DCS troubleshooting
There is a closed thread for DCS troubleshooting and it has a couple of PDF files in them. However, when I try to download them, I get a message they are invalid. Does someone have them and can email them to me?

Re: DCS troubleshooting
Please disregard my last message, I logged in on my laptop and was able to download them.
Tomorrow night I'm digging into a buddies DCS that keeps blowing controllers. They work for a while, but then typically they'll only go forward or reverse for a while, not both, and then they'll quit. Any advice is much appreciated. Sent from my SM-G950U1 using Tapatalk |

The DCS was EZGO's first attempt with a sepex drive and the controller has a fatal flaw, no under-voltage protection. If the cart has taller than stock (18") tires or a rear seat, a stock DCS controller won't last very long. |

Stock cables were 6Ga, so the voltage drop of the stock cables is higher. The contacts of the stock solenoid are only rated for 85A and are most likely pitted and burnt, adding more voltage drop. It takes more amps to turn taller than stock tires, so the more amps drawn, the more the battery pack voltage drops. The battery pack voltage decreases as the SoC (State of Charge) decreases and the lower the SoC, the greater the voltage drop per 100A of draw, so the voltage drop at the end of a trip when the battery is partially discharged is greater than it is at the beginning of the trip when batteries are fully charged. The above issue are what a well designed, output protected controller has to contend with. A poorly designed controller without output protection, such as the Curtis 1206SX, doesn't stand a chance of surviving. |
