Melex dead in the water.

[QUOTE=Kal;1009796]I'm running out of them. Try messaging a guy on here by the name of JohnnieB.
I just messaged JohnnieB, thanks, Tony

Let us know how it goes.

Tony PM'd me and about all I know about Melex carts is that they are an EZGO clone made in Poland.

I found a couple wiring diagrams for a model 212, if that is what it is.

Does it match either of the first two attachments?
If so, the high current circuit more or less matches the high current circuit on the third attachment.

Granted the pack voltage is mighty low, but it at least ought to make it twitch a bit, especially if the rear wheels are off the ground.

If you have the negative lead of your DVM connected to the main negative terminal on the battery pack and are getting B+ (Battery pack voltage) on A1&A2, the problem is between those two points and there really isn't much between them. Check the cables, contacts and connections highlighted in purple on the third attachment.

Hope this helps.

First off I'd like to thank everyone who held my hand during this learning process, I'm happy to say the Melex is alive and well. After reading up on the 12volt motor test I followed the instructions and found that my 36v motor was functioning. I then set out to find the reason it wasn't responding to throttle commands. Disconnected A2 from the motor and with the key on, checked both A1 & A2 for activity, A1 was hot in forward, not reverse, A2 was dead both ways. Removed the forward/reverse switch and found a melted contact point, I figured that it was in that condition due to a high resistance somewhere in the circuit. I then removed the resistor pack and found that one of the four leads was all but vaporized. I did a little cleanup magic to the copper contact and replaced all resistor leads. Reinstalled all motor cables and took her a maiden spin. Still have some tinkering to do but she is moving under her own power.

Glad to hear it Tony.
