I put my ezgo cart on charge but the charger would not start. Checked voltage on battery bank and shows 36 volts but runs like it is almost dead

SOURCE: dead battery for one unit won't charge at all. voltage -0- both radios and charger work fine. where can I get battery? P/N MN-160001 capacity 950mAh

First put the dead laptop battery in a zip lock.
Then put the zip into refrigeratory and keep it in freezer for 14 - 15 hours.
Afer waitinf for a long time, take the dead laptop battery out of refrigeratory .
Using clean and soft cloth to dry the battery and get the battery to room temperature (about 20° - 25°)
In the end fully charging and discharging the battery for 3 - 4 cycles.
Now you would see that your dead battery holding up charge for 1-2 hours.

SOURCE: I have 2004 EZgo electric golf cart. When I plug

Check for a tripped circuit breaker. usally at inline with the positive cale of the battery

SOURCE: My 2000 Yamaha golf cart has 6-4cell 8 volt

Yes to both questions. the charger must sense 41.5 volts to activate the relay inside the charger. Being a repair shop, I have a charger that is rigged to charge even DEAD batteries. I do not recommend this for the novice. A charger set on 12 volts will bring the batteries back up to 8.2-8.6 volts. A cheap trickle charger may not put out enough to charge a battery of this size. Remember that they are used to MAINTAIN a charge. Connect the Voltmeter and watch for voltage rise. If it rises to 8.1 or above, it is charging. Trojan battery company recommends charging at least once a month.

SOURCE: batteries run out of power too quick, what is my problem

The voltage should be above 37 volts if you have 6 volt batteries. This must be measured under load. A simple voltage check is useless. If the batteries are over 6 years old, they are probably in need of replacement.

I have an EZGO powerwise 36V charger, model 28115-GO3 that was installed onboard a cart. I want to use this charger for another cart, but the charger has 3 wires out. Why 3 wires? One is +, the other -. what do I do with the third wire? The wires are red, black and yellow; two odf the wires are 10-12 gauge, the other is around 16 gauge.
