another fast in reverse thing

Gallachera89

So as yall know ive been chasing little issues around my 89 DS ..

Little history .. New 6 new 6v batteries, new 0gauge wires between them, still waiting to make the rest of the cables from the switch to controller to motor to solenoid, new fr switch and i have load tested the batteries from the last issue with the low end shudder under power(which i may have figured out), Has the D&D +40 torque motor and from what i gathered like a 700amp controller unless i looked up the model incorrectly

My question is though as many others have posted, in reverse this thing will literally do a burn out down the road .. can i just unmount the rearend and do a 180 with it so that my reverse is now forward and visa versa? or will the motor burn up faster because it now has a load on it the wrong way?

im open to any ideas

Simpler than you think. It must be wired backwards (either at the F/R lever or on the motor). The carts are designed to go real slow backwards. Simplest fix is to swap the S1 & S2 (OR A1 & A2) motor cables. Be careful to use two wrenches on each motor post when undoing them and tightening - to avoid spinning or twisting any wires from the stud inside the motor.

See now i have read this multiple times, but i dont see how changing the polarity of the motor would make it any faster?

and if i switch the s1 and s2 or the a1 and a2 its not goin to burn anything up is it?

You said it "burns rubber" in reverse...right? And you want it to "burn rubber" going forward...yes? Changing the motor polarity reverses that - so...fast in forward and slow in reverse.

No, you won't burn anything - that's how reverse is accomplished by the F/R lever - it physically reverses polarity on the motor. Make sure you detach your battery pack negative cable and wrap it in a cloth or something so there is no power or arcing possible when you swap them.

well i understand how the switch works but i didn't think switching the cables would make a difference .. if the motor only spun so much going one way how would it make a difference with the wires swapped.. guess im thinking to much into it .. ill give it a whirl.. now if i swap s1 and 2 and it doesn't change.. i presume i put them back and then swap a1 and a2 correct ?

No - if S1 and S2 doesn't get you what you want - then A1 & A2 won't help because it is essentially the same thing. One reverses the field coil (which reverses polarity) and the other reverses the armature (which reverses polarity). Just pick one - and go with it.

roger that sir i do appreciate it .. ill let yo know if anything happens

Don't forget to disconnect the pack before starting - that is the biggest cart killer around if you leave the pack connected while doing wiring changes.

Also, that is only a solution if your cart is currently going in the opposite direction the FNR lever is pointing to, meaning it goes Forward when the lever in on Reverse.

Come to think of it, he didn't say that - he just said his cart goes-like-the-wind backwards and is a slug going forward. What would he do to solve that Sergio - the cart appears to have aftermarket controller and motor.
