My 2000 Yamaha golf cart has 6-4cell 8 volt batteries. I did not leave the cart plugged in during the winter months. When I attempted to charge yesterday, the charger lights sequenced but stayed on "Incomplete". The charge level in the batteries is approx. 7 volts apiece according to my voltmeter. I understand the voltage level must be at a certain level for the charge to start. Is this correct? Will a 12 volt "trickle charger" bring the level up? Help.

The best solution you'll get from books at www.reliable-store.com

These are books containing info on repair, service, troubleshooting, parts info, assembling dissemble, removal, error/fault codes, wiring diagrams and everything on any vehicle- cars, atv, trucks. forklifts, boats, excavators etc.

Check the starter solenoid, but sounds like the starter is bad. If it is draining the battery when you try to start it, then it is the starter. Check for a bad ground first though. The starte requires a great deal of amperage and a weak ground could be the problem.

Its been a wile but if I remember right it goes from the solenoid under the cart (pass side) to the key switch (the other wire is probably volt meter) then micro switch,green wires from micro switch to controllern. Inspect all spade connections

What I did was to buy a good blue tooth speaker and connect to my cell phone. 3 hrs on the golf course and 10% of the cell battery

Yes you can but the down side is that the total amp hour rating from 3 x 12 volt batteries may be a lot less than the amp hour rating from 6 x 8 volt batteries. This means you will run out of battery power a lot sooner.

You need the voltage output tested with a special tool by the dealer or a trusted repair shop.

Have the batteries tested with a load cell. Just using a volt meter will NOT work. Look at the posts and make sure all the wires have NO corrosion. Trojan, Powertron, etc batteries last about 6 years. Check the water level after charging. IF YOU SEE ANY WHITE ON WHAT SHOULD BE DARK GREY PLATES, THE BATTERIES ARE SHOT...

With the engine running at about half power/speed, put a volt meter across the battery terminals. The meter should read somewhere around 14.5 volts. If it is below 13 volts it is definitely not charging. Consider that the battery, unless new, could also be failing.

Your batteries have died. The reason it will barely move in reverse is that current is being supplied to the motor is a direction that it spends very little time using. There is a slight change in the armature over time, and reverse tends to work better over time. Check the voltage when under load. (run jumper wires from the + and - of the battery bank. If it is a 36 volt cart and the voltage drops to below 36 volts, you do not have enoug current to run the cart. Plug in the charger and watch the ampmeter. If it goes up to about 20 amps, then it is charging. It should take a good charge after 10 hours. If the cart charges and only runs a short distance, the batteries need replacing.
