Do I need an HD F&R Switch?

xstarpro · 02-08-2010, 04:40 PM

When I completed the 48 volt conversion last year I upgraded/replaced the F&R buss bars and studs. All worked fine for quite some time....Until...recently the infamous smell of an electric burn became more and more obvious....Ultimately I lost reverse and decided to breakdown the switch again....buss bars looked great but 2 of the springs had collapsed from (I assume heat).....I replaced all four springs (from Ace Hardware), cleaned up the connections, realigned and reinstalled...Cart goesm fine in F&R but seeing smoke coming from the switch after a good load (i.e. short stomp thru the woods).....The bottom wire is getting super hot...checked and all connections are tight....Starting to think I cheaped out and should have just replaced with an HD switch with the conversion....

Looking for your expert opinion

Questions:

***Why would the springs collapse to begin with?
***Doe's it matter which spring I used to replace--I.e. used some from ACE--same diameter etc...
***Should I just completely replace with an HD Switch? If so...Which (sponsor on this site) vendor carries the best one? I realize it a unique part--89 Marathon

THANK YOU IN ADVANCE FOR ANY HELP YOU CAN BE!

Any resistance will cause heat. I assume you put new bigger cables throughout? You do need a HD F&R when you go to those big batteries and 700 amp controller. Beefed up F&R switch assemblies are available at about twice the cost of stock unit. The unit you are looking for fits an 89 - 93 Ezgo....pm me if you want me to price it for you or check with any of the BGW sponsors

Sometimes the only gain you get is eliminating the minuses

He can expect this to be the last F&R he buys for quite some time to come

Is the wiring also a factor to the f&r when heat play's a part ?
