overheating
I just recently purchased and installed a 36v 8.6 hp high speed d&d motor. I have 4 gauge wire and installed a 375 amp controller. It's a 2006-08 36v ezgo series model golf cart lifted, 14" wheels. I've also upgraded to a heavy duty f&r switch, and solenoid (solenoid maybe cheap ? Bought off ebay). Since I've installed everything I've had no problems (maybe a week, 2+ miles a day), except yesterday. I was riding around (maybe 1 mile) and it slowed way down. I pulled over and started checking everything out and everything was VERY hot. What could possibly be the problem? *thank you

Re: overheating
Please be more specific on "everything's hot". Also, tell us the size tire, as that's where the rubber meets the road.

Re: overheating
Something is wrong if your 4 gauge cables are getting "hot" with only 375 amps. Solenoid gets hot under normal use, but we can't rule that out. The motor can safely get too hot to touch, but if you lick your finger and touch it, it shouldn't sizzle - kinda like our Moms did to see if the iron was hot enough.
What controller do you have? It may have gone into limp mode if it was overheating. Does it run normal after it's cooled down? |

Re: overheating
it's a ezgo controller. Yes after it cools down it runs fine, but after a mile or so it overheats again and slows down

Re: overheating
Ok, that is most likely the cause of your problem. Now, allow scottyb or others on here to tell you what you are going to need to buy and install to allow you to operate that cart with 23 inch tires, in the manner that you intend to use it. You might as well let them know how you intend to use the cart, the sort of terrain you intend to operate on, the pressure rating of the tires (determines tire drag), and any other load factors such as rear seats, cargo bed, ect. They can take these factors into account when calculating what upgrade equipment will be required. Welcome to BGW and good luck with your project.
