance out of it.

What did he shoot?
