|  Resistor On 48V Solenoid-Necessary? On my 48V cart's solenoid, there are 2 small resistors...1 large one going from the 2 large posts, and a smaller one going across the 2 smaller posts. They got VERY hot last summer and the cart hasn't been running since-my question is can these 'blow' and therefore cripple your cart? Where can I get the exact replacement for these? Thanks! Doc ps...cart is an '00 48V Carryall. |

| Re: Resistor On 48V Solenoid-Necessary? They are a diode and resistor the diode (Small) can fry and short out the activation circuit. The resistor is a protective device to prevent fly back voltage from reaching the controller use Exact replacements when possible. |

| Re: Resistor On 48V Solenoid-Necessary? PS: just so you know the Diode can only be connected in one direction (pay attention to the silver ring on 1 end) the resistor can go either way ! |

| Re: Resistor On 48V Solenoid-Necessary? As I understnd it, the diode is for coil suppression to protect the microswitch that actuates it , and the resistor (250 ohm/5w) is to precharge the capacitors in the controllers internal filters to prevent high inrush current when the contacts close thus extending their life. |
