Default Fwd rev switch burnt?

Hello everyone first post here. Just picked up a 2004 ez go txt 36v does have 2Ē lift on it as well as bigger tires (forgot the exact size) it has been riding fine for the month then two days ago it got a little funny jumping into gear once I pressed the throttle down. Then yesterday I was pulling a tree branch to my backyard in reverse And of all the sudden stopped and I smelt burning which seemed from the fwd rev switch. I tried putting it into forward and reverse and nothing but clicking on both and I donít even get a buzz sound in reverse. I searched a few forum and someone may have had problem similar but someone said to jack up the rear and test something that way. Iím no mechanic so if I donít speak your language Iím sorry. Also the guy before me replaced same switch a few months ago he said and it is heavy duty one. Batteries are within 4 months old. Also now when I try to go into forward it is a real struggle like I almost have to rip the handle into forward but reverse seems easier. Cable connections all seem tight I will say the gauges only seem like about a 6. Any help would be appreciated to try before I buy. Thank you!

There's no fixing that one, the damage is already done. New F&R time for you. There are some other options, check out ScottyB's store at www.cartsunlimited.net for HD f&r, or switching relay HD f&r.

You are asking your cart to do too much with oversized tires and pulling a branch. Don't worry, a series cart can be upgraded to become a real work horse. You'll want a HD FNR or reversing contactor as mentioned above, but you also want to upgrade your controller, solenoid, and cables. Motor will serve you fine. When it's time to replace the batteries, you will be able to buy six 8 volt batteries and be at 48, which you'll love.

Go here and read up:

https://www.cartsunlimited.net/upgrade-suggestions.html

You should read up here for new batteries. Also, find your manufacturer's website and get the recommended torque for your terminals. They are stainless steel studs encased in lead, which is very soft. Since you say you aren't mechanically inclined, it would be very easy to under or over tighten them. The torque rating is in inch-pounds, not foot-pounds, so if you ask a friend to help you and he brings over a BIG torque wrench, remember to divide by 12 to get inch pounds, or 110 in-llbs = 9ish ft-lbs.

It is tempting to view the golf cart as a new lawn tractor or workhorse around the property. Electric carts are limited in that the motor will draw additional amperage when operation includes added loads. Dragging a load especially at slow speed or even extended slow operation has proved to created excessive heat in the motor and other components like the F&R switch in the series drive carts.
We have to keep the original engineered design in mind which is a transporter for 2 people 300 yards and rest... aka golf. Today's trend for bigger tires exasperates the load issues.

Can I wait on the controller and just do solenoid 2 gauge cables and the switch? I was looking on amazon and I did see the heavy duty 300amp 36v solenoid would that be fine with heavy duty f&r switch? Also should the cables be a lot smaller running to the front of the f&r switch?
Thank y’all for the help I appreciate it.

You get what you pay for. I bought all of my upgrades from site sponsors. They keep the lights on here, so we can get free advise, and share it.

You need a HD FNR, and you won't find a better one than here:

https://www.cartsunlimited.net/

Yes you can just upgrade the FNR now. The cables will survive, as long as you take care of them. Your solenoid will not. I killed two before upgrading. Attached solenoid was killed at 36 volts with stock tires, stock everything. You have oversized tires. Worst thing that will happen when you kill your controller is a fireworks show, which we all read about mere hours ago from another member. That's rare. It's more likely you'll have to tow it home.

I'd buy a solenoid that will allow me to use it when I upgrade to 48 volts at battery change time. Anything else is throw away, which might make ecnomic sense, not knowing what you are looking at.

Sound advise yurtle. You want to buy quality replacement parts once. Some of the cheap parts you see online tend to have limited lifetimes.

Site sponsors here tend to have good prices and quality parts ... which are cheaper for you in the long run.

Honestly I got on the forum so quick and don’t realize they had a store I’m always for supporting them because y’all are helping me. I will try to figure out what solenoid I need. Do I just take cables off the battery to disconnect the power and then use same wires for the f&r and the solenoid. How do I know how many volts I need on the solenoid? I see a few different options. Yurtle if I could hug you I would lol

Drugs, not hugs. Or do I have that backwards. I've been playing with electrical things and internal combustion things since I was a wee little pup, but I still had a lot to learn about electric golf carts so you aren't alone. You're in good hands - careful. Here is one of the best places to read about how they work and options. There isn't a "store" but up top you'll see a link for "site sponsors".

Fast forward past drive type, as we know you have a series.

This place doesn't have a "store", but some good folks around here do operate business. (See site sponsors). They advertise here, and play by the rules. There was once a huge forum that was totally centered around it's own store, but their forum has collapsed due to BS like deleting posts that weren't favorable to "the store".. around here, if you get a bad reputation as a retailer, you have to own it. (Or get the boot). I was once a part of that other forum, but haven't signed in there for many years. Not even sure if BuggiesUnlimited forum even still exists in the form of a place to ask random stuff, without that being the last ditch version of "tech support" for the lousy service they provide.

Does BU forum still exist? I won't waste my time to go see ...
