Is this just adding the switch cam to my F&R or do you mean to upgrade the F&R and add a switch cam?

Most F&R (Forward & Reverse switch) can be upgraded with the beefed up switch cam. Some F&Rs already have suffered heat damage and should be replaced with a new switch and the HD switch cam installed. IF the switch lugs show any color change, these are signs of heat damage and the switch should be swapped out. The plastic housing is usually compromised and the effected lug has sunk or shifted from it's original position compromising the contact.

So the best advice is to replace the F&R switch first, then replace the others. But buying a upgrade package would be cheaper in the long run.

YEah, that's it. You get the system ready to handle the increased voltage & amperage and THEN you increase the voltage and amperage. It sounds simple but I have seen people get the controller first and wind up burning up a F&R switch and wind up wasting money trying to save it.

My local shop recomended that I just upgrade the controller to an Alltrax 400amp. Said he has one in the shop. everything is stock, except he just put the 400amp controller. increase speed 2-3 mph and can smoke the tires with the increase in tourgue.
This is why I am on here asking questions.

lol he is just making a sale because there is no way he is smoking the tires

I just re-read my post. I left out a piece. He said if he put it up against the wall it would smoke the tires. sorry on pain meds, lucky I can type

A higher amp controller WILL NOT increase speed on a series cart, only increase the torque. Speed on a series cart is determined by voltage (assuming all other parts of the equation are nominal).

Thanks Gornoman.
That is what I thought. So will a 400amp controller be enough, or should I stick with the 500amp in my quest for 48volts

You been talking to my wife

I am ok with the speed of my buggy(20mph), but I would like a bit more torgue. I'm in charleston SC, so big hills are not an issue, but right now with my family of 4, she struggles on small hills.
