Re: Diode melting
In Backwards???? Probably. The diode should not even get slightly warm.

Re: Diode melting
Is it the diode or the pre charge resistor connected across the large terminals of the solenoid...

Re: Diode melting
When I had it the other way the cart wouldn’t move acted like it wasn’t getting enough power motor…motor just fluttered. Flipped the diode and it ran great for 7 sec then nothing 🤦🏻*♂️🤦🏻*♂️

Re: Diode melting
Also I have a diode and a resistor on the large terminal on the solenoid. The another diode on where the blue and yellow wires attach too

Re: Diode melting
The resistor across the large terminals can go on either way...The diode across the small terminals of the solenoid must be installed with the stripe side towards the positive side of the small terminal...Don't know why you have a diode across the large terminals..What year and model cart...

Re: Diode melting
In your picture there is a diode on the SMALL terminals where it should be. There should not be a diode on the large terminals - just the precharge resistor.
