Re: Melex 36 Volt Cart only goes at slow speed
Controllers are not serviceable....So hopefully you have a bad pot. Controllers come in a variety of sizes ranging from 275amp to 750amp. $300 to rediculously expensive.
If you don't shop ebay try one of our sponsers, they make this forum possible. They are voltage sensative, 36v or 48v also, so "hopefully you have a bad pot" |
Re: Melex 36 Volt Cart only goes at slow speed
sounds to me that your solenoid is dropping out try changing it out

Re: Melex 36 Volt Cart only goes at slow speed
Have you tested the batteries under a load, or just idle? Your symptoms really scream low voltage. This may be from batteries.. other possibilities are loose wires, weak solenoid, bad controller, and possibly worn brushes in your motor.

Any luck on this problem yet. I have a Melex 412 that has the exact same issue!

Re: Melex 36 Volt Cart only goes at slow speed
There are many issues that can cause low speed. A bad battery, weak connection, or worn out pot box are some of the first checks. I ran into my first Melex today and figured I would share for my first post ever.
My diagnosis......burned down commutator on the motor. Over time the gaps between the comutator get filled with bits of carbon, copper, and trash. The cart I was working on today would move very slowly. Put the wheels up and it would move just fine. Everything else checked out....all batteries good, all cables good, pot box fine..... I pulled the access band from the motor to find the picture below. Take a pick and scrape out all the trash between the gaps in the comutator and see how she does. I was excited to see that my sweat today might be able to help someone. -Cheers http://i1347.photobucket.com/albums/...ps826a5e13.jpg |
