I'm Stumped (loss of power)

Cuz

My 1983 Club Car has been a dog ever since I bought it.. I installed a 7" lift and 34" tires and then purchased a rebuilt motor from EMP based off my tire size.. They said speed would be about 16mph.. After geting the new motor installed, it is exactly the same as it was so I figured it had to be the batteries. So I went out and bought 6 new batteries, installed them and even upgraded all my battery wires to 4awg and still have the exact same problem.. I have an older 5 solenoid cart and all 5 solenoids are firing.. In reverse it barely has enough power to push the cart and in forward it slooooowly works its way up to speed (same as it did before my motor and battery upgrade)... My stock 92 Ezgo can run 3 laps before this one even completes one lap, WTH?

Any ideas?

Thanks
Cuz

Cuz? What were you thinking? 34 inch tires and 2 or 3 hp electric cart!? I don't run that much tire on a 25hp gas engine.... You must convert from solenoids to solid state and up your voltage to 48 ..... are you sure you want to keep the truck tires

Cuz

Sorry, I had a brain fart, they are 24" tires

Good Grief Man! Bet you thought you could slide that one on by me

Hey I still think you can go to 48v and be happy

Cuz

This thing has to have more power than its putting out right now, especially with the motor upgrade.. If I stomp on it and all 5 solenoids fire, it slowly takes off and takes time to build speed.. My 92 Ezgo is all stock and also a 36v cart and I put 22"s on it but it has way more power and tons of torque in comparison (actually there is no comparison)..

Here's the way I look at it, but correct me if I'm wrong, if all 5 solenoids fire, doesnt it apply full voltage to the motor? And if so, why does it act like I'm slowly giving it gas (very slowly)? Its so bad in reverse that I can stop the cart from moving by just putting my foot on the tire while flooring it, does that make sense?

Eidt: In reverse there isnt even enough power to climb over a hammer handle that I left laying on the floor..

I think I found it, if anyone really cares to know

My first solenoid was firing but must have a bad contact in it because no voltage was passing through it.. Instead, the power then went through the coils on that resistor to feed the other contactors and I was only getting 12v to my motor.. Cant wait to see what happens when all 40+ volts are applied now

Ok, off to get a new solenoid
