Star cart goes 4mph why?!

[Zachary25]

okay Im in the process of fixing my 48 volt Star cart got it "running" kinda it goes 4mph.. same speed forward & reverse solenoid clicks checked magnet not cracked I checked the wires going from motor to controller and are in the correct spots, I do how ever has 2 gauge cables on the F1 and F2 the stock ones were small I'd say like 8 gauge

Is this the same Star cart you purchased for $500 and upgraded it with a 600 amp controller?

[Zachary25]

Nope this one i got for free had a fried contoller and no batteries, picked up some batteries and took out the curtis 1268 controller out of the cart i paided $500 for wired up everything when to drive it and it goes 4mph checked the wires BUT i did put 2 gauge wires on the f1 and f2 for forward and reverse my $500 star cart is using very small f1 and f2 wires like 8 gauge or smaller

[Zachary25]

Does anyone know how to get the star cart into diagnostics mode?

[Zachary25]

okay so my guess is a bad speed magnet? any other thoughts?

would also like to know what it takes to fix it! I have a 2008 48v runs good up to 5mph , but no faster , but it will drag a locked up golf cart without any problem, it has power but no speed! please let me know if you solve the problem, THANKS LL Pippin

Check magnet and speed sensor. Solenoid can also cause the cart to run at 4MPH.

If you still have the Curtis controller in it, it will flash the amber light on the front of it and give out a code. If someone has a scan tool, that will tell you also.

thanks I will try the solenoid now , I put a new speed sensor, magnet, cables, so solenoid sounds good to me .

Did you get this problem fixed? I have the same issue going on

I also have the same problem, 4mph, tons of power, will tow a cart up a hill at 4mph, but mine also goes 8mph in reverse, does this make sense? I will check solenoid and speed sensor and get back to anyone with the news. All wires are cleaned and tightened. Problem is, I can't find my cart on this site, it a 2009 72v Miles Truck 25mph max speed(when running properly) I drove it just fine at 25mph for 2 days until all the sudden the power just felt like it dropped and then 4mph I go.
