ef1 engine electrical problems

ive got a 2021 ezgo valor with that ef1 fuel injected engine. I have no power at switch

If the ignition switch in your EZGO Valor follows the wiring pattern of earlier models you might encounter limitations. In such cases, power typically flows through the gas pedal switch before reaching the ignition switch. When the pedal is pressed down, it completes the circuit within the pedal switch, allowing power to flow from the battery to the ignition switch. This setup is designed to prevent accidental or unauthorized activation of the ignition system, enhancing safety and security by integrating the pedal switch into the power supply circuit. While this configuration may present limitations for certain accessory installations, it serves to enhance the overall safety and reliability of the carts electrical system.

If you happen to have a 3 position key switch fitted, like those often found in Workhorse models, there's a workaround. By using position 3 exclusively for accessories, you can effectively bypass this limitation. Just remember to turn off the key when parking to avoid draining the battery. This setup prevents your accessories, such as a radio, from cutting out whenever you release the gas pedal. Let me know if this answers your question or if you need further assistance feel free to ask!

all wires at ignition are dead

So in this situation we're dealing with a pretty common headache in these carts. The ECU and ISG act as the brain of the engine management system, receiving input from various sensors and controls to regulate fuel injection, ignition, and other critical engine functions. However, when one malfunctions, as indicated by the lack of power or failure of the cart to wake up, it can lead to significant operational issues like you're currently experiencing. Now here's the kicker, its common for any of these to decide to call it quits, and when they do, it's trouble.

One big issue were seeing is the placements of the computers themself. Ones tucked away in a spot where it can get real hot, and the other right above the motor (heat rises). When that happens, they can overheat and, well, kick the bucket. So even though it's doing its job fine and dandy, that extra heat and vibration can cause it to go. And when one decides to quit, it's like the whole cart just shuts down. No power to the starting relay, fuel pump, nada. To make matters worse, getting your hands on replacements ain't no walk in the park, they're in high demand and short supply, leaving folks waiting in line just to get their carts back up and running. Perhaps with you providing a bit of backstory we can piece together the puzzle.

sounds like i got a lemon, i bought this thing new so i wouldnt have problems, i bet this car dont have 50 hrs on it. but waranty is up

That's frustrating especially since you bought this brand new to avoid exactly these kinds of issues. Skip the dealership hassle and go straight to the source by reaching out to EZGO directly. Head to www.ezgo.com and scroll down to the bottom of the page where you'll find contact options via email and phone. You can also reach out to them on their social media platforms like Facebook or Twitter, which are also listed on their website. Filing a claim and getting in touch with a representative can help expedite the process and potentially lead to a faster resolution.

Given the nature of the issue, it's possible that this could be recalled and covered at some point, so it's important to keep the lines of communication open with EZGO. Remember to keep us in the loop. Sharing your experience can provide valuable insight for people searching the web facing similar challenges, so please keep us updated on your progress.

In the meantime, since replacements are scarce and if you can't afford to wait for a solution or need your rig up and running ASAP, consider reaching out to a computer rebuilder. Heat related issues with computers are common in cars and automobiles, and there are plenty of rebuilders on platforms like eBay that deal with fixing all sorts of computers daily. Sort search results by distance and check for local rebuilders who you could maybe drive to and have them take a look at your computer and see if it's rebuildable. Here is an example for that type of search

well started messin with this thing today, turn the ignition on pulled 10 amp fuse out then plug it back in, the one by the batterie, now all is good again
ill see how long it last but so far so good, maybe this little info could help someone else, thanks for the input.

Thank you for the update. Also thanks to golfcartg for sharing your wisdom.

Pulling out the 10 amp fuse is akin to hitting the electrical reset button. By doing so, you're cutting off power to components like the ignition and fuel injection system. It's like giving the carts electrical system a breather, clearing out any glitches or snags that may have cropped up. This quick fix can often resolve issues like electrical quirks or engine performance hiccups when in a pinch. Besides pulling the fuse, another way to achieve the same result is by disconnecting the battery. By disconnecting the battery terminals (starting with the negative terminal to avoid electrical mishaps), you effectively cut off power to the carts electrical system. Just remember, it might only be a temporary solution, and deeper troubleshooting may be necessary.

To troubleshoot whether the issue lies specifically within the ISG or ECU, instead of immediately resorting to pulling the fuse, consider a more targeted approach. If the problem occurs again, begin by disconnecting the plug(s) on the ISG or ECU and wait for 15 seconds before reconnecting it. If the issue persists, repeat the same procedure with the other. If the problem resolves after disconnecting and reconnecting either the ISG or ECU, it indicates that particular item may be faulty and in need of replacement.
