Default Re: Stumped on 48 V cart

After running through all the steps on the troubles shooting chart...this is where I fail.

Positive connection at terminal #2.
Now place the black negative lead from the volt meter to terminal #1 and connect the red lead of the volt meter to battery #1 positive connection. Activate the system and again if you are not reading 12/24/ 36/48 volts you have confirmed that battery negative is missing. Again depending on the system the Buggy is using the missing negative will need to be traced to its source. Some systems supply the negative from a controller output or with some Club Cars the computer. Most gas cars use ?frame? ground. Electric cars do not use a frame ?ground?. You can determine this by the use of the correct wiring diagram.

I may try tonight running a jumper from negative small post on solenoid to last battery negative post. If cart works....would this automatically mean a bad OBC ???

To answer your Diode question, read this but basically to pass current through the diode negative on the band side (cathode)

All you need to do to test that solenoid to to put full 48 volts across the coil to energise it, yoU can do this on a bench to hear it clicking.
If it is working then this isn't the problem, time to look elsewhere for your issue.

I was looking at your schematics, Crash said check your micro switches, looks like you have several. The schematic on the second page I sent you is colored easier to follow than the first one. There are several possibilities that is preventing your solenoid from getting signal, the controller is one, but you will need to do some testing and eliminations, it is tedious if your not familiar with the wiring on your cart but is is a good lesson to learn for future repairs etc anyway, break it down and post the questions and what your doing here.

I jumped from small #2 neg post on solenoid to last battery neg post. Solenoid clicked and cart worked. I guess I have a bad obc? Will temporarily jump until I can get a new obc unless you think this could be damaging. Any more tests I can do to make sure obc is bad (and not a connection or similar?).

You can make the wire permanent and use the cart without worries. The obc has failed in it's ability to provide the negative side of the activation circuit. However, this will bypass the charger receptacle safety cut off.
Be aware the cart can be driven off with the charger plugged in if you bypass this obc feature and run the charge cord through the steering wheel before plugging the cart in to prevent accidents.

I would not buy the obc, unless you know that was it. Hold on I'll see If I can get ScottyB to help, he is more familiar with these older carts.

LOL he beat me to it!
