Resistor/Diode on solenoid overheating

That is when I discovered the resistor/diode wire was blown and replaced it, only to have it blow again immediately. Any idea's what will cause that so I don't keep blowing them?

Hello Susie, welcome to BGW. There is a big difference between a resistor and a diode on these carts. This thread is 7 years old, it would be best to start a new thread with photos if possible and people can help you.

You keep saying Resistor/Diode....The diode must be wired in reverse across the two small connections on the solenoid coil...if it isn't it will blow immediately..as it will short out the coil...the diode is there to discharge the induced voltage that happens when the solenoid is switched off...high voltage /low current or spike...the induced voltage comes from the collapsing magnetic field when the solenoid is switched off...the polarity of this induced voltage is in reverse from the original voltage that was on the coil to turn it on...so the neg lead of the diode goes to the small positive terminal on the solenoid
